Explanation

### Step-by-Step Text Solution:

1. **Understanding C4 Plants**: C4 plants, such as maize and sugarcane, have a unique photosynthetic pathway that allows them to efficiently fix carbon dioxide, especially in hot and dry environments.

2. **Characteristic Anatomical Feature**: The characteristic anatomical feature of C4 plants is known as "Kranz Anatomy." This term refers to the specific arrangement of cells around the vascular bundles in the leaves of these plants.

3. **Structure of Kranz Anatomy**:
- **Bundle Sheath Cells**: In Kranz Anatomy, large cells called bundle sheath cells surround the vascular bundles. These cells are crucial for the C4 photosynthetic pathway.
