Specialized epidermal cells surrounding the guard cells are:
Specialized epidermal cells surrounding the guard cells are:
Show Hint
Subsidiary cells assist guard cells in regulating stomatal opening.
Updated On: Mar 17, 2025
- Complementary cells
- Subsidiary cells
- Bulliform cells
- Lenticels
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Stomatal Complex
- Guard cells regulate stomatal opening and closing.
- Subsidiary cells are specialized epidermal cells that provide support to guard cells.
Step 2: Identifying the Correct Answer
- Complementary cells (Incorrect – Part of lenticels).
- Subsidiary cells (Correct – Provide support to guard cells).
- Bulliform cells (Incorrect – Involved in leaf rolling).
- Lenticels (Incorrect – Gas exchange structures in woody plants).
