The correct Answer is:
To answer the question about the membranous cell organelles inside chloroplasts, we will analyze each option provided. ### Step-by-Step Solution: 1. **Understanding Chloroplast Structure**: - Chloroplasts are organelles found in plant cells and are responsible for photosynthesis. They contain various structures, including thylakoids, stroma, and pigments. 2. **Evaluating the Options**: - **Option 1: Pigment**: - Chloroplasts contain pigments like chlorophyll and carotenoids, which are essential for capturing light energy during photosynthesis. However, pigments themselves are not considered membranous organelles. - **Conclusion**: This option is incorrect. - **Option 2: Circular DNA**: - Chloroplasts do have their own DNA, which is circular. However, DNA is not classified as a membranous organelle. It is a genetic material found within the chloroplast. - **Conclusion**: This option is incorrect. - **Option 3: Granum**: - Granum refers to a stack of thylakoids, which are membrane-bound structures within the chloroplast. While granum is associated with membranes, it is not a standalone membranous organelle but rather a part of the thylakoid system. - **Conclusion**: This option is incorrect. - **Option 4: Ribosome**: - Ribosomes are indeed present in chloroplasts and are responsible for protein synthesis. They are considered membranous organelles because they are associated with the endoplasmic reticulum in eukaryotic cells and can exist freely in the stroma of chloroplasts. - **Conclusion**: This option is correct. 3. **Final Answer**: - The membranous cell organelle inside chloroplasts is **Ribosome** (Option 4).
