Plasmodesmata connections help in

Options

A. cytoplasmic streaming
B. synchronous mitotic divisions
C. locomotion of unicellular organisms
D. movement of substances between cells

Answer

**Step-by-Step Solution:**

1. **Understanding Plasmodesmata:**
- Plasmodesmata are microscopic channels that traverse the cell walls of plant cells and enable communication and transport between adjacent cells. They are essential for the exchange of substances, such as nutrients, ions, and signaling molecules.

2. **Function of Plasmodesmata:**
- The primary function of plasmodesmata is to facilitate the movement of substances between neighboring plant cells. This is crucial for maintaining cellular homeostasis and coordinating responses to environmental changes.

3. **Analyzing the Options:**
- Option 1: Cytoplasmic streaming - This refers to the movement of the cytoplasm within a cell and does not involve intercellular connections. Therefore, this option is incorrect.
- Option 2: Synchronous mitotic division - This describes the process of cell division and does not directly relate to the function of plasmodesmata. Hence, this option is also incorrect.
- Option 3: Locomotion of unicellular organisms - This pertains to the movement of single-celled organisms, which typically use structures like flagella or cilia. This option is not relevant to plasmodesmata, making it incorrect.
- Option 4: Movement of substances between cells - This accurately describes the primary role of plasmodesmata, making it the correct answer.

4. **Conclusion:**
- Based on the analysis of the options, the correct answer is that plasmodesmata connections help in the movement of substances between cells.

**Final Answer:**
Plasmodesmata connections help in the movement of substances between cells.
