Seed plants do not have swimming sperm Gymnosperms reproduce with pollen and seeds |
Angiosperms have flowers and fruit.
Angiosperms have flowers and fruits. Peanuts, grapes, strawberries and squash are all plants. They are angiosperms, or flowering plants. An angiosperm is a seed plant that produces flowers and fruit. Most species of plants living now are angiosperms. |
Reproduction Cycles of Angiosperms
The reproductive cycles of angiosperms and gymnosperms are alike in many ways. Both angiosperms and gymnosperms have separate male and female reproductive structures. In some species, male and female parts grow on the same plant, but in others there are separate male and female parts.
In angiosperms the sperm and egg cells are contained in a flower. The flower is the reproductive structure of an angiosperm. Egg cells develop in a part of the flower called the ovary. Once the eggs are fertilized and the seed or seeds form, the ovary wall thickens and the ovary becomes a fruit.
