Define reproductive cell. reproductive cell synonyms, reproductive cell pronunciation, reproductive cell translation, English dictionary definition of reproductive cell. A cell whose nucleus unites with that of a cell of the opposite sex to form a new organism. A reproductive cell contains only a single (haploid) set of chromosomes. Animal egg and sperm cells, the nuclei in grains of pollen, and egg cells in plant ovules are all reproductive cells. Also called gamete, sex cell. See Note at mitosis.
A sperm cell is the male sex cell. All animals (and many other types of organisms) produce what are called sex cells. Sex cells are the cells, that when combined, produce a completely new organism. For example, your mother and every other human female, carry egg cells (female sex cells) in their ovaries. Your father and every other human male carry sperm cells, or male sex cells, in their testes. When an egg cell and a sperm cell unite, the two combine to form an embryo or an unborn, developing organism. At this point, the embryo is able to develop into a fully formed offspring of its parents.
