(A seed (/ delete information help · ː d)), some food is usually stored in a small embryonic plant cover are called seed coating. Gymnosperm and fertilization and their mothers in these plants occur after some growth of the mature egg cell is a product of angiosperm plants. seed formation), zygotes and embryos from egg cells, integuments and seed coat and seed plants developed (producing flowers and worked with the development process of fertilization of the whole.

Seed production and propagation of flowering plants, mosses than the more primitive plants, ferns and liverworts, are no seeds and use them in other ways has been an important development. Control of seed plants in this soil biological niches (both gymnosperms and Angiosperms) success, forests and pastures can be seen both hot and cold climates.
The term seed also above - sown ie "seed" potatoes, corn or sunflower "seed" seed "can be nothing prior to a general sense there is. Sunflower and maize in case of" seeds ", what planted the seeds or the inside of the boat and one potato a tuber was .

A typical seed includes three basic parts: (1) an embryo, (2) a source of nutrients for the embryo, and (3) a seed coat.
Embryo, a new plant which will grow in appropriate conditions is an immature plant. An embryo, cotyledon, or seed leaves are monocotyledons, gymnosperms, almost all dicotyledons and two or more than two cotyledons. Embryonic stem radicle. Plumule embryonic taken. cotyledon (s attachment point on the embryonic stem) is the epicotyl. Attachment points below that of embryonic stem hypocotyl.
In seeds, typically from the embryos to grow seedlings for the food store. stored depends on the type of diet plants. endosperm tissue, which is derived from plants called mother by double fertilization in Angiosperms stored food begins. Usually triploid endosperm is rich in oil or starch and protein. In gymnosperms, conifers, such as food storage tissue is part female gametophyte, is haploid tissue. In some species, the female embryo, endosperm, or buried, which will be used on seedling germination gametophyte. In others, endosperm second seed in the developing embryo is absorbed by the cotyledons and the embryo as it grows full of stored food. Maturity, and seeds of these species have no endosperm is called exalbuminous seed. Exalbuminous seeds of some beans, peas, oak, walnut, pumpkin, sunflower and radish are. Seeds with an endosperm at maturity the seeds are albuminous. Most Monocots (eg grasses and palms) and many dicots (Brazil nuts, the wheel, such as beans) have albuminous seeds. All gymnosperm seeds are albuminous.
Seed coat (or Testa) developed tissue, skin, beginning around the ovum. paper-thin layer coating the seeds mature seeds (eg peanut) or something else (for example, may have large and important honey locust and coconut). Seed coating to protect the embryo against mechanical injury and helps to dry.
three basic seed, as well as some seeds), one (as Corydalis) or feathers (such as cotton elaiosome yew and nutmeg) or as seed coating a tegument (an extension there. Moreover, seed coat over the scar, Hilum be called and he Where seed is to be connected with the ovary wall cord.
