Gametophyte plant body
WebPlants show alternation of generation between a gametophytic and a sporophytic body. The gametophytic body can be either male or female. These are haploid structures which produce gametes. The gametes fuse to form a zygote and give rise to a diploid sporophytic body. Let us look at their differences: WebExternal structure of gametophyte.
