a mature female germ cell which, only after fertilization, develops into a zygote and then a fetus.
A mature reproductive cell of female animals.
(pl. ova) A functional egg cell of an animal, produced by gametogenesis. Ova are frequently packed with nutritive yolk granules and are usually immobile.
An ovum is an egg that exists in the ovary of the female. This egg is called the female "gamete" or sex cell. It combines with the male gamete, called a sperm, to form a zygote. This formation process is called "fertilization." See sperm, zygote.
The egg or reproductive cell from the ovary. This sex cell contains the female's genetic information. PCO – Poly Cystic Ovaries A term that describes ovaries that contain lots of little follicles.
The female reproductive cell, also called the egg.
a mature egg cell formed in the second meiotic division of the secondary oocyte; the larger of the two formed cells rapidly matures into an ovum.
The reproductive cell from the ovary that contains the woman's genetic information.
The egg produced by the ovary.
pl. ova( oh-vum) [L. egg] The female gamete; the haploid, unfertilized egg, which is usually a relatively large, nonmotile cell.
female reproductive cell or egg, plural - ova.
An egg cell. close window
a female gamete or egg, also called an oocyte.
a mature egg that is ready for fertilization.
another term for an egg cell
the female germ cell; also a generic term for the female egg or conceptus for about 2 weeks after fertilization prior to the development of the embryo, in which case it is described as the fertilized ovum, the blastomeric ovum, the three-chambered ovum, etc.
An egg or ovum is a female reproductive cell produced by the ovaries. After fertilisation by a sperm (a male reproductive cell), the two cells fuse together to form a single cell, from which an embryo develops.
the human female reproductive cell.
Another name for the egg.
Egg; the female reproductive element.
An egg, the female germ, or sex, cell produced in the ovaries.
A specialized sexual cell, commonly called the egg or egg cell, of the female, which corresponds to the sperm in males. It is larger than the sperm because of the food material which is contained in it, and it lacks a tail, instead having a smooth round surface. The ovum was discovered by K.E. von Baer and are produced in the female ovaries. Like the sperm, the number of chromosomes are halved before fertilization in a process called meiosis. Once fertilized, the single cell consisting of half the chromosomes of each of the ovum and the sperm is known as the fertilized ovum, or egg.
(noun, plural: ova) - egg.
(oh´ vum) [L.: egg] • The egg, the female sex cell.
The egg cell (gamete) produced in a woman's ovaries during each menstrual cycle.

The egg (reproductive) cell produced in the ovaries each month. (The plural of ovum is ova.)
An egg cell. A female productive cell.
the female reproductive cell, also called an egg. When an ovum joins a sperm, an embryo is produced. Pangea: A huge "supercontinent" that encompassed most of the Earth's crust, 300 to 200 million years ago.
The unfertilized female gamete or sex cell (egg) produced in the ovaries each month, that contains the genetic information to be transmitted by the female.
The female germ cell or true egg; plural form is ova.
The egg; the reproductive cell from the ovary; the female gamete; the sex cell that contains the womans genetic information.
Unfertilised egg-cell containing a haploid nucleus.
The female reproductive cell. Plural form: ova

ovulum - egg]. Mature female gamete or egg cell.
The female sex cell (egg). Plural: ova
An unfertilized egg still within the ovary or oviduct of a female bird.
An egg cell manufactured in an ovary and contributed by the female as part of sexual reproduction.
Egg. The female gametocyte that develops in the follicle of the ovarv.
Egg or germ cell produced by the female reproductive organ, the ovary.
The female reproductive cell, also known as the egg, which when united with a sperm can become fertile and create life.
The fully mature egg produced from the ovary each month.
the female reproductive or germ cell; an egg cell
an egg cell (female gamete). The largest of the four female gamete cells produced by a single meiotic division, it receives the majority of the cytoplasm and organelles from the parent cell.

Female reproductive cell, the ovum (also known as the egg) is produced by the ovaries. Ova is plural for ovum.
The female gamete or egg cell.
a mature egg cell released during ovulation from an ovary.
The female germ cell, or egg, from the earliest stage (the oogonium in the fetus), through its release from the follicle (ovulation), and (to professional embryologists) through fertilisation up to and sometimes beyond the stage of implantation. Plural: ova. See also: blighted ovum
(pl. ova)- mature but unfertilized egg cell.
An ovum (plural ova) is a haploid female reproductive cell or gamete. The word is derived from Latin, meaning egg or egg cell. Both animals and embryophytes have ova.
