Reproduction in Nonvascular Plants ï Nonvascular plants have a life cycle called alternation of generations. â¢ A gamete-producing stage (gametophyte) alternates with a spore-producing stage (sporophyte).â¢ Gametophytes produce gametes (eggs and sperm) in separate multicellular structures.eproductive Structures of Seed Plants ï Reproduction in seed plants (gymnosperms and angiosperms) is very different from reproduction in seedless plants. ï You need a microscope to see the gametophytes of seed plants. ï Spores are not released from seed plants.
Microspores (produced in a microsporangium) can develop into male gametophytes that produce sperm within antheridia. Because the gametophytes develop within the spores, they are not free-living as the gametophytes of other seedless vascular plants.s the spore germinates, it develops into a thin, filamentous stage called a protonema. As the protonema grows, it develops into a mature gametophyte with root-like rhizoids that anchor the plant and an erect, stem-like structure with whorls of leaf-like photosynthetic tissues.
