Sporophyte - Definition, Function and Examples | Biology Dictionary
WebMar 26, 2019 · The basic function of the sporophyte is to create spores – that much is known already. The spores, in turn, produce the gametophytes that give rise to the male and female gametes through the process of meiosis. Meiosis is the type of cell division that reduces the number of chromosomes in half.
