In animals, egg cells are also known as ova (singular ovum, from the latin word ovum meaning egg). The term ovule in animals is used for the young ovum of an animal. In vertebrates, ova are produced by female gonads (sexual glands) called ovaries. A number of ova are present at birth in mammals and mature via oogenesis. Disproved the longstanding dogma that all of the ova are produced before birth. ) the female reproductive or germ cell which after fertilization is capable of developing into a new member of the same species called also egg. The term is sometimes applied to any stage of the fertilized germ cell during cleavage and even until hatching or birth of the new individual. One of a pair of female organs (gonads) on each side of the pelvis.   to put this into perspective, an egg is about 4 times bigger than a skin cell, 26 times bigger than a red blood cell, and 16 times bigger than a sperm! Most eggs are present within the ovary in an immature state from the time of a womans menarche.   an egg is mature after it has undergone two separate rounds of meiosis or cell division. These rounds of cell division reduce the number of chromosomes in the nucleus of the egg from 46 chromosomes to 23 chromosomes in preparation for fertilization by the sperm. 0039 inches in diameter, and contain many proteins and protein precursors. This is because when a sperm cell introduces its genetic information to that of the egg, the egg must respond quickly so that cell division may begin and a new organism may form.

After the release of the mature egg, it is guided by the fimbria into the. When the male sex cell which is the unites with the female sex cell, takes place. The ovary produces the ovum (the egg cell) which is the gametes (sexual reproductive cells) in the animals and the plants. The ovum is large in size because it stores the nutrients, it is produced in few numbers and it is not mobile (static), it contains half the number of chromosomes that are found in female body cells.
