Question

Given below are certain statements regarding sperm organelles. With respect to these statements, choose the correct option.

Statement 1: Centrioles provide polarity to the sperm.

Statement 2: Centrioles release energy when mitochondria in sperm become dysfunctional.

Statement 3: Centrioles help in cell division in the zygote formed post fertilisation.

Statement 4: Sperm do not possess centrioles.

• A. Statement 1 is correct.
• B. Statements 1 and 2 are correct.
• C. Statements 1, 3 and 4 are correct.
• D. Statement 3 is correct.

Answer 1

The correct option is D

Statement 3 is correct.

Centrioles are cell organelles which are responsible for the process of cell division. Sperms do not undergo further cell division. However, when sperm fuses with the ovum forming the zygote, it divides mitotically utilising the centrioles of the sperm, as the ovum is devoid of centrioles.
