In prokaryotes the Glycocalyx when it is thick is called

Options

A. Mesosome
B. Cell wall
C. Slime layer
D. Capsule

Answer

**Step-by-Step Solution:**

1. **Understanding Glycocalyx**: In prokaryotic cells, the glycocalyx is an outer layer that surrounds the cell wall. It is composed of polysaccharides and proteins.

2. **Forms of Glycocalyx**: The glycocalyx can exist in two forms: a loose, slimy layer and a thicker, more organized layer.

3. **Identifying the Thick Layer**: When the glycocalyx is thick and well-organized, it is referred to as a "capsule." This is distinct from the loose form, which is often called a "slime layer."

4. **Conclusion**: Therefore, in prokaryotes, when the glycocalyx is thick, it is specifically called a "capsule."

5. **Final Answer**: The correct answer to the question is "capsule."
