Desmosome is the modification of

Options

A. Golgi bodies
B. plasma membrane
C. ER-nucleus complex
D. endoplasmic membrane

Answer

**Step-by-Step Solution:**

1. **Understanding Desmosomes**: Desmosomes are specialized structures found in cells that play a crucial role in cell adhesion. They are important for maintaining the structural integrity of tissues.

2. **Identifying the Origin**: Desmosomes are specifically modifications of the plasma membrane. This means that they arise from the cell membrane and are not separate entities.

3. **Function of Desmosomes**: The primary function of desmosomes is to provide strong adhesion between adjacent cells. This is essential in tissues that experience significant mechanical stress, such as epithelial tissues.

4. **Intercellular Junctions**: Desmosomes are classified as intercellular junctions. They connect the cytoskeletons of neighboring cells, contributing to the overall mechanical strength of the tissue.

5. **Analyzing the Options**:
- **Golgi Bodies**: Incorrect, as they are involved in processing and packaging proteins.
- **Plasma Membrane**: Correct, as desmosomes are modifications of this membrane.
- **ER Nucleus Complex**: Incorrect, as this refers to the endoplasmic reticulum and nucleus, not a modification.
- **Endoplasmic Membrane**: Incorrect, as this term does not refer to a specific structure related to desmosomes.

6. **Conclusion**: Therefore, the correct answer is that desmosomes are modifications of the plasma membrane.

**Final Answer**: Desmosome is a modification of the plasma membrane.
