(oh´ eh go´ nee um) • In some algae and fungi, a cell in which an egg is produced.
The earliest recognisable form of the ovum, or egg; present only in the ovaries of fetuses. Multiplies by the process of mitosis before developing into oocytes by the process of meiosis. The male equivalent (the spermatogonium) normally persists in the testicles till old age. Plural, oogonia.
(Gr. ôon: egg; gonos: generation) n. (pl. oogonia) The female sexual organ in Carophytes, of algae and fungi.
A unicellular structure in algae in which eggs are produced.
In fungi, the female reproductive structure of such oomycetes as Pythium spp. and Phytophthora spp. containing one or more gametes.
A female reproductive structure capable of producing one or more eggs
oo-GO-nee-um The diploid cell where egg formation begins. 204, 464
A unicellular gametangium that contains an egg.
(pl. Oogonia) - Female egg cell of oomycete fungi.
In algae, a female reproductive cell producing one or more eggs.
Gr. oon - an egg; Gr. gone - seed] Germ cell in the ovary that gives rise to oocytes through repeated mitotic divisions.
bisc333 A female ancestral germ cell that divides several times to give rise to an oocyte that, in turn, develops into an ovum (an egg). http://www.medterms.com/script/main/art.asp?articlekey=4642
An oogonium (plural oogonia) is a female gametogonium. They are formed in large numbers by mitosis early in fetal life from primordial germ cells. Once in the ovary, they divide by mitosis into two primary oocytes; it is important to note that this process is complete before birth, in contrast to spermatogenesis.
