Mention the exact location of the Lenticels structures

Explanation

### Step-by-Step Solution:

1. **Definition of Lenticels**: Lenticels are small, pore-like structures found on the surface of certain plant organs. They facilitate gas exchange between the internal tissues of the plant and the external environment.
