The cytoplasm of neighbouring cells is connected with the help of:

Options

A. Middle lamella
B. Primary wall
C. Mitochondria
D. Plasmodesmata

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how the cytoplasm of neighboring cells is connected. This is a fundamental concept in cell biology, particularly in plant cells.

2. **Analyzing the Options**:
- **Option 1: Middle Lamella**: This is a layer that cements two adjoining plant cells together, but it does not directly connect their cytoplasm.
- **Option 2: Primary Wall**: This is the outermost layer of the plant cell wall, which provides structure but does not connect the cytoplasm of neighboring cells.
- **Option 3: Mitochondria**: These organelles are involved in energy production through cellular respiration, but they do not play a role in connecting the cytoplasm of cells.
- **Option 4: Plasmodesmata**: These are microscopic channels that directly connect the cytoplasm of adjacent plant cells, allowing for transport and communication between them.

3. **Identifying the Correct Answer**: Based on the analysis, the correct answer is **Plasmodesmata** (Option 4), as they are specifically designed to connect the cytoplasm of neighboring plant cells.

4. **Conclusion**: The cytoplasm of neighboring cells is connected with the help of plasmodesmata, which facilitate communication and transport between cells.
