Detailed explanation-1: -Gymnosperms are seed-producing plants but they do not bear flowers. Phanerogams consist of both angiosperms and gymnosperms. Pteridophytes neither produce seeds nor flowers.

Detailed explanation-2: -Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers. Both groups use pollen to facilitate fertilization, though angiosperms have an incredible diversity of pollination strategies that are not found among the gymnosperms.

Detailed explanation-3: -Non-flowering plants include mosses, liverworts, hornworts, lycophytes and ferns and reproduce by spores. Some non-flowering plants, called gymnosperms or conifers, still produce seeds.

Detailed explanation-4: -Angiosperms, are also known as flowering plants and having seeds enclosed within their fruit. Whereas gymnosperms have no flowers or fruits and have naked seeds on the surface of their leaves.

Detailed explanation-5: -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.
