What is symplast pathway?

Explanation

### Step-by-Step Solution:

1. **Definition of Symplast Pathway**: The symplast pathway refers to the movement of water and dissolved substances through the cytoplasm of adjacent plant cells. This pathway is interconnected via plasmodesmata, which are microscopic channels that connect the cytoplasm of neighboring cells.

2. **Comparison with Apoplast Pathway**: Unlike the apoplast pathway, which involves the movement of substances through the cell walls and intercellular spaces, the symplast pathway specifically involves the cytoplasm of the cells. This means that the symplast pathway does not involve any movement through the cell wall.

3. **Process of Water Movement**: Water absorption begins at the root hairs, which are specialized structures that increase the surface area for absorption. From the root hairs, water moves into the epidermis, then through the cortex, and reaches the endodermis.
