- Draw a simple diagram illustrating alternation of generations in plants, including the sporophyte and gametophyte generations, spores, gametes (eggs and sperm), meiosis, and fertilization. Be sure to indicate whether each generation or kind of cell is haploid or diploid.The three illustrations represent the three types of relationships between the haploid gametophyte and diploid sporophyte generations found among plants. Identify the types of plants and the characteristics that belong with each of the three types of relationships. Bryophyte Ferns Seed plants ferns and horsetails mosses, liverworts, and other bryophytes Ginko biloba, spruce trees, and other gymnosperms The gametophyte requires nourishment from the sporophyte in order to survive. The sporophyte and gametophyte generations grow independently and produce differently shaped plants. The sporophyte cannot survive without nourishment from the gametophyte.
