Chapter 31.2, Problem 4SAQ
Summary Introduction
Each plant species alternates among two multicellular forms, which includes a haploid gametophyte generation (makes gametes) and a diploid sporophyte generation (makes spores). The gametophyte generation starts with a haploid spore, which is generated by meiosis. The gametophyte generates gametes by mitosis and sexual reproduction. This resulting in diploid sporophyte generation.
