Some features of cells are listed. Which features can be found both in plant cells and prokaryotic cells?
I. Cell wall
II. Cell surface membrane
III. Ribosome

Options

A. I and III only
B. II and III only
C. I and III only
D. I, II and III

Answer

To solve the question regarding which features can be found both in plant cells and prokaryotic cells, we will analyze each of the listed features one by one.

### Step-by-Step Solution:

1. **Identify the Features:**
- The features listed are:
I. Cell wall
II. Cell surface membrane
III. Ribosome

2. **Analyze Feature I: Cell Wall**
- Plant cells have a rigid cell wall made of cellulose.
- Prokaryotic cells (such as bacteria) also have a cell wall, which is typically made of peptidoglycan.
- **Conclusion:** The cell wall is present in both plant cells and prokaryotic cells.

3. **Analyze Feature II: Cell Surface Membrane**
- Both plant cells and prokaryotic cells have a cell surface membrane (also known as the plasma membrane).
- The cell surface membrane functions to protect the cell and regulate what enters and exits.
- **Conclusion:** The cell surface membrane is present in both plant cells and prokaryotic cells.

4. **Analyze Feature III: Ribosome**
- Ribosomes are the sites of protein synthesis.
- They are present in all living cells, including both eukaryotic cells (like plant cells) and prokaryotic cells.
- Eukaryotic ribosomes are larger (80S) compared to prokaryotic ribosomes (70S), but both types perform the same function.
- **Conclusion:** Ribosomes are present in both plant cells and prokaryotic cells.

5. **Final Conclusion:**
- All three features (cell wall, cell surface membrane, and ribosome) are found in both plant cells and prokaryotic cells.
- Therefore, the correct answer is **I, II, and III**.
