In `C_(4)`-plants, photosystem II is absent in chloroplasts of

Options

A. Mesophyll cells
B. Bundle sheath cells
C. Palisade cells
D. Spongy cells.

Answer

**Step-by-Step Solution:**

1. **Understand the Types of Cells in C4 Plants**: C4 plants have two main types of photosynthetic cells: mesophyll cells and bundle sheath cells.

2. **Identify the Role of Chloroplasts**: In C4 plants, chloroplasts are present in both types of cells, but they have different functions. Mesophyll cells are responsible for the initial fixation of carbon dioxide, while bundle sheath cells are involved in the Calvin cycle.

3. **Determine the Presence of Photosystem II**: Photosystem II is a crucial component of the photosynthetic process. In C4 plants, it is specifically absent in the chloroplasts of bundle sheath cells.

4. **Conclude the Answer**: Since the question asks where Photosystem II is absent, the correct answer is that it is absent in the chloroplasts of bundle sheath cells.

**Final Answer**: Photosystem II is absent in the chloroplasts of bundle sheath cells in C4 plants.
