have a life cycle that alternates generations

Answer 1

The right answer is "have a life cycle that alternates generations"

The alternation of generations (metagenesis) is a characteristic of plants' life cycle. A generation is a stage of multicellular development stemming from a cellular stage (spore or gamete) and producing a cellular stage (gamete or spore). The generation producing gametes is the gametophyte, and the generation producing spores is the sporophyte. In general, a gametophyte alternates with a sporophyte. When mature, the sporophyte produces spores.
