Amembranous cell organelles inside chloroplast are

Options

A. pigments
B. circular DNA
C. Granum
D. Ribosomes

Answer

To answer the question about the membranous cell organelles inside chloroplasts, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chloroplasts**:
- Chloroplasts are organelles found in plant cells and some protists. They are responsible for photosynthesis, converting light energy into chemical energy.

2. **Identifying Membranous Organelles**:
- Membranous organelles are structures within the cell that are surrounded by membranes. In chloroplasts, these include thylakoids, stroma, and others.

3. **Evaluating the Options**:
- The question provides several options regarding what membranous organelles are present in chloroplasts.

4. **Analyzing Each Option**:
- **Option 1: Pigments**: This is incorrect. While chlorophyll (a pigment) is present in chloroplasts, it is not a membranous organelle.
- **Option 2: Circular DNA**: This is also incorrect. Chloroplasts have their own DNA, but DNA itself is not a membranous organelle.
- **Option 3: Granum**: This option is misleading. Granum refers to stacks of thylakoids, which are indeed membranous structures, but the term "granum" itself does not refer to a standalone organelle.
- **Option 4: Ribosomes**: This is the correct answer. Ribosomes are present in chloroplasts and are involved in protein synthesis. They are not surrounded by membranes but are associated with the thylakoid membranes.

5. **Conclusion**:
- The correct answer to the question is **Ribosomes** as they are the membranous cell organelles associated with chloroplasts.

### Final Answer:
The membranous cell organelles inside chloroplasts are **Ribosomes**.
