 Reproductive System
Males and females both have organs in their bodies that make sex cells. In males they are called sperm 
cells and in females they are called egg cells. When these two types of sex cells join
together under certain conditions, they produce a zygote. This process is called fertilization and will
normally result in the birth of a child.
