WebJan 25, 2024 · The gametophyte is the haploid stage of the plant, which produces haploid gametes by the process of mitosis; hence it is called gametophyte. Sporophytes are diploid stages of plants that produce haploid meiospores by meiosis. They receive nourishment from the gametophytes and produce haploid meiospores.
