Differentiate between:
Water potential and Diffusion pressure deficit.

Explanation

To differentiate between Water Potential and Diffusion Pressure Deficit (DPD), we can create a structured comparison highlighting their key characteristics:

### Step-by-Step Solution

1. **Definition**:
- **Diffusion Pressure Deficit (DPD)**: DPD is defined as the difference between the diffusion pressure of a solution and that of pure solvent (water).
- **Water Potential**: Water potential is defined as the difference between the free energy of water molecules in pure water and in a solution.
