What is an example of a gametophyte?

The fern you imagine when you think of Jurassic Park or a forest floor is a gametophyte. The graceful, fringed leaves are haploid – meaning they have only one set of chromosomes and produce sex cells through mitosis, like all gametophyte plants.

Are seeds haploid or diploid?

The seeds produced by the sporophyte contain: A seed coat of diploid tissue from the original diploid parent. A developing diploid embryo inside which began as a zygote after fertilization of the haploid egg by a haploid sperm. The sperm is likely to have come from a different plant.

What is the function of Gametophyte?

A major function of the gametophyte generation is to produce haploid gametes. Fusion of the egg cell with the sperm cell gives rise to the sporophyte, thereby completing the life cycle (Raven et al., 1992). In many lower plants, gametophytes are the dominant and free-living generation.

What is the function of Sporophyte?

A sporophyte is a multicellular diploid generation found in plants and algae that undergo alternation of generations. It produces haploid spores that develop into a gametophyte. The gametophyte then makes gametes that fuse and grow into a sporophyte. In many plants, the sporophyte generation is the dominant generation.

What are the two types of Gametophytes?

These spores develop into two distinct types of gametophytes; one type produces sperm and the other produces eggs. The male gametophyte develops reproductive organs called antheridia (produce sperm) and the female gametophyte develops archegonia (produce eggs).
