The cytoplasm of adjacent plant cells is connected to each other by :

Options

A. Plasmalemma
B. Desmosome
C. Plasmodesmata
D. Plasmotubule

Answer

To answer the question, "The cytoplasm of adjacent plant cells is connected to each other by:", we need to analyze the options provided and determine which one correctly identifies the structure responsible for connecting the cytoplasm of adjacent plant cells.

### Step-by-Step Solution:

1. **Understanding the Question**:
- We are asked about the connection between the cytoplasm of adjacent plant cells.

2. **Evaluating Option 1: Plasma Membrane (Plasma Lemma)**:
- The plasma membrane surrounds each cell and provides protection and regulates the movement of substances in and out of the cell.
- However, it does not connect the cytoplasm of adjacent cells directly.
- **Conclusion**: This option is incorrect.

3. **Evaluating Option 2: Desmosomes**:
- Desmosomes are structures that provide adhesion between cells, linking their cytoskeletons to provide mechanical strength.
- They do not form direct connections between the cytoplasm of adjacent plant cells.
- **Conclusion**: This option is also incorrect.

4. **Evaluating Option 3: Plasmodesmata**:
- Plasmodesmata are microscopic channels that penetrate the cell walls of adjacent plant cells.
- They allow for the direct connection of the cytoplasm between these cells, facilitating communication and transport of substances.
- **Conclusion**: This option is correct.

5. **Evaluating Option 4: Plasmotubule**:
- Plasmotubules are involved in connecting neighboring pollen tubes, not plant cells in general.
- They do not serve the purpose of connecting the cytoplasm of adjacent plant cells.
- **Conclusion**: This option is incorrect.

### Final Answer:
The cytoplasm of adjacent plant cells is connected to each other by **Plasmodesmata**.
