1. It has both sperm-producing anthers and egg-producing ovaries.
2. In a flower, the anther produces the pollen grains, each of which carries sperm.
3.
4. Once fertilization occurs, the ovary develops into fruit, and the ovule develops into the seed coat (protecting the embryo). Since the embryo is stuck inside a protective coating, it needs a packed lunch to keep it alive until the embryo grows into a photosynthesizing plant; this food source is the endosperm.
5. Imperfect flowers cannot self-fertilize because an imperfect flower has ONLY eggs or sperm.
6. Pollination is when a pollen grain lands on the stigma. Fertilization is when the egg in the ovary is fertilized by one of the two sperm that travels down the style through the tube created by the third cell in the pollen grain, called a tube nucleus. The second sperm will fertilize the polar nuclei, turning into food for the embryo, called endosperm.
7. [outermost] petals → ovary → ovule → egg [innermost]
8. The fruit itself does not help protect the embryo (that is the seed coat’s job). The fruit, however, may be eaten by an animal that passes the indigestible seeds through its poop, thus helping to spread the seeds (and embryos) throughout the ecosystem.
