Some species of Angiosperms can also sometimes reproduce asexually, by producing offsets, suckers, bulblets or plantlets. Gymnosperms reproduce by producing male and female cones (male and female sex cells) and after pollination seeds.heir seeds develop without a protective covering of ovary wall. Conifers (like pines, redwoods, and fir), gingkos, seed ferns, cycadeoids, and cycads are gymnosperms. Angiosperms have to undergo a process called pollination before they can reproduce. Angiosperms have male sex organs called stamens.
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).
