Detailed explanation-1: -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.
Detailed explanation-2: -Most gymnosperms produce seeds in structures called cones or strobili (singular strobilus; Figure 8.1. 2). Cones evolved from modified leaves, and they can either be male cones that produce pollen, or female cones that produce ovules.
Detailed explanation-3: -Gymnosperms. These seed plants do not have flowers or fruit-their seeds are held in cones. Next time you pick up a pine cone, look for loose seeds inside. Male cones make pollen, which is carried to female cones by the wind.
Detailed explanation-4: -Gymnosperms are a relatively small group of plants that do not flower and bear “naked seeds.” This means that the seeds are produced on the surface of the reproductive structure, rather than enclosed within it as in a fruit.
