The pathway for water that lies with the cell walls is

Options

A. the apoplastic pathway
B. the symplastic pathway
C. the casparian pathway
D. the endodermal pathway

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the pathway through which water moves that is associated with the cell walls of plant cells.

2. **Identifying the Pathways**: There are two primary pathways for water movement in plants: the epoplastic pathway and the symplastic pathway.

3. **Defining the Epoplastic Pathway**: The epoplastic pathway involves the movement of water through the cell walls and intercellular spaces. This pathway primarily utilizes the dead components of the plant, such as the cell walls.

4. **Defining the Symplastic Pathway**: In contrast, the symplastic pathway involves the movement of water through the cytoplasm of plant cells via plasmodesmata, which are the channels that connect the cytoplasm of adjacent living cells. This pathway does not involve the cell walls.

5. **Analyzing Other Options**:
- The "Caspian pathway" is not a recognized pathway for water movement in plants.
- The "anodermal pathway" is also not a standard term used in plant physiology.

6. **Conclusion**: Since the question specifically asks for the pathway that lies with the cell walls, the correct answer is the **epoplastic pathway**.

**Final Answer**: The pathway for water that lies with the cell walls is the **epoplastic pathway**.
