O"vum, n.; pl. L. Ova, E. Ovums. Etym: [L., an egg. See Oval.]
1. (Biol.)
Definition: A more or less spherical and transparent mass of granular
protoplasm, which by a process of multiplication and growth develops
into a mass of cells, constituting a new individual like the parent;
an egg, spore, germ, or germ cell. See Illust. of Mycropyle.
Note: The ovum is a typical cell, with a cell wall, cell substance,
nucleus, and nucleolus. In man and the higher animals the cell wall,
a vertically striated membrane, is called the zona pellucida; the
cell contents, the vitellus; the nucleus, the germinal vesicle; and
the nucleolus, the germinal spot. The diameter of the ripe ovum in
man and the domestic animals varies between 1-200 and 1-120 of an
inch.
