Select the incorrect statement as far as Kranz anatomy is concerned.

Options

A. (a) Undifferentiated mesophyll cells occur in concentric layers around vascular bundles.
B. (b) Centrifugal chloroplasts are present in bundle sheath cells.
C. (c) Large sized bundle sheath cells are arranged in a wreath-like manner in one to several layers.
D. (d) Chloroplasts of bundle sheath cells possess well developed grana lamellae.

Explanation

To solve the question regarding Kranz anatomy and identify the incorrect statement, we will analyze each of the provided statements one by one.

### Step-by-Step Solution:

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

2. **Analyzing the Statements**:
- **Statement 1**: "Undifferentiated mesophyll cells occur in concentric layers around the vascular bundles."
- This statement is **correct**. In Kranz anatomy, mesophyll cells are indeed undifferentiated and arranged in concentric layers around the vascular bundles.

- **Statement 2**: "Centrifugal chloroplasts are present in bundle sheath cells."
- This statement is **correct**. The bundle sheath cells contain smaller, centrifugal chloroplasts that are adapted for their function.

- **Statement 3**: "Large sized bundle sheath cells are arranged in a wreath-like manner in one or several layers."
- This statement is **correct**. The bundle sheath cells are large and arranged in a wreath-like formation around the vascular bundles.

- **Statement 4**: "Chloroplast of bundle sheath cells possesses well-developed grana laminae."
- This statement is **incorrect**. The chloroplasts in bundle sheath cells are agranular, meaning they lack well-developed grana.

3. **Conclusion**:
- The incorrect statement regarding Kranz anatomy is **Statement 4**. Therefore, the correct answer is **Option D**.

### Final Answer:
The correct answer is **Option D**: "Chloroplast of bundle sheath cells possesses well-developed grana laminae."
