Question:
Which one of the following is INCORRECT about root hairs?
Which one of the following is INCORRECT about root hairs?
Show Hint
Root hairs live for a short time only.
Updated On: Nov 12, 2026
- They are cytoplasmic extensions of epiblema cells.
- They are unbranched.
- They are very delicate.
- They are permanent.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Root hairs are tubular outgrowths of single epiblema cells. They are unicellular, unbranched and thin-walled.
Step 2: Check each statement
Cytoplasmic extensions of epiblema cells, unbranched and very delicate are all correct.
Step 3: Incorrect one
Root hairs live only a few days. Old hairs die and new ones form behind the growing tip, so they are not permanent.
Final Answer:
The incorrect statement is that root hairs are permanent. \[ \boxed{\text{(D) }\text{They are permanent.}} \]
