________ are found in both prokaryotic and eukaryotic cells as they produce proteins

Options

A. Mitochondria
B. Ribosomes
C. Golgi Body
D. Plastids

Answer

**Step-by-Step Solution:**

1. **Understanding Cell Types**: Begin by recognizing the two main types of cells: prokaryotic and eukaryotic. Prokaryotic cells are simpler and do not have membrane-bound organelles, while eukaryotic cells are more complex and contain these organelles.

2. **Identifying Organelles**: The question lists several organelles: mitochondria, ribosomes, Golgi body, and plastids. We need to determine which of these are found in both prokaryotic and eukaryotic cells.

3. **Analyzing Each Organelle**:
- **Mitochondria**: Known as the powerhouse of the cell, mitochondria are involved in energy production. They are found only in eukaryotic cells, not in prokaryotic cells.
- **Ribosomes**: These are the protein factories of the cell and are responsible for protein synthesis. Ribosomes are present in both prokaryotic and eukaryotic cells.
- **Golgi Body**: This organelle is involved in modifying, sorting, and packaging proteins. It is found only in eukaryotic cells.
- **Plastids**: These are involved in photosynthesis and storage of products. Plastids are also found only in eukaryotic cells.

4. **Conclusion**: After analyzing the organelles, we find that ribosomes are the only organelles that are present in both prokaryotic and eukaryotic cells.

5. **Final Answer**: Therefore, the answer to the question is **ribosomes**.
