Site of protein synthesis in a prokaryotic cell is

Options

A. Cytosol
B. Plasma membrane
C. Ribosomes
D. Gas vacuoles

Answer

To determine the site of protein synthesis in a prokaryotic cell, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Prokaryotic Cells**:
- Prokaryotic cells are simple, unicellular organisms that lack a nucleus and membrane-bound organelles.

2. **Identify Organelles**:
- Since prokaryotes do not have membrane-bound organelles, we need to identify what structures are present that facilitate protein synthesis.

3. **Focus on Ribosomes**:
- Ribosomes are the key structures responsible for protein synthesis. They are not membrane-bound and can be found in prokaryotic cells.

4. **Location of Ribosomes**:
- In prokaryotic cells, ribosomes are found freely floating in the cytoplasm. This is where the translation of mRNA into proteins occurs.

5. **Conclusion**:
- Therefore, the site of protein synthesis in a prokaryotic cell is the cytoplasm, where ribosomes are located.

### Final Answer:
The site of protein synthesis in a prokaryotic cell is the **cytoplasm**.
