| A '''seed''' is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some [[growth]] within the mother plant. The formation of the seed completes the [[process]] of reproduction in seed plants (started with the [[development]] of flowers and pollination), with the embryo developed from the zygote and the seed coat from the integuments of the ovule. | | A '''seed''' is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food.

− | Seeds have been an important development in the reproduction and spread of flowering plants, [[relative]] to more [[primitive]] plants like [http://en.wikipedia.org/wiki/Moss mosses], [http://en.wikipedia.org/wiki/Ferns ferns] and [http://en.wikipedia.org/wiki/Marchantiophyta liverworts], which do not have seeds and use other means to propagate themselves. This can be seen by the success of seed plants (both gymnosperms and angiosperms) in dominating [[biological]] niches on land, from forests to grasslands both in hot and cold climates. | + | Seeds have been an important development in the reproduction and spread of flowering plants, [[relative]] to more [[primitive]] plants like [https://en.wikipedia.org/wiki/Moss mosses], [https://en.wikipedia.org/wiki/Ferns ferns] and [https://en.wikipedia.org/wiki/Marchantiophyta liverworts], which do not have seeds and use other means to propagate themselves.

− | The term seed also has a general [[meaning]] that predates the above — anything that can be sown i.e. "seed" potatoes, "seeds" of corn or sunflower "seeds". In the case of sunflower and corn "seeds", what is sown is the seed enclosed in a shell or hull, and the potato is a tuber.[http://en.wikipedia.org/wiki/Seed] | + | The term seed also has a general [[meaning]] that predates the above — anything that can be sown i.e. "seed" potatoes, "seeds" of corn or sunflower "seeds".
