Which one of the following is INCORRECT about root hairs?

Options

  1. AThey are cytoplasmic extensions of epiblema cells.
  2. BThey are unbranched.
  3. CThey are very delicate.
  4. DThey are permanent.

Correct answer

D. They are permanent.

Step-by-step solution

Root hairs are unicellular, unbranched, and delicate tubular extensions of the epiblema (epidermal) cells of the root. They are found in the zone of maturation and are short-lived (ephemeral) structures. As the root grows, older root hairs die and new ones are continuously formed. Therefore, the statement that root hairs are permanent is incorrect. Answer: They are permanent.
