Choose the correct option for the chloroplast of bundle sheath from the following

Options

A. They show grana organisation
B. They do not show grana organisation
C. They do not possess, thylakoids.
D. They possess thylakoid and grana organisation.

Answer

To solve the question regarding the chloroplasts of bundle sheath cells in C4 plants, we will analyze the options provided and understand the characteristics of chloroplasts in these specific cells.

### Step-by-Step Solution:

1. **Understanding Bundle Sheath Cells**:
- In C4 plants, bundle sheath cells surround the vascular bundles. These cells are specialized for the C4 photosynthetic pathway.

2. **Chloroplast Structure in Bundle Sheath Cells**:
- The chloroplasts in bundle sheath cells are different from those in mesophyll cells. They are larger and have a unique arrangement.

3. **Thylakoid Arrangement**:
- The chloroplasts in bundle sheath cells are characterized by having unstacked thylakoids. This means that they do not form the typical granal stacks found in chloroplasts of mesophyll cells.

4. **Evaluating the Options**:
- **Option 1**: They show grana organization - **Incorrect**. Bundle sheath chloroplasts do not have grana.
- **Option 2**: They do not show grana organization - **Correct**. This accurately describes the chloroplasts in bundle sheath cells.
- **Option 3**: They do not possess thylakoids - **Incorrect**. They do have thylakoids, but they are unstacked.
- **Option 4**: They possess thylakoid and grana organization - **Incorrect**. As mentioned, they do not have grana.

5. **Conclusion**:
- The correct option is that the chloroplasts in bundle sheath cells **do not show grana organization**.

### Final Answer:
The correct option for the chloroplast of bundle sheath cells is: **They do not show grana organization**.
