Question

Which of the following is absent in plants?

• A. Cell wall
• B. Vascular system
• C. Nervous system
• D. Epidermal tissue system

Answer 1

Answer: (C)

Nervous system

The central nervous system is absent in plants. Even though plants do not have a nervous system, electrical and chemical signalling systems have been identified in plants which are homologous to those found in the nervous systems of animals. They communicate through the change in water pressure and with the help of certain substances.

Thus, the correct answer is option C.
