Five derived traits of seed plants
WebAlternation of generations describes a life cycle in which an organism has both haploid and diploid multicellular stages (Figure 1). This type of life cycle, which is found in all plants, is described as haplodiplontic. Figure 1. Alternation of generations between the 1 n gametophyte and 2 n sporophyte is shown.
