State the relationship between water potential and solute potential for a solution at atmospheric pressure .

Explanation

To answer the question regarding the relationship between water potential and solute potential for a solution at atmospheric pressure, we can follow these steps:

### Step-by-Step Solution:

1. **Define Water Potential (Ψ)**: Water potential is a measure of the potential energy in water and is used to predict the direction of water movement. It is affected by solute concentration and pressure.

2. **Components of Water Potential**: Water potential (Ψ) is composed of two main components:
- **Solute Potential (Ψs)**: This is the potential of water to move due to the presence of solutes. It is always negative or zero (in pure water).
