The movement of water is along

Options

A. 1.Turgor gradient
B. 2.DPD gradient
C. 3.Diffusion gardient
D. 4.Osmotic gradient

Answer

**Step-by-Step Solution:**

1. **Understanding Water Movement in Plants:**
Water movement in plants is essential for various physiological processes, including nutrient transport, photosynthesis, and maintaining turgor pressure.

2. **Identifying the Options:**
The question provides four options regarding the movement of water:
- A) Turbulent gradient
- B) DPD gradient
- C) Diffusion gradient
- D) Osmotic gradient

3. **Defining DPD:**
DPD stands for Diffusion Pressure Deficit. It refers to the difference in water potential between the inside of a plant cell and the surrounding solution.

4. **Explaining the Concept of DPD Gradient:**
When a plant cell is placed in a hypotonic solution (where the external solution has a lower solute concentration than the cell), water moves into the cell due to the DPD gradient. This movement occurs because the water potential inside the cell is higher than that in the external solution.

5. **Understanding Water Movement:**
The movement of water from an area of higher water potential to an area of lower water potential results in the process known as exosmosis when water moves out of the cell.

6. **Conclusion:**
Based on the explanation, the correct answer to the question is the DPD gradient, as it is the driving force for water movement in this context.

**Final Answer: DPD Gradient (Diffusion Pressure Deficit)**
