Name the intercellular connections between adjacent plant cells. What is their function ?

Answer

### Step-by-Step Solution:

1. **Identify the Intercellular Connections**:
The intercellular connections between adjacent plant cells are called **Plasmodesmata**.

2. **Describe the Structure**:
Plasmodesmata are **coaxial membranous channels** that penetrate the cell walls of adjacent plant cells.

3. **Explain the Function**:
The primary function of plasmodesmata is to **link the cytoplasm** of adjacent cells. They connect not only the cytoplasm but also the **plasma membrane** and the **endoplasmic reticulum** of the neighboring cells.

4. **Detail the Communication Aspect**:
Through plasmodesmata, there is a **direct cytoplasmic linkage** which facilitates **cell-to-cell communication**.

5. **Mention the Exchange of Materials**:
Plasmodesmata allow for the exchange of **small molecules and macromolecules** between adjacent plant cells, which is crucial for maintaining cellular functions and homeostasis.

6. **Summarize the Importance**:
In summary, plasmodesmata are essential for **communication and material exchange** between adjacent plant cells, ensuring that they can work together effectively.
