Which of the pathways of water movement involves cell wall and intercellular spaces?

Options

A. Vacuolar pathway
B. Protoplast pathway
C. Symplast pathway
D. Apoplast pathway

Answer

**Step-by-Step Solution:**

1. **Understanding Water Movement in Plants:**
- Water movement in plants occurs through different pathways. The two main pathways are the apoplast pathway and the symplast pathway.

2. **Defining the Apoplast Pathway:**
- The apoplast pathway involves the movement of water through the cell walls and intercellular spaces. It is a continuous system of adjacent cell walls that allows water to flow freely without entering the cell's cytoplasm.

3. **Defining the Symplast Pathway:**
- In contrast, the symplast pathway involves the movement of water through the cytoplasm of cells. This pathway is made up of interconnected protoplasts (the living part of the cell).

4. **Identifying the Correct Pathway:**
- Since the question asks for the pathway that involves cell walls and intercellular spaces, we focus on the apoplast pathway. This pathway allows water to move through the spaces between cells and along the cell walls.

5. **Conclusion:**
- Therefore, the pathway of water movement that involves cell walls and intercellular spaces is the **apoplast pathway**.

**Final Answer: Apoplast Pathway**
