Bacteria have cell membrane made of

Options

A. Chitin
B. Cellulose
C. Proteins and phospholipds
D. Fats.

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks about the composition of the cell membrane in bacteria.

2. **Understand Bacteria**: Bacteria are classified as prokaryotes, which are organisms that lack a true nucleus and membrane-bound organelles.

3. **Cell Structure of Bacteria**: Bacteria have an outer cell wall and an inner cell membrane (also known as the plasma membrane). The cell wall is primarily made up of peptidoglycan.

4. **Composition of Cell Membrane**: The cell membrane in bacteria is similar to that in eukaryotic cells. It is composed of a lipid bilayer primarily made up of phospholipids, along with proteins that can be either intrinsic (embedded) or extrinsic (attached to the surface).

5. **Evaluate the Options**:
- **Chitin**: Incorrect. Chitin is a component of the cell wall in fungi, not in bacteria.
- **Cellulose**: Incorrect. Cellulose is found in the cell wall of plants, not in bacteria.
- **Proteins**: Partially correct, but not the complete answer since it does not mention the lipid component.
- **Phospholipid fats**: Correct. The cell membrane is primarily made of phospholipids and proteins.

6. **Conclusion**: The correct answer is that the cell membrane of bacteria is made up of phospholipids and proteins.

**Final Answer**: The cell membrane of bacteria is made up of phospholipid fats and proteins.
