Desmosomes possess

Options

A. desmotubules
B. intercellular cementing material
C. myofibrils
D. all of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Desmosomes**: Desmosomes are specialized structures in cells that facilitate cell-to-cell adhesion. They are also referred to as "macula adherens."

2. **Function of Desmosomes**: The primary role of desmosomes is to connect adjacent cells, forming a junction complex that helps maintain the integrity of tissues.

3. **Location of Desmosomes**: Desmosomes are typically located on the lateral sides of the plasma membrane of cells, arranged in a somewhat random manner.

4. **Analyzing the Options**:
- **Desmotubules**: These are structures found in plasmodesmata, which are channels in plant cells that allow for the exchange of materials between adjacent cells. They are not a component of desmosomes.
- **Intercellular Cementing Material**: This is the correct answer. It refers to the material that provides adhesion between cells, which is a key function of desmosomes.
- **Myofibrils**: These are rod-like structures found in muscle cells and are not related to cell-to-cell adhesion in the context of desmosomes.

5. **Conclusion**: The correct answer is that desmosomes possess intercellular cementing material, as it is essential for their function in cell adhesion.

**Final Answer**: Desmosomes possess intercellular cementing material.
