Petal - Petals are used to attract insects into the flower, they may have guidelines on them and be scented.
Stigma- Is covered in a sticky substance that the pollen grains will adhere to.
Style- The style raises the stigma away from the Ovary to decrease the likelihood of pollen contamination. It varies in length.
Ovary This protects the ovule and once fertilisation has taken place it will become the fruit.
Ovule- The Ovule is like the egg in animals and once fertilisation has taken place will become the seed.
Receptacle- This is the flower's attachment to the stalk and in some cases becomes part of the fruit after fertilisation e.g. strawberry.
Flower stalk- Gives support to the flower and elevates the flower for the insects.
Nectary- This is where a sugary solution called nectar is held to attract insects.
Sepal Sepals protect the flower whilst the flower is developing from a bud.
Filament- This is the stalk of the Anther.
Anther- The Anthers contain pollen sacs. The sacs release pollen on to the outside of the anthers that brush against insects on entering the flowers. The pollen once deposited on the insect is transferred to the stigma of another flower or the same flower. The ovule is then able to be fertilised.
GUIDE QUESTIONS:
a. The transfer of pollen from the anthers of a flower to the stigma of the same flower or of another flower. Pollination is a prerequisite for fertilization: the fusion of nuclei from the pollen grain with nuclei in the ovule. Fertilization allows the flower to develop seeds.
Some flowers will develop seeds as a result of self-pollination, when pollen and pistil are from the same plant, often (but not always) from the same flower. Other plants require cross-pollination: pollen and pistil must be from different plants.
b. An animal that moves pollen from the anthers to the stigmas of flowers, thus effecting pollination. Animals that are known to be good pollinators of flowers include bees, butterflies, hummingbirds, moths, some flies, some wasps, and nectar feeding bats. Most plants need help moving pollen from one flower to the pistil of another. Wind moves the pollen for some plants such as grasses like corn. Animal pollinators move pollen for many other flowering plants.
c. Pollination is a keystone process in both human managed and natural terrestrial ecosystems. It is critical for food production and human livelihoods, and directly links wild ecosystems with agricultural production systems. The vast majority of flowering plant species only produce seeds if animal pollinators move pollen from the anthers to the stigmas of their flowers. Without this service, many interconnected species and processes functioning within an ecosystem would collapse.

* Stamen
This is the male part of the flower. It is made up of the filament and anther, it is the pollen producing part of the plant. The number of stamen is usually the same as the number of petals.
* Anther
This is the part of the stamen that produces and contains pollen. It is usually on top of a long stalk that looks like a fine hair.
* Filament
This is the fine hair-like stalk that the anther sits on top of.
*
Pistil
This is the female part of the flower. It is made up of the stigma, style, and ovary. Each pistil is constructed of one to many rolled leaflike structures.
* Stigma
One of the female parts of the flower. It is the sticky bulb that you see in the center of the flowers, it is the part of the pistil of a flower which receives the pollen grains and on which they germinate.
* Style
Another female part of the flower. This is the long stalk that the stigma sits on top of.
* Ovary
The part of the plant, usually at the bottom of the flower, that has the seeds inside and turns into the fruit that we eat. The ovary contains ovules.
* Ovule
The part of the ovary that becomes the seeds.
* Petal
The colorful, often bright part of the flower. They attract pollinators and are usually the reason why we buy and enjoy flowers.
* Sepal
The parts that look like little green leaves that cover the outside of a flower bud to protect the flower before it opens.
a. Pollination is the process by which pollen is transferred in plants, thereby enabling fertilization and sexual reproduction.
Abiotic pollination refers to situations where pollination is mediated without the involvement of other organisms. Only 10% of flowering plants are pollinated without animal assistance.
biotic pollination is the various flower traits (and combinations thereof) that differentially attract one type of pollinator or another are known as pollination syndromes.
b. Insect pollinators such as honeybees (Apis mellifera),bumblebees (Bombus terrestris), and butterflies (Thymelicus flavus)have been observed to engage in flower constancy, which means they are more likely to transfer pollen to other conspecific plants.This can be beneficial for the pollenisers, as flower constancy prevents the loss of pollen during interspecific flights and pollinators from clogging stigmas with pollen of other flower species.
c.Pollination is a keystone process in both human managed and natural terrestrial ecosystems. It is critical for food production and human livelihoods, and directly links wild ecosystems with agricultural production systems. The vast majority of flowering plant species only produce seeds if animal pollinators move pollen from the anthers to the stigmas of their flowers. Without this service, many interconnected species and processes functioning within an ecosystem would collapse.

What are the benefits? Plants benefit from pollinators because the movement of pollen allows them to reproduce by setting seeds. However, pollinators don't know or care that the plant benefits. They pollinate to get nectar and/or pollen from flowers to meet their energy requirements and to produce offspring. In the economy of nature, the pollinators provide an important service to flowering plants, while the plants pay with food for the pollinators and their offspring

flowers parts and function
Calyx
The calyx, or the sepals, are the first part of a flower to develop. They anchor the flower to the stem, hold the petals in place and protect the flower as it matures.
Corolla
The scientific term for the petals of a flower is corolla. They are the showy part of a flower and come in all kinds of colors. If the flower is scented, the corolla is the fragrant part which serves to attract insects and birds. The animals help the flower pollinate.
Stamen
The male reproductive organs of a flower are the stamen. They produce the pollen and have two parts. The filament is like a small stem that ends in a swelling called the anther. The pollen forms inside the anther in four pockets. When the pollen is ripe, these pockets rupture to release the pollen.
Pistil
The female reproductive organs of the flower, pistils, are where the seeds form after they have been pollinated. If the flower has a compound pistil, the segments are called carpels. The stigma at top of the pistil is sticky enough to capture particles of pollen. This area leads to a tube, the style. The pollen moves through the tube to the plant's ovary. Inside the ovary, ovules, form into seeds which will produce new plants if they first have been pollinated and second, fertilized.

Anther The Anthers contain pollen sacs. The sacs release pollen on to the outside of the anthers that brush against insects on entering the flowers. The pollen once deposited on the insect is transferred to the stigma of another flower or the same flower. The ovule is then able to be fertilised.
Pollination: The transfer of pollen from the anthers of a flower to the stigma of the same flower or of another flower. Pollination is a prerequisite for fertilization: the fusion of nuclei from the pollen grain with nuclei in the ovule. Fertilization allows the flower to develop seeds.
Some flowers will develop seeds as a result of self-pollination, when pollen and pistil are from the same plant, often (but not always) from the same
flower. Other plants require cross-pollination: pollen and pistil must be from different plants.
Most plants need help moving pollen from one flower to the pistil of another. Wind moves the pollen for some plants such as grasses like corn. Animal pollinators move pollen for many other flowering plants.
An animal that moves pollen from the anthers to the stigmas of flowers, thus effecting pollination. Animals that are known to be good pollinators of flowers include bees, butterflies, hummingbirds, moths, some flies, some wasps, and nectar feeding bats.
Plants benefit from pollinators because the movement of pollen allows them to reproduce by setting seeds. However, pollinators don't know or care that the plant benefits. They pollinate to get nectar and/or pollen from flowers to meet their energy requirements and to produce offspring.

flowers parts and function
Calyx
The calyx, or the sepals, are the first part of a flower to develop. They anchor the flower to the stem, hold the petals in place and protect the flower as it matures.
Corolla
The scientific term for the petals of a flower is corolla. They are the showy part of a flower and come in all kinds of colors. If the flower is scented, the corolla is the fragrant part which serves to attract insects and birds. The animals help the flower pollinate.
Stamen
The male reproductive organs of a flower are the stamen. They produce the pollen and have two parts. The filament is like a small stem that ends in a swelling called the anther. The pollen forms inside the anther in four pockets. When the pollen is ripe, these pockets rupture to release the pollen.
Pistil
The female reproductive organs of the flower, pistils, are where the seeds form after they have been pollinated. If the flower has a compound pistil, the segments are called carpels. The stigma at top of the pistil is sticky enough to capture particles of pollen. This area leads to a tube, the style. The pollen moves through the tube to the plant's ovary. Inside the ovary, ovules, form into seeds which will produce new plants if they first have been pollinated and second, fertilized.

* Stamen
This is the male part of the flower. It is made up of the filament and anther, it is the pollen producing part of the plant. The number of stamen is usually the same as the number of petals.
* Anther
This is the part of the stamen that produces and contains pollen. It is usually on top of a long stalk that looks like a fine hair.
* Filament
This is the fine hair-like stalk that the anther sits on top of.
*
Pistil
This is the female part of the flower. It is made up of the stigma, style, and ovary. Each pistil is constructed of one to many rolled leaflike structures.
* Stigma
One of the female parts of the flower. It is the sticky bulb that you see in the center of the flowers, it is the part of the pistil of a flower which receives the pollen grains and on which they germinate.
* Style
Another female part of the flower. This is the long stalk that the stigma sits on top of.
* Ovary
The part of the plant, usually at the bottom of the flower, that has the seeds inside and turns into the fruit that we eat. The ovary contains ovules.
* Ovule
The part of the ovary that becomes the seeds.
* Petal
The colorful, often bright part of the flower. They attract pollinators and are usually the reason why we buy and enjoy flowers.
* Sepal
The parts that look like little green leaves that cover the outside of a flower bud to protect the flower before it opens.
a. Pollination is the process by which pollen is transferred in plants, thereby enabling fertilization and sexual reproduction.
Abiotic pollination refers to situations where pollination is mediated without the involvement of other organisms. Only 10% of flowering plants are pollinated without animal assistance.
biotic pollination is the various flower traits (and combinations thereof) that differentially attract one type of pollinator or another are known as pollination syndromes.
b. Insect pollinators such as honeybees (Apis mellifera),bumblebees (Bombus terrestris), and butterflies (Thymelicus flavus)have been observed to engage in flower constancy, which means they are more likely to transfer pollen to other conspecific plants.This can be beneficial for the pollenisers, as flower constancy prevents the loss of pollen during interspecific flights and pollinators from clogging stigmas with pollen of other flower species.
c.Pollination is a keystone process in both human managed and natural terrestrial ecosystems. It is critical for food production and human livelihoods, and directly links wild ecosystems with agricultural production systems. The vast majority of flowering plant species only produce seeds if animal pollinators move pollen from the anthers to the stigmas of their flowers. Without this service, many interconnected species and processes functioning within an ecosystem would collapse.

C. In agro-ecosystems, pollinators are essential for orchard, horticultural and forage production, as well as the production of seed for many root and fibre crops. Pollinators such as bees, birds and bats affect 35 percent of the world's crop production, increasing outputs of 87 of the leading food crops worldwide, plus many plant-derived medicines. It has been estimated that at least 20 genera of animals other than honeybees provide pollination services to the world's most important crops. For human nutrition the benefits of pollination include not just abundance of fruits, nuts and seeds, but also their variety and quality; the contribution of animal-pollinated foodstuffs to human nutritional diversity, vitamin sufficiency and food quality is substantial.

Parts/Function of the Flower
Stem - holds the flower away from the ground so insects can pollinate the
flower. It also carries water from the root to the flower.
Leaves - make food for the flower or plant by turning sunlight into sugar.
This is photosynthesis.
Stamen - there are usually a lot of stamens on the flower which help to make
the pollen.
Anther - is at the top of the stamen. It makes the pollen. In the lily family,
these usually have brown pollen on them.
Petals - are bright in color to attract insects or birds.
Stigma - female part of the plant. It is usually in the middle of the flower.
It has a slit at the top where pollen carried by insects or birds enters.
Sepal - “leaves” that protect the flower while it is developing inside the bud.
If these turn into petals themselves they are called PETALS.
Pollination: The transfer of pollen from the anthers of a flower to the stigma of the same flower or of another flower. Pollination is a prerequisite for fertilization: the fusion of nuclei from the pollen grain with nuclei in the ovule. Fertilization allows the flower to develop seeds.

Pollination: The transfer of pollen from the anthers of a flower to the stigma of the same flower or of another flower. Pollination is a prerequisite for fertilization: the fusion of nuclei from the pollen grain with nuclei in the ovule. Fertilization allows the flower to develop seeds.
Most plants need help moving pollen from one flower to the pistil of another. Wind moves the pollen for some plants such as grasses like corn. Animal pollinators move pollen for many other flowering plants.
Plants benefit from pollinators because the movement of pollen allows them to reproduce by setting seeds. However, pollinators don't know or care that the plant benefits. They pollinate to get nectar and/or pollen from flowers to meet their energy requirements and to produce offspring. In the economy of nature, the pollinators provide an important service to flowering plants, while the plants pay with food for the pollinators and their offspring.
An animal that moves pollen from the anthers to the stigmas of flowers, thus effecting pollination. Animals that are known to be good pollinators of flowers include bees, butterflies, hummingbirds, moths, some flies, some wasps, and nectar feeding bats.

Pollination is a necessary step in the reproduction of flowering plants, resulting in the production of offspring that are genetically diverse.
The study of pollination brings together many disciplines, such as botany, horticulture, entomology, and ecology. The pollination process as an interaction between flower and vector was first addressed in the 18th century by Christian Konrad Sprengel. It is important in horticulture and agriculture, because fruiting is dependent on fertilization, which is the end result of pollination.

* Style
Another female part of the flower. This is the long stalk that the stigma sits on top of.
* Ovary
The part of the plant, usually at the bottom of the flower, that has the seeds inside and turns into the fruit that we eat. The ovary contains ovules.
* Ovule
The part of the ovary that becomes the seeds.
* Petal
The colorful, often bright part of the flower. They attract pollinators and are usually the reason why we buy and enjoy flowers.
* Sepal
The parts that look like little green leaves that cover the outside of a flower bud to protect the flower before it opens.

Self-pollination occurs when pollen from one flower pollinates the same flower or other flowers of the same individual.
B.When animals such as bees, butterflies, moths, flies, and hummingbirds pollinate plants, it's accidental. They are not trying to pollinate the plant. Usually they are at the plant to get food, the sticky pollen or a sweet nectar made at the base of the petals. When feeding, the animals accidentally rub against the stamens and get pollen stuck all over themselves. When they move to another flower to feed, some of the pollen can rub off onto this new plant's stigma.
C.Pollinators such as bees, birds and bats affect 35 percent of the world's crop production, increasing outputs of 87 of the leading food crops worldwide, plus many plant-derived medicines. It has been estimated that at least 20 genera of animals other than honeybees provide pollination services to the world's most important crops. For human nutrition the benefits of pollination include not just abundance of fruits, nuts and seeds, but also their variety and quality; the contribution of animal-pollinated foodstuffs to human nutritional diversity, vitamin sufficiency and food quality is substantial.

Flower stalk-Gives support to the flower and elevates the flower for the insects.
Nectary-This is where a sugary solution called nectar is held to attract insects.
Sepal-Sepals protect the flower whilst the flower is developing from a bud.
Filament-This is the stalk of the Anther.
Anther -The Anthers contain pollen sacs. The sacs release pollen on to the outside of the anthers that brush against insects on entering the flowers. The pollen once deposited on the insect is transferred to the stigma of another flower or the same flower. The ovule is then able to be fertilised.

GUIDE QUESTIONS:
A. Pollination is the process by which pollen is transferred in plants, thereby enabling fertilization and sexual reproduction.
http://en.wikipedia.org/wiki/Pollination
B. Wind moves pollen for some plants like grass and corn. Animal pollinators move pollen for many flowering plants.

C. In agro-ecosystems, pollinators are essential for orchard, horticultural and forage production, as well as the production of seed for many root and fibre crops. Pollinators such as bees, birds and bats affect 35 percent of the world's crop production, increasing outputs of 87 of the leading food crops worldwide, plus many plant-derived medicines. It has been estimated that at least 20 genera of animals other than honeybees provide pollination services to the world's most important crops. For human nutrition the benefits of pollination include not just abundance of fruits, nuts and seeds, but also their variety and quality; the contribution of animal-pollinated foodstuffs to human nutritional diversity, vitamin sufficiency and food quality is substantial.

PETAL- are used to attract insects into the flower, they may have guidelines on them and be scented.
STIGMA-Is covered in a sticky substance that the pollen grains will adhere to.
Style The style raises the stigma away from the Ovary to decrease the likelihood of pollen contamination. It varies in length.
OVARY-This protects the ovule and once fertilisation has taken place it will become the fruit.
OVULE-The Ovule is like the egg in animals and once fertilisation has taken place will become the seed.

Functions of the parts of a flower
Part Function
1. Pollen sperm of the plant
2. Anther contains the pollen
3. Filament stalk on which anther is attached, longer in wind pollinated plants
4. Stamen male part of plant, parts 1-3 combined
5. Stigma sticky part to which pollen attaches
6. Style simply, a tube through which sperm travel to seeds
7. Ovary contains the seeds, later to become the fruit of the plant
8. Pistil female part of the plant, parts 5-7 combined
9. Seeds future plants, contained in the ovary
10. Sepal tiny leaf-like structures that protect the flower as a bud
11. Petals brightly colored, used to attract pollinators
12. Stem supports the flower
A.
Transfer of pollen grains from the anther to the stigma of a flower by insects,water and wind is called pollination.pollination may be grouped as of 2 types-
1.self pollination
2.cross pollination
self pollination-if the pollen grains land on the stigma of the same flower then it is called self pollination.
cross pollination-if the pollen grains land on the stigma of the other flower or the flower of the same type is called cross pollination.
without pollination fertilization could not take place.now the question arises how the pollen grains land on the stigma.
so the answer is that stigma is sticky so that the pollen grains could land on them
B.Pollen is a fine to coarse powder containing the microgametophytes of seed plants, which produce the male gametes (sperm cells). Pollen grains have a hard coat that protects the sperm cells during the process of their movement between the stamens to the pistil of flowering plants or from the male cone to the female cone of coniferous plants. When pollen lands on a compatible pistil of flowering plants, it germinates and produces a pollen tube that transfers the sperm to the ovule of a receptive ovary. Individual pollen grains are small enough to require magnification to see detail.
c.Pollination is a keystone process in both human managed and natural terrestrial ecosystems. It is critical for food production and human livelihoods, and directly links wild ecosystems with agricultural production systems. The vast majority of flowering plant species only produce seeds if animal pollinators move pollen from the anthers to the stigmas of their flowers. Without this service, many interconnected species and processes functioning within an ecosystem would collapse.

Guide Question:
1.Pollination is the process by which pollen is transferred in plants, thereby enabling fertilization and sexual reproduction.
-Abiotic pollination refers to situations where pollination is mediated without the involvement of other organisms. Only 10% of flowering plants are pollinated without animal assistance while organisms that carry or move the pollen grains from the anther to the receptive part of the carpel or pistil.
2.Flowering plants have several different parts that are important in pollination. Flowers have male parts called stamens that produce a sticky powder called pollen. Flowers also have a female part called the pistil. The top of the pistil is called the stigma, and is often sticky. Seeds are made at the base of the pistil, in the ovule.
