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 determine which features can be found both in plant cells and prokaryotic cells, we will analyze each feature listed in the question:

1. **Cell Wall**:
- Plant cells have a rigid cell wall made of cellulose, which provides structure and support.
- Prokaryotic cells (such as bacteria) also have a cell wall, which is typically made of peptidoglycan.
- Therefore, the cell wall is a feature found in both plant cells and prokaryotic cells.

2. **Cell Surface Membrane**:
- Both plant cells and prokaryotic cells possess a cell surface membrane (also known as the plasma membrane).
- This membrane is crucial for regulating the movement of substances in and out of the cell.
- Hence, the cell surface membrane is also a feature found in both types of cells.

3. **Ribosomes**:
- Ribosomes are the cellular structures responsible for protein synthesis.
- Both plant cells and prokaryotic cells contain ribosomes, although the size and structure may differ slightly (prokaryotic ribosomes are smaller).
- Thus, ribosomes are another feature present in both plant and prokaryotic cells.

Now, summarizing the findings:
- **Cell Wall**: Present in both plant and prokaryotic cells.
- **Cell Surface Membrane**: Present in both plant and prokaryotic cells.
- **Ribosomes**: Present in both plant and prokaryotic cells.

Since all three features (I, II, and III) are found in both plant cells and prokaryotic cells, the correct answer is that all of these features can be found in both types of cells.

### Final Answer:
All three features (I, II, and III) can be found in both plant cells and prokaryotic cells.
