Agranal chloroplasts are a characerstic feature of one of the following

Options

A. bundle sheath of sugarcane leaves
B. mesophyll of pea leaves
C. bundle sheath of mango leaves
D. mesophyll of maize leaves

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks about the characteristic feature of agranal chloroplasts, specifically which type of plant structure contains them.

2. **Identify Key Terms**: Recognize that "agranal chloroplasts" refer to chloroplasts that do not have thylakoid granules. This is a significant feature in certain types of plants, particularly C4 plants.

3. **Recall C4 Plant Anatomy**: C4 plants exhibit a unique leaf anatomy known as Kranz anatomy. In this structure, bundle sheath cells surround the vascular bundles and are characterized by agranal chloroplasts.

4. **Evaluate the Options**:
- **Bundle Sheaths of Sugarcane Leaves**: Sugarcane is a C4 plant, and its bundle sheath cells contain agranal chloroplasts.
- **Mesophyll of Pea Leaves**: Pea plants are C3 plants, which typically have granal chloroplasts.
- **Bundle Sheaths of Mango Leaves**: Mango is also a C3 plant, which means it does not have agranal chloroplasts in its bundle sheath cells.
- **Mesophyll of Maize Leaves**: Maize is a C4 plant, but the mesophyll cells contain granal chloroplasts, not agranal.

5. **Conclusion**: The correct answer is that agranal chloroplasts are characteristic of the bundle sheaths of sugarcane leaves.

**Final Answer**: Agranal chloroplasts are a characteristic feature of the bundle sheaths of sugarcane leaves.
