Farne gametophyt
WebOverview of Fern Gametophyte. Fern gametophyte is a gametophytic phase in Fern plants which is associated with gamete formation. Ferns exhibit alternations in generations of their life cycle and possess diploid sporophytic and haploid gametophytic stages. The gametophyte is composed of prothallus and rhizoids. WebApr 9, 2024 · The male gametophyte develops and reaches maturity in an immature anther. In a plant’s male reproductive organs, development of pollen takes place in a structure known as the microsporangium (Figure 32.1.5 ). The microsporangia, which are usually bi-lobed, are pollen sacs in which the microspores develop into pollen grains.

This process includes both multicellular diploid generation known as Sporophyte and a multicellular haploid generation known as Gametophyte. The word Diploid refers to two sets of chromosomes in the cells, and normally written as ‘2n’.
