An ovum, also known as an egg cell, is the female reproductive cell produced by the ovaries. It is a large, spherical cell that contains nutrients and genetic material necessary for fertilization and the development of a new organism.
During sexual reproduction, an ovum is released from an ovary and travels through the fallopian tube where it may be fertilized by a spermatozoon. If fertilization occurs, the ovum undergoes cell division and eventually develops into a fetus.
