    • n embryo The fecundated germ of an animal in its earlier stages of development, and before it has assumed the distinctive form and structure of the parent; a germ; a rudiment; in a more extended sense, a rudimentary animal during its whole antenatal existance. In the later stages of development, especially in man and the mammals generally, the name fetus commonly takes the place of embryology In the cases of oviparous animals, the term embryo properly covers the whole course of development of the fecundated germ in the egg (which see, and see cut under dorsal): as, the hen's egg contained an embryo ready to hatch. By a late and loose, though now common, extension of the term, it is applied to various larval stages of some in vertebrates, which in the course of their transformation are frequently so different from the parent as to be described as distinct species or genera: as, the embryo (first larval stage) of a cestoid worm.
    • n embryo In botany, the rudimentary plant contained in the seed, the result of the action of pollen upon the ovule. It may be so rudimentary as to have apparently no distinction of parts; but even in its simplest form it consists virtually of a single internode of an axis, which upon germination develops at one extremity a leaf or leaves with a terminal bud, and a root at the other. In more developed embryos this initial internode or caulicle (often incorrectly called radicle) bears at one end one, two, or more rudimentary leaves called cotyledons, and often an initial bud or plumnle. Also called germ. By recent authors the term is also applied to the developed oöspore in vascular cryptogams. See cuts under albumen and cotyledon.
    • n embryo The beginning or first state of anything, while yet in a rude and undeveloped condition; the condition of anything which has been conceived but is not yet developed or executed; rudimentary state: chiefly in the phrase in embryo.
    • n embryo Synonyms Fetus, Germ, Rudiment. The first of these words is mainly applied to the embryos of viviparous vertebrates in the later stages of their development, when they are more subject to observation. Germ means especially the seed or fecundated ovum, and scarcely extends beyond the early stages of an embryo. Rudiment is simply the specific application of a more general term to a germ or to the early, crude, or ‘rude’ stages of an embryo.
    • embryo Being in the first or rudimentary stage of growth or development; incipient; embryonic: as, an embryo flower.

  • Interesting fact: There have been several documented cases of women giving birth to twins who had different fathers, including cases where the children were of different races. To do so, the mother had to have conceived both children in close proximity. There has also been one recent case where a mother gave birth to unrelated "twins." In that instance, the mother underwent in vitro fertilization and had her own child and the embryo of another couple accidentally implanted in her.
    • n Embryo em′bri-ō the young of an animal in its earliest stages of development: the part of a seed which forms the future plant: the beginning of anything

A month-old babe upon his mother's breast.

Or sow the embryo of the great,
Must hoard—to wait the ripening hour—
In the least point the loftiest power.

Are whirling around the sun-wanderer's course.

So light imprinted on his forehead fair,
Where Wisdom sits serene

Seems as an embryo empire still were there,
While still his ample breast swells with the vast design.
