A gametophyte is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae. It develops sex organs that produce … See more In some multicellular green algae (Ulva lactuca is one example), red algae and brown algae, sporophytes and gametophytes may be externally indistinguishable (isomorphic).

Gametophyte Structure and Sporophyte Generation
WebThe haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures. Fusion of the male and females gametes forms the diploid zygote, which develops into the sporophyte. WebApr 5, 2024 · Gametophyte reproduction is a type of asexual reproduction in plants, involving the formation of gametes from a single organism. It is a form of alternation of generations, where the sporophyte generation produces haploid spores which grow into the gametophyte generation, which in turn produces the haploid gametes for fertilization. WebMay 10, 2024 · The fusion of the pollen with the female gametophyte produces diploid zygote, which later on divides to form the embryo. Advertisement 406552 Answer: Answer: Gymnosperms produce male cones and female cones, and the pollen from a male cone fertilizes the egg inside a female cone.
