Question

Quizplus · Accepted Answer

The ovum is indeed larger than the sperm, but the reason is not just because it needs to supply nutrients to the embryo. The ovum also contains all the genetic material needed for the embryo's development, while the sperm only contributes half of the genetic material. Additionally, the size difference between the ovum and sperm is related to the difference in their function - the sperm must be small and motile in order to travel to and fertilize the ovum, while the ovum needs to be large enough to accommodate the developing embryo until it reaches the uterus.
