Sexual Reproduction in Gymnosperms | Biology for Majors II
网页Identify the structures involved in reproduction of gymnosperms. As with angiosperms, the lifecycle of a gymnosperm is also characterized by alternation of generations. In conifers such as pines, the green leafy part of the plant is the sporophyte, and the cones contain the male and female gametophytes (Figure 1).

网页2024年8月31日 · gymnosperm, any vascular plant that reproduces by means of an exposed seed, or ovule —unlike angiosperms, or flowering plants, whose seeds are enclosed by mature ovaries, or fruits. The seeds of many gymnosperms (literally, “naked seeds”) are borne in cones and are not visible until maturity.

网页Among the numerous other gymnosperm species are many different reproductive processes. Some gymnosperms, for example, are dioecious, with microstrobili and megastrobili being borne on separate plants, as in junipers (Juniperus), plum yews (Cephalotaxus), yews (Taxus), and podocarps (Podocarpus).
网页Gymnosperms (literally “naked seed”) are vascular plants that reproduce by means of an exposed seed, or ovule. Unlike true flowering plants (angiosperms), whose ovules are sheltered inside closed ovaries, the ovules of gymnosperms are borne on open bracts, commonly arranged in cones, or “strobili.”

网页Male and female sporangia are produced either on the same plant, described as monoecious (“one home” or bisexual), or on separate plants, referred to as dioecious (“two homes” or unisexual) plants. The life cycle of a conifer will serve as our example of reproduction in gymnosperms.
