Natttre of Seeds.—Seeds are embryo plants, the mature, fecundated ovule, with Fig 31- certain nutritive properties stored up withm various protective organs. A seed is also a living organism which separates from its parent, and is then capable of becoming a new individual of the same species. When mature they contain various albuminous, ligne- ous and oily compounds required to supply the young plantlet with nutriment during its early stages of growth, or until roots are produced through which it can obtain nutri- ents from surrounding elements. Some seeds acquire a stony hard- ness when npe, as seen in the Ivory Nut; others remain soft and fleshy, as in the Horse- chestnut, or partly fleshy and partly liquid, as in the Cocoanut; others, like those of the maples and elms, are soft, and the cotyledons leaf-like; others are of a starchy nature, as in Oats, Buckwheat and the Onion. Seeds are usually enclosed in a peri- carp or seed-vessel, which offers protec- tion to the kernel and germ. Some- times there are several of these protective organs, as seen. Fig. 32. Q. p.
