What are plasmodesmata and what is their role?

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Plasmodesmata**: Plasmodesmata are specialized structures that act as cytoplasmic bridges between adjacent plant cells. They facilitate communication and transport between cells.

2. **Location**: These structures are found in the cell walls of plant cells, specifically between the adjacent cell walls. They develop through minor pores in the cell walls.

3. **Formation of Protoplasmic Continuum**: Plasmodesmata create a continuous network of cytoplasm between plant cells, known as the symplast. This allows for the movement of substances across cells.
