Dimorphic chloroplasts occur in

Options

A. Pea
B. Mango
C. Sugarcane
D. Cotton.

Answer

**Step-by-Step Solution:**

1. **Understand the Concept of Dimorphic Chloroplasts:**
- Dimorphic chloroplasts refer to the presence of two different types of chloroplasts within a plant. These types are distinguished by their structure and function.

2. **Identify the Types of Chloroplasts:**
- In dimorphic chloroplasts, one type contains grana (stacks of thylakoids) and the other type does not contain grana. The chloroplasts without grana are typically found surrounding vascular bundles.

3. **Link Dimorphic Chloroplasts to Plant Types:**
- Dimorphic chloroplasts are primarily found in C4 plants. C4 plants have a unique mechanism for photosynthesis that allows them to efficiently fix carbon dioxide in hot and dry environments.

4. **Evaluate the Given Options:**
- The options provided are:
- Pea (C3 plant)
- Mango (C3 plant)
- Sugarcane (C4 plant)
- Cotton (C3 plant)
- Among these, only sugarcane is classified as a C4 plant.

5. **Conclusion:**
- Since dimorphic chloroplasts are characteristic of C4 plants and sugarcane is the only C4 plant listed, the answer is that dimorphic chloroplasts occur in sugarcane.

**Final Answer: Dimorphic chloroplasts occur in sugarcane.**
