Gametophyte dependent on sporophyte
WebThe sporophyte is attached to and dependent on the gametophyte. (By “dominated” we mean “the stage of the plant you can see by eye.”) In seedless vascular plants (ferns), the sporophyte is larger than the gametophyte (the plant structure that you see is the sporophyte), but the gametophyte is free-living and independent from the diploid … The resulting meiospores develop into a gametophyte. Both the spores and the resulting gametophyte are haploid, meaning they only have one set of chromosomes. The mature gametophyte produces male or female gametes (or both) by mitosis. The fusion of male and female gametes produces a … See more A sporophyte is the diploid multicellular stage in the life cycle of a plant or alga which produces asexual spores. This stage alternates with a multicellular haploid gametophyte phase.

WebThe gametophyte is a stage in the life cycle that is found in all plants and certain species of algae. 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’.
