... Meiosis converts a diploid cell into haploid cells. Fertilization combines the 2 haploid gamete cells (sperm and egg) back into a diploid cell. Eukaryotes alternate between diploid and haploid stages. This is called the life cycle of the organism. In plants, the haploid cells grow into multicellular ...
