Question

a human sperm contains a greater concentration of mitochondria in its cytoplasm than an ovum does. why?

Answer 1

The acrosome in the head contains enzymes so that a sperm can penetrate an egg. The middle piece is packed with mitochondria to release energy needed to swim and fertilise the egg. The tail enables the sperm to swim. Sperm are the smallest cells in the body and millions of them are made.
