Read the following statements regarding the different regions of a typical root and select the incorrect statement.
Options
- AThe root cap is a thimble-like structure that protects the tender apex of the root as it makes its way through
- BThe cells of the region of meristematic activity are large, thick-walled and possess large conspicuous vacuole
- CThe cells of the region of elongation undergo rapid enlargement and are responsible for the growth of the root
- 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. They do not possess large conspicuous vacuoles. The cells proximal to the meristematic region undergo rapid elongation and enlargement, forming the region of elongation, which is responsible for the growth of
