The loose sheath of glycocalyx is called

Options

A. Slime layer
B. Capsule
C. Cell wall
D. Plasma membrane

Answer

**Step-by-Step Solution:**

1. **Understanding Glycocalyx**: The glycocalyx is a layer found outside the cell wall of some bacteria. It is composed of polysaccharides and glycoproteins and serves various functions, including protection and adherence.

2. **Identifying the Loose Sheath**: The question specifically asks for the loose sheath of glycocalyx. This indicates that we are looking for a term that describes an unorganized or loosely structured layer.

3. **Evaluating the Options**:
- **Option 1: Slime Layer**: This is an unorganized layer of extracellular material that surrounds the bacterial cell. It is indeed the loose sheath of glycocalyx. Therefore, this option is correct.
- **Option 2: Capsule**: This is a thicker and more organized layer of glycocalyx. It provides more protection and is not considered loose. Thus, this option is incorrect.
- **Option 3: Cell Wall**: The cell wall is a rigid structure composed of peptidoglycan in bacteria. It is not a part of the glycocalyx and is not loose. Hence, this option is incorrect.
- **Option 4: Plasma Membrane**: The plasma membrane is a selectively permeable barrier that surrounds the cell. It is not related to the glycocalyx and is not a loose sheath. Therefore, this option is also incorrect.

4. **Conclusion**: Based on the evaluation of the options, the correct answer is **Slime Layer**.

**Final Answer**: The loose sheath of glycocalyx is called the **Slime Layer**.
