Question

Nerve cells do not divide as they lack

• A. Nucleus
• B. Golgi body
• C. Mitochondria
• D. Centrosome

Answer 1

The correct option is D Centrosome

• Centrosomes are key to the division of cells and produce the spindle fibres that are required during metaphase of mitosis.
• Each centrosome consists of two centrioles that are orientated at right angles to each other.
• Nerve cells are not able to multiply because they lack centrioles as they can not participate in mitosis and meiosis activity but still they get longer without dividing during childhood.
• It occurs due to synpatic or axon pruning . Unlike other types of cells, neurons do not divide in their life time. Hence, Nerve cells do not divide as they lack centrosomes.

So, the correct answer is 'centrosomes'.
