Movement of `H_(2)O` through cell wall is called

Options

A. Symplast
B. Apoplast
C. Tonoplast
D. All of these

Answer

To answer the question regarding the movement of water (H₂O) through the cell wall, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding the Options:**
- The question provides four options: synplast, apoplast, tonoplast, and all of these. We need to identify which term specifically refers to the movement of water through the cell wall.

2. **Defining Apoplast:**
- Apoplast refers to the pathway outside the plasma membrane, which includes the cell walls and intercellular spaces. In this space, water and solutes can move freely without crossing any cell membranes.

3. **Defining Synplast:**
- Synplast is the term used for the region inside the plasma membrane where water and low molecular weight solutes can diffuse. This is not the pathway through the cell wall.

4. **Defining Tonoplast:**
- Tonoplast is the membrane surrounding the vacuole in plant cells. It is not related to the movement of water through the cell wall.

5. **Identifying the Correct Answer:**
- Since the question specifically asks about the movement of water through the cell wall, the correct answer is **apoplast**. This is because apoplastic transport involves the movement of water and solutes through the cell walls and intercellular spaces.

6. **Conclusion:**
- Therefore, the movement of H₂O through the cell wall is called **apoplast**.

### Final Answer:
The movement of H₂O through the cell wall is called **apoplast**.
