Angiosperms (a plant whose ovules are enclosed in an ovary) are commonly referred to as flowering plants, as opposed to Gymnosperms, or cone bearing plants.he difference between an Angiosperm and a Gymnosperm is that Angiosperms are flowering plants while Gymnosperms are not. A. include plants that use flowers to reproduce.
The reproductive structures of angiosperms are formed in specialized and oftenshowy organs called flowers. In contrast to gymnosperms that produce seedsexposed in cones, angiosperms form seeds in an enclosed structure, the ripenedovary or fruit located in the center of the flower.The derivation of angiosperm meansseed in a box or case and is from the Greek words angio meaning box, case, orvessel and sperm meaning seed.ithin the embryo sac, onesperm combines with the egg nucleus to form a zygote and the second spermcombines with two other nuclei, called polar or endosperm nuclei, to form a fertilizedendosperm nucleus that divides mitotically to form endosperm (the nutritive tissue ofangiosperm seeds).
