List the different factors which affect water potential.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Water Potential**: Water potential is defined as the potential energy of water in a system, which influences the movement of water. It is a measure of the tendency of water to move from one area to another and is expressed in terms of pressure.

2. **Components of Water Potential**: Water potential consists of two main components:
- **Solute Potential (Ψs)**: This is the effect of solute concentration on the overall water potential. Water moves from areas of low solute concentration (high water potential) to areas of high solute concentration (low water potential).
- **Pressure Potential (Ψp)**: This is the physical pressure exerted on the water in a system. It can be positive (turgor pressure in plant cells) or negative (tension in xylem).
