Agranal chloroplasts are found in the
(a) Mesophyll of pea leaves
(b) Bundle sheath of mango leaves
(c) Mesophyll of maize leaves
(d) Bundle sheath of sugarcane leaves

Options

A. Mesophyll of pea leaves
B. Bundle sheath of mango leaves
C. Mesophyll of maize leaves
D. Bundle sheath of sugarcane leaves

Answer

To determine where agranal chloroplasts are found, we need to analyze the options given in the question:

1. **Understanding Agranal Chloroplasts**: Agranal chloroplasts are a type of chloroplast that lack thylakoid granules. They are typically found in C4 plants, which have a specific structure and function in photosynthesis.

2. **Identifying C4 Plants**: C4 plants are known for their unique photosynthetic pathway and specialized anatomy called Kranz anatomy. This anatomy features bundle sheath cells that contain agranal chloroplasts.

3. **Evaluating Each Option**:
- **(a) Mesophyll of pea leaves**: Pea plants are C3 plants, not C4, so they do not have agranal chloroplasts.
- **(b) Bundle sheath of mango leaves**: Mango is also a C3 plant, so it does not contain agranal chloroplasts.
- **(c) Mesophyll of maize leaves**: Maize is a C4 plant, but agranal chloroplasts are located in the bundle sheath cells, not in the mesophyll.
- **(d) Bundle sheath of sugarcane leaves**: Sugarcane is a C4 plant, and agranal chloroplasts are indeed found in the bundle sheath cells.

4. **Conclusion**: Based on the analysis, the correct answer is **(d) Bundle sheath of sugarcane leaves**.

### Step-by-Step Solution:
1. Identify the type of chloroplast in question: agranal chloroplasts.
2. Understand that agranal chloroplasts are characteristic of C4 plants.
3. Evaluate each option to see if it corresponds to a C4 plant and the location of agranal chloroplasts.
4. Conclude that agranal chloroplasts are found in the bundle sheath cells of C4 plants, specifically in sugarcane.
