Coleorhiza :: Coleorhiza (n.) A sheath in the embryo of grasses, inclosing the caulicle..

Gastrula :: Gastrula (n.) An embryonic form having its origin in the invagination or pushing in of the wall of the planula or blastula (the blastosphere) on one side, thus giving rise to a double-walled sac, with one opening or mouth (the blastopore) which leads into the cavity (the archenteron) lined by the inner wall (the hypoblast). See Illust. under Invagination. In a more general sense, an ideal stage in embryonic development. See Gastraea..

Parthenogenesis :: Parthenogenesis (n.) The production of seed without fertilization, believed to occur through the nonsexual formation of an embryo extraneous to the embrionic vesicle..

Suspensoria :: Suspensor (n.) The cord which suspends the embryo; and which is attached to the radicle in the young state; the proembryo.

Archenteron :: Archenteron (n.) The primitive enteron or undifferentiated digestive sac of a gastrula or other embryo. See Illust. under Invagination.

Embryologist :: Embryologist (n.) One skilled in embryology.

Mesonephros :: Mesonephros (n.) The middle one of the three pairs of embryonic renal organs developed in most vertebrates; the Wolffian body.

Metamorphosis :: Metamorphosis (n.) A change in the form or function of a living organism, by a natural process of growth or development; as, the metamorphosis of the yolk into the embryo, of a tadpole into a frog, or of a bud into a blossom. Especially, that form of sexual reproduction in which an embryo undergoes a series of marked changes of external form, as the chrysalis stage, pupa stage, etc., in insects. In these intermediate stages sexual reproduction is usually impossible, but they ultimately pass into

Wolffian :: Wolffian (a.) Discovered, or first described, by Caspar Friedrich Wolff (1733-1794), the founder of modern embryology..

Pseudofilaria :: Pseudofilaria (n.) One of the two elongated vibratile young formed by fission of the embryo during the development of certain Gregarinae.

Myotome :: Myotome (n.) One of the embryonic muscular segments arising from the protovertebrae; also, one of the protovertebrae themselves..

Germogen :: Germogen (n.) The primitive cell in certain embryonic forms.

Metanephros :: Metanephros (n.) The most posterior of the three pairs of embryonic renal organs developed in many vertebrates.

Polyembryony :: Polyembryony (n.) The production of two or more embryos in one seed, due either to the existence and fertilization of more than one embryonic sac or to the origination of embryos outside of the embryonic sac..

Endogen :: Endogen (n.) A plant which increases in size by internal growth and elongation at the summit, having the wood in the form of bundles or threads, irregularly distributed throughout the whole diameter, not forming annual layers, and with no distinct pith. The leaves of the endogens have, usually, parallel veins, their flowers are mostly in three, or some multiple of three, parts, and their embryos have but a single cotyledon, with the first leaves alternate. The endogens constitute one of the grea

Pseudembryo :: Pseudembryo (n.) An asexual form from which the true embryo is produced by budding.

Diphygenic :: Diphygenic (a.) Having two modes of embryonic development.

Proembryo :: Proembryo (n.) The primary growth from the spore in certain cryptogamous plants; as, the proembryo, or protonema, of mosses..

Hyaline :: Hyaline (n.) The pellucid substance, present in cells in process of development, from which, according to some embryologists, the cell nucleous originates..

Protovertebra :: Protovertebra (n.) One of the primitive masses, or segments, into which the mesoblast of the vertebrate embryo breaks up on either side of the anterior part of the notochord; a mesoblastic, or protovertebral, somite. See Illust. of Ectoderm..
