Consider the following statement:
A.The layer of bundle sheath cells in the leaves of `C_(4)` plants lacks intercellular spaces-
B. The bundle sheath cells in the leaves of `C_(4)` plants lack mitochondria and peroxisomes.-
C. The bundle sheath cells of `C_(4)` plants have large number of chloroplasts and thick walls.-
Neither `C_(4)` plants nor CAM plants have grana in their chloroplasts and thick walls. -
Which of the statements given above is/are correct?

Options

A. A and B only
B. B and C only
C. A and C only
D. None

Answer

To determine which statements about C4 plants are correct, let's analyze each statement step by step:

### Step 1: Analyze Statement A
**Statement A:** The layer of bundle sheath cells in the leaves of C4 plants lacks intercellular spaces.

- **Explanation:** In C4 plants, the bundle sheath cells are larger and tightly packed, which means they do not have intercellular spaces. This is a characteristic feature of C4 plants, contributing to their efficient photosynthesis process.

**Conclusion:** Statement A is correct.

### Step 2: Analyze Statement B
**Statement B:** The bundle sheath cells in the leaves of C4 plants lack mitochondria and peroxisomes.

- **Explanation:** Bundle sheath cells in C4 plants do contain mitochondria and peroxisomes. These organelles are essential for cellular respiration and other metabolic processes.

**Conclusion:** Statement B is incorrect.

### Step 3: Analyze Statement C
**Statement C:** The bundle sheath cells of C4 plants have a large number of chloroplasts and thick walls.

- **Explanation:** The bundle sheath cells in C4 plants are known to have a large number of chloroplasts, which are larger than those found in other types of plants. Additionally, these cells have thick walls that are gas impermeable, which helps in maintaining the internal environment necessary for photosynthesis.

**Conclusion:** Statement C is correct.

### Step 4: Analyze Statement D
**Statement D:** Neither C4 plants nor CAM plants have grana in their chloroplasts and thick walls.

- **Explanation:** While it is true that C4 plants lack grana in their chloroplasts, they do have thick walls. Therefore, the part of the statement regarding C4 plants is partially true. However, the statement as a whole is misleading because it incorrectly implies that C4 plants do not have thick walls.

**Conclusion:** Statement D is incorrect.

### Final Summary of Statements
- **Correct Statements:** A and C
- **Incorrect Statements:** B and D

### Final Answer
The correct statements are A and C.
