The movement of water through the root layers is ultimately symplastic in the endodermis. Give a reason.

Explanation

### Step-by-Step Solution:

1. **Understanding Water Absorption**: Water absorption in plants primarily occurs through root hairs, which are small extensions at the tips of roots. These root hairs increase the surface area for water uptake.

2. **Pathways of Water Movement**: After water is absorbed by the root hairs, it can move deeper into the root layers through two main pathways: the apoplast pathway and the symplast pathway.

3. **Apoplast Pathway**: The apoplast pathway involves the movement of water through the cell walls of adjacent cells. This pathway allows water to move freely through the continuous system of cell walls without entering the cells.
