Young sporophytes of the common moss Tortula muralis. In mosses, the gametophyte is the dominant generation, while the sporophytes consist of sporangium-bearing stalks growing from the tips of the gametophytes. A sporophyte (/spÉËroÊËfaÉªt/) is the diploid multicellular stage in the life cycle of a plant or alga.he sporophyte produces spores (hence the name) by meiosis, a process also known as reduction division that reduces the number of chromosomes in each spore mother cell by half. The resulting meiospores develop into a gametophyte.
