AP BIOLOGY

Detailed explanation-1: -The flowering plants that bear seed but no fruits are called gymnosperms. Their seeds are thin and naked, not enclosed in fruits. Most gymnosperms are evergreen i.e. they do not shed all their leaves at one time. Some examples are pine, fir, cedar and spruce trees that grow in mountainous areas.

Detailed explanation-2: -Gymnosperms are a smaller, more ancient group, and it consists of plants that produce “naked seeds” (seeds that are not protected by a fruit).

Detailed explanation-3: -Division I – (Gymnosperms) Seeds from these plants do not have any natural coverings. They do not produce fruits and so the name (gymnos: naked, sperms: seeds).

Detailed explanation-4: -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-5: -The word “Gymnosperm” comes from the Greek words “gymnos”(naked) and “sperma”(seed), hence known as “Naked seeds.” Gymnosperms are the seed-producing plants, but unlike angiosperms, they produce seeds without fruits.
