Meiosis The process of meiosis produces gametes or sex cells. While some parts of this cell division process are similar to the asexual cell division process of mitosis, there are several key differences.Meiosis produces gametes, while mitosis produces other cell types.The process of meiosis halves the chromosome number from the original parent cell in the four cells it forms. It does this by having two cell divisions forming four cells, where mitosis has only one cell division forming two cells.eiosis The process of meiosis produces gametes or sex cells.

The gametophyte is the gamete-producing plant that produces male reproductive structures called antheridia, which produce sperm, and female reproductive structures called archegonia, which produce eggs. When a sperm cell fertilizes an egg inside the archegonium, a diploid zygote is formed.s the spore germinates, it develops into a thin, filamentous stage called a protonema. As the protonema grows, it develops into a mature gametophyte with root-like rhizoids that anchor the plant and an erect, stem-like structure with whorls of leaf-like photosynthetic tissues.
