  2. BThe cells of the region of meristematic activity are large, thick-walled and possess large conspicuous vacuole
  3. CThe cells of the region of elongation undergo rapid enlargement and are responsible for the growth of the root
  4. DThe cells of the elongation zone gradually differentiate and mature to form the region of maturation.

Correct answer

B. The cells of the region of meristematic activity are large, thick-walled and possess large conspicuous vacuole

Step-by-step solution

The root cap is a thimble-like structure that protects the tender apex of the root as it makes its way through the soil. The region of meristematic activity is located a few millimetres above the root cap. The cells of this region are very small, thin-walled, and with dense protoplasm. They divide repeatedly.
