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

Options

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

Answer

To answer the question "Which of the following components provides sticky character to the bacterial cell?" we will analyze each of the options provided.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) Cell wall
- B) Nuclear membrane
- C) Plasma membrane
- D) Glycocalyx

2. **Analyze the Cell Wall**:
- The cell wall is a rigid structure that provides strength and rigidity to the bacterial cell. It is primarily made up of peptidoglycan. While it is essential for maintaining the shape and integrity of the cell, it does not contribute to stickiness.
- **Conclusion**: The cell wall does not provide a sticky character.

3. **Analyze the Nuclear Membrane**:
- The nuclear membrane is a characteristic feature of eukaryotic cells and is absent in prokaryotic cells like bacteria. Therefore, this option cannot provide any sticky character to bacterial cells.
- **Conclusion**: The nuclear membrane is not present in bacterial cells.

4. **Analyze the Plasma Membrane**:
- The plasma membrane in bacteria is composed of a lipid bilayer and is semi-permeable. Its primary function is to regulate the exchange of substances in and out of the cell. However, it does not have a sticky character.
- **Conclusion**: The plasma membrane does not provide stickiness.

5. **Analyze the Glycocalyx**:
- The glycocalyx is an outer layer found beyond the cell wall in some bacteria. It is composed of glycolipids and glycoproteins, forming a slimy, gelatinous covering. This structure provides a sticky character to the bacterial cell, helping it adhere to surfaces and protect against desiccation and nutrient loss.
- **Conclusion**: The glycocalyx provides the sticky character to the bacterial cell.

6. **Final Answer**: Based on the analysis, the correct answer is **D) Glycocalyx**.
