In biology, '''sex''' refers to the categorization of organisms (or their parts) with regard to the role they play in reproduction. When a species reproduces sexually, it usually does so by producing one of two types of gamete that have to come together to form a new member of the species. One type of gamete is large and non-mobile (ova), whereas the other type is small and motile (sperm). When an organism or an organ produces large and non-mobile gametes, it is called '''female'''. If it produces small and motile gametes, it is called '''male'''. | In biology, '''sex''' refers to the categorization of organisms (or their parts) with regard to the role they play in reproduction.
