Which of the following is not characteristic bundle sheath cells in Kranz anatomy of leaves?

Options

A. large number of chloroplasts
B. thin walls pervious to gaseous exchange
C. no intercellullar spaces
D. All of the abvoe

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks which of the following options is NOT a characteristic of bundle sheath cells in Kranz anatomy of leaves.

2. **Identify the Characteristics of Bundle Sheath Cells**:
- Bundle sheath cells are specialized cells found in C4 plants, which have a unique leaf anatomy known as Kranz anatomy.
- These cells are known for having a large number of chloroplasts.
- They typically have thick cell walls.
- They are generally impervious to gaseous exchange.
- They usually do not have intracellular spaces.

3. **Analyze the Options**:
- **Large number of chloroplasts**: This is a characteristic of bundle sheath cells.
- **Thin wall**: This is NOT a characteristic of bundle sheath cells; they have thick walls.
- **Pervious to gaseous exchange**: This is also NOT a characteristic; they are impervious to gaseous exchange.
- **No intracellular spaces**: This is a characteristic of bundle sheath cells.
- **All of the above**: This option cannot be correct since some statements are true characteristics.

4. **Determine the Correct Answer**:
- The option that states "thin wall" is NOT a characteristic of bundle sheath cells in Kranz anatomy.

5. **Conclusion**: The answer to the question is "thin wall."
