Chromoplasm refers to

Options

A. Cytoplasm rich in chloroplasts
B. Cytoplasm having photosynthetic pigments
C. Peripheral thylakoid rich part of cyanobacteria
D. Inner thylakoid rich part of cyanobacterial cell.

Answer

**Step-by-Step Solution:**

1. **Understanding Chromoplasm**:
- Chromoplasm is a term associated with cyanobacteria, also known as blue-green algae. It is important to recognize that this term refers to a specific part of the cell structure in these organisms.

2. **Characteristics of Chromoplasm**:
- Chromoplasm is characterized by being rich in nucleic acids and contains a homogeneous mixture of chromosomes. This indicates that it plays a role in the genetic material of the cyanobacteria.

3. **Presence of Thylakoids**:
- While chromoplasm does contain thylakoids, it is crucial to note that it does not contain photosynthetic pigments. This sets it apart from other cellular components that might be involved in photosynthesis.

4. **Evaluating the Options**:
- **Option A**: "Cytoplasm rich in chloroplast" - This is incorrect because cyanobacteria do not have chloroplasts; they have thylakoids instead.
- **Option B**: "Cytoplasm having photosynthetic pigments" - This is also incorrect since chromoplasm lacks photosynthetic pigments.
- **Option C**: "Peripheral thylakoid rich part of cyanobacteria" - This is correct as chromoplasm is associated with thylakoids.
- **Option D**: "Inner thylakoid part of cyanobacterial cell" - This is incorrect because it does not accurately describe chromoplasm.

5. **Conclusion**:
- Based on the evaluation of the options, the correct answer is **C**: "Peripheral thylakoid rich part of cyanobacteria".
