Explanation: 

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: -The word conifer means “cone-bearer, ” a distinct characteristic common to conifers. Cones house the male and female reproductive structures of conifers. Most conifers are monoecious, meaning that both male and female cones can be found on the same tree.

Detailed explanation-3: -Gymnosperms are plants that have seeds but no flowers. The seeds of these plants are on cones or in cups. Most gymnosperms are evergreen. Gymnosperms include conifers, cycads and the ginkgo.

Detailed explanation-4: -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.
