Question

Lenticels are absent in

• A. bark of old stem
• B. pericarp of woody fruits
• C. leaves
• D. roots of dicot flowering plants

Hint:

Lenticels form in the periderm. Think of the plant part that has no periderm.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Lenticels are lens-shaped pores in the periderm that allow gas exchange. They form from the phellogen during secondary growth.

Step 2: Where they occur
They are found in the bark of old stems, in roots of dicots with secondary growth, and on the pericarp of some woody fruits.

Step 3: Conclusion
Leaves have no periderm and exchange gases through stomata, so lenticels are absent in leaves.

Final Answer:
Lenticels are absent in leaves. \[ \boxed{\text{(C) }\text{leaves}} \]
