Question

Identify the parts labelled as A, B, C, and E in the given diagram of a human sperm and select the correct option.

• A. A-Nucleus, B-Tail, C-Mitochondria, D-Acrosome, E-Centriole
• B. A-Acrosome, B-Nucleus, C-Centriole, D-Mitochondria, E-Plasma membrane
• C. A-Nudeus, B-Mitochondria, C-Plasma membrane, D-Centriole, E-Neck
• D. A-Acrosome, B-Centriole, C-Mitochondria, D-Plasma membrane, E-Tail

Answer 1

The correct option is B A-Acrosome, B-Nucleus, C-Centriole, D-Mitochondria, E-Plasma membrane

The sperm has an outermost covering as the plasma membrane followed by a cap-like structure called acrosome that covers the anterior part of the sperm head which contains enzymes for the fertilization of the ovum. The neck consists of centriole and the middle piece has numerous mitochondria which produce energy to facilitate movement of the sperm.

So, the correct option is 'A-Acrosome, B-Nucleus, C-Centriole, D-Mitochondria, E-Plasma membrane'.
