The implications/importance of plant female gametophyte development in the biosphere are discussed.
- Strygamete formation: In this process the strygametophyte develops. The main function of the female gametophyte is to produce female gametes or ovules. An ovule is produced in each female gametophyte.
- Fertilization: The prerequisite for fertilization is the production of sperm and egg. The female gametophyte produces ovules which participate in fertilization.
- Origin of seeds: The main source of food in the living world is seeds. Spermatozoa fuse with secondary nucleus of female gametophyte to produce seed.
- Fertilization: In this process, the ovum unites with the sperm to form a zygote. After the zygote is formed, the ovum develops into a seed.
- Fruit formation: After fertilization, the ovary of the flower gradually turns into a fruit.
- Reproduction: After the union of sperm and egg, the ovule of the flower turns into a seed. Most plants on Earth reproduce by seeds. Because of this, female gametophytes play a major role in plant reproduction.
- Formation of new species: Zygote is formed by the union of two different cells sperm and egg. It gives rise to new species with new characteristics.
- Creation of Biodiversity: Eggs are produced in strygametophytes. A zygote is formed by the union of sperm and egg. New species are formed from the zygote. Biodiversity is created through new species.
