Why is a large number of sperm needed to ensure that fertilization occurs?
What will be an ideal response?
Many sperm are needed for fertilization for two reasons. First, not all sperm are hardy enough to make the long trip to the oviduct where the egg is. Therefore, a large number of sperm are needed to ensure that some sperm reach the right destination. Second, even though only one sperm penetrates and fertilizes the egg, many sperm are needed to swarm around the egg and secrete an enzyme that loosens the cells surrounding the egg.
