WebThe gametophyte refers to all organs and tissues that are a part of the haploid generation. There are two different developmental stages of the gametophyte: the protonema, and the gametophore. The protonema is the first part of the moss that develops from the germinating spore. Its filamentous form is remarkably similar to green algae.

The sporophyte develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent. All land plants, and most multicellular algae, have life cycles in which a multicellular diploid sporophyte phase alternates with a multicellular haploid gametophyte phase. In the seed plants, the largest groups of which are the gymnosperms and flowering plants (angiosperms), the sporophyt… WebThe sporophyte is differentiated into foot, seta and capsule. It is not the free-living stage, it is dependent on the gametophyte for nourishment. Some of the cells of sporogenous tissue called spore mother cells (diploid) divide meiotically to produce haploid spores. These haploid spores are released by the dehiscence of the capsule. clitoral laceration during delivery icd 10
