Read the following statements regarding the structure of a mature human sperm and select the incorrect one.

Options

  1. AThe middle piece possesses numerous mitochondria, which produce energy for the movement of the tail.
  2. BThe acrosome is a cap-like structure filled with enzymes that help in fertilization of the ovum.
  3. CThe sperm head contains an elongated diploid nucleus that carries the genetic material.
  4. DThe tail facilitates sperm motility which is essential for fertilization.

Correct answer

C. The sperm head contains an elongated diploid nucleus that carries the genetic material.

Step-by-step solution
