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. Some flowers 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. The
