What are the likely functions of these organelles in relation to the sperms' overall functions? AcrosomeNumerous mitochondria(A)Digests through egg membranes for sperm to penetrate.Provide energy for beating action of flagellum.(B)Digests through uterine lining to reach egg.Provide energy for respiration(C)Digests through oviducts to reach egg.Direct overall activities of the sperm.(D)Directs movement of the sperm though the female reproductive tract.

Answer» Correct option (A) Explanation: The egg is surrounded by additional outer membranes, in addition to the cell surface membrane. The acrosomal enzymes serve to break down these membranes to bring about fusion of sperm and egg. The swimming action of the sperm by means of its flagella requires energy that is supplied by numerous mitochondria. |
