A membranous cell organelles which are found in both prokaryotic, eukaryotic cells are

Options

A. Mitochondria
B. Ribosomes
C. Microbodies
D. Vacuole

Answer

### Step-by-Step Solution

1. **Understanding the Question**: The question asks for a membranous cell organelle that is found in both prokaryotic and eukaryotic cells.

2. **Identifying Cell Types**:
- **Prokaryotic Cells**: These cells do not have membrane-bound organelles. Examples include bacteria and archaea.
- **Eukaryotic Cells**: These cells do have membrane-bound organelles. Examples include plant and animal cells.

3. **Analyzing the Options**:
- **Mitochondria**: This organelle is membrane-bound and is found only in eukaryotic cells, not in prokaryotic cells.
- **Ribosomes**: These are not membrane-bound organelles; they are found in both prokaryotic and eukaryotic cells, but they do not fit the criteria of being membranous.
- **Microbodies**: These are also membrane-bound organelles found in eukaryotic cells but are not present in prokaryotic cells.
- **Cell Wall**: This is not an organelle but a structure found in many prokaryotic and some eukaryotic cells (like plants).

4. **Conclusion**: After analyzing the options, it becomes clear that none of the options provided are correct because ribosomes, while found in both cell types, are not membranous. However, if we strictly consider the question, ribosomes are the only organelles present in both cell types, even though they are not membranous.

5. **Final Answer**: The correct answer to the question is **Ribosomes**.
