It is called a seed plant, not to be confused with ferns and mosses whose gametes require water for fertilization. Seed plants can be either gymnosperms or angiosperms.Spermatophyte
In pea plants, the eggs are fertilized by pollen. Pollen contains the male gametes (sperm cells) that fertilize the female gametes (egg cells) in the ovule of the flower. This process leads to seed development in pea plants.
Gametophytes of seed plants do not need standing water to function because they produce male and female gametes within protective structures (pollen grains and ovules) that are transferred by wind, insects, or other means for fertilization. This adaptation allows seed plants to reproduce successfully in a variety of environments, not relying on standing water for the fertilization process.
Pollen transfers from the anther to the pistil in plants during the process of pollination. Pollen grains contain male gametes that fertilize the female gametes in the pistil to initiate seed formation.
No , the non seed plants initially dependant on water for transport od gametes .. So, the farn produce spore where spore germinate and grow into gametophyte plant where it contain sperms that is transported by water.
Non-seed plants evolved from seed plants.
In plants, the containers of gametes are called gametangia. Male gametes are produced in antheridia, while female gametes are produced in archegonia. These structures are crucial for reproduction, particularly in non-flowering plants like mosses and ferns, where they facilitate the formation of gametes. In flowering plants, gametes are found within the pollen grains and ovules.
In a seed, it is the sporophyte embryo that is present. The sporophyte is the diploid generation that develops from the fertilization of gametes, while the gametophyte generation is typically reduced and dependent on the sporophyte in seed plants. Thus, the seed contains the developing sporophyte embryo, which will grow into the mature plant.
Pollen grains are carried to female gametes in seed plants by the wind, insects, birds, or other animals. Once the pollen grain reaches the female reproductive structure, such as the stigma, it germinates and forms a pollen tube that grows down to the ovule, allowing for fertilization to occur.
The scientific name for pollen grains is "microgametophytes." These are the male gametophytes in seed plants that produce the male gametes necessary for fertilization.
Pollen in seed plants develops from microspores, which are produced through meiosis in the anthers of flowers. These microspores undergo mitosis to form pollen grains, which contain the male gametes. Pollen is crucial for the reproduction of seed plants, as it facilitates the transfer of sperm to the ovule for fertilization. This process plays a key role in the life cycle of flowering plants and contributes to their genetic diversity.
