Which one of the following is INCORRECT about root hairs?
Which one of the following is INCORRECT about root hairs?
Options
- AThey are cytoplasmic extensions of epiblema cells.
- BThey are unbranched.
- CThey are very delicate.
- 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.
