What are the functions of the parts of a flower?

Angiosperms are flowering plants in which the seeds are enclosed in a fruit. Angiosperms are the
most common plants on Earth.
They are important to all life because they form the basis for the diets
of most animals.
Flowers are complex structures made up of many parts.
Some parts are involved in fertilization and
seed production; other parts are involved in pollination.
Flowers come in many different shapes,
sizes, colors, and configurations, but all share a simple, basic structure made up of four kinds of
organs: sepals, petals, stamens (male reproductive organs) and pistils (female reproductive organs).
Pollination is the process of transferring pollen grains from the stamen to the stigma.
Pollen can be
carried by wind or by animals such as beetles, butterflies, moths, bees, flies, hummingbirds, and bats
that feed on a flower’s nectar and transfer pollen grains from the stamen to the stigma.
have more than one ovule.
Pollination of these flowers requires that at least one pollen grain must
land on the stigma for each ovule contained in the ovary.
Fertilization follows pollination.
It results in an ovule forming an embryo and endosperm.
