Agranal chloroplast occur is

Options

A. Succulents
B. `C_4` plants
C. Hydrophytes
D. `C_3` plants

Answer

### Step-by-Step Solution:

1. **Understanding A Granule Chloroplast**:
- A granule chloroplast is a type of chloroplast that lacks granules (thylakoids). Granules are typically present in most chloroplasts and are essential for the light-dependent reactions of photosynthesis.

2. **Identifying the Types of Plants**:
- The question provides four options: succulents, C4 plants, hydrophytes, and C3 plants. We need to determine which of these types of plants contain a granule chloroplast.

3. **Analyzing Each Option**:
- **Succulents**: These are drought-resistant plants with thick, fleshy leaves. They typically have granule chloroplasts, so this option is incorrect.
- **C4 Plants**: These plants perform the C4 cycle (also known as the Hatch-Slack pathway) and are characterized by having dimorphic chloroplasts. The bundle sheath cells in C4 plants lack granules, making this option correct.
- **Hydrophytes**: These are aquatic plants that also contain granule chloroplasts, so this option is incorrect.
- **C3 Plants**: These plants perform the Calvin cycle (C3 cycle) and have granule chloroplasts, so this option is also incorrect.

4. **Conclusion**:
- The correct answer is **C4 plants**, as they are the only type of plants listed that contain a granule chloroplast.

### Final Answer:
**C4 plants**
