Difference Between Sperm and Ovum

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.
