Sperm and ovum are the gametes produced by vertebrates. More specifically, sperm is the male gamete while the ovum is the female gamete. These two cells also have contrasting size – for instance, the sperm is the smallest cell in the human body while the ovum is the largest. Read on to explore more differences between the two.
