Which of the the following components provides sticky character to the wall bacterial cell ?

Options

A. Cell wall
B. Nuclear membrane
C. Plasma membrane
D. Glycocalyx

Answer

To determine which component provides a sticky character to the wall of a bacterial cell, we can analyze the options given based on our understanding of bacterial cell structure.

### Step-by-Step Solution:

1. **Understanding Bacterial Structure**:
- Bacteria are prokaryotic organisms, meaning they lack a true nucleus and nuclear membrane. They are classified under the Kingdom Monera.

2. **Identifying Cell Components**:
- Bacteria have several key components: a cell wall, plasma membrane, and sometimes additional structures like a glycocalyx.

3. **Analyzing the Cell Wall**:
- The bacterial cell wall is primarily made of peptidoglycan, which is a rigid structure. Although it provides protection and shape to the bacteria, it does not contribute to stickiness.

4. **Examining the Plasma Membrane**:
- The plasma membrane is the innermost layer and is responsible for selective permeability, allowing certain substances to enter and exit the cell. It does not have a sticky character.

5. **Considering Glycocalyx**:
- Glycocalyx is an outer layer composed of carbohydrates. The term "glyco" refers to carbohydrates, and "calyx" means outgrowth. This layer is known for its slimy texture, which provides a sticky character to the bacterial cell.

6. **Conclusion**:
- Based on the analysis, the component that provides the sticky character to the wall of a bacterial cell is the **glycocalyx**.

### Final Answer:
The correct answer is **4. Glycocalyx**.
