Adjacent epithelial cells are joined by :

Options

A. oxysomes
B. desmonemes
C. desmosomes
D. plasmodesmata

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how adjacent epithelial cells are joined together. This indicates we need to identify the specific structures or junctions that facilitate this connection.

2. **Analyzing the Options**:
- **Option 1: Oxisomes**: These are small round bodies found in the mitochondria, specifically in the inner membrane's folds (cristae). They are involved in ATP synthesis but do not play a role in joining epithelial cells.
- **Option 2: Desmonymae**: This term refers to nematocysts, which are specialized cells found in certain organisms like jellyfish. They have long, stinging structures but are not related to cell junctions in epithelial tissues.
- **Option 3: Desmosomes**: Desmosomes are specialized structures that connect adjacent epithelial cells, providing mechanical strength and stability to the tissue. This is the correct answer.
- **Option 4: Plasmodesmata**: These are channels that allow communication between plant cells and are not found in animal cells. Therefore, they do not join adjacent epithelial cells.

3. **Conclusion**: After analyzing all options, the correct answer is **Desmosomes**, as they are specifically responsible for joining adjacent epithelial cells.

**Final Answer**: Adjacent epithelial cells are joined by **Desmosomes**.
