Kranz anatomy is not exhibited by which of the following plants?

Options

A. Maize
B. Sorghum
C. Sugarcane
D. Sunflower

Explanation

To determine which plant does not exhibit Kranz anatomy, we need to understand what Kranz anatomy is and which types of plants possess it.

### Step-by-Step Solution:

1. **Understanding Kranz Anatomy**:
- Kranz anatomy is a specialized structure found in C4 plants. It involves a unique arrangement of bundle sheath cells and mesophyll cells. The bundle sheath cells are arranged in a wreath-like manner around the vascular bundles.

2. **Identifying C4 Plants**:
- C4 plants are known for their efficient photosynthesis process, which minimizes photorespiration. Common examples of C4 plants include maize (corn), sorghum, and sugarcane. These plants have adaptations that allow them to thrive in high light and temperature conditions.

3. **Analyzing the Options**:
- **Maize**: This is a C4 plant and exhibits Kranz anatomy.
- **Sorghum**: This is also a C4 plant and exhibits Kranz anatomy.
- **Sugarcane**: This is another C4 plant that exhibits Kranz anatomy.
- **Sunflower**: This plant is a C3 plant and does not exhibit Kranz anatomy.

4. **Conclusion**:
- Since Kranz anatomy is characteristic of C4 plants, and sunflower is a C3 plant, the correct answer to the question is **sunflower**.

### Final Answer:
The plant that does not exhibit Kranz anatomy is **sunflower**.
