Define gravity potential. When it is ignored?

Explanation

### Step-by-Step Text Solution:

1. **Definition of Gravity Potential**:
- Gravity potential refers to the potential energy per unit volume of water due to the gravitational force acting on it. It is a component of water potential in plants and is influenced by the height of the water column above a reference point, the density of the water, and the acceleration due to gravity.

2. **Components of Gravity Potential**:
- **Height of Water**: The height of the water column above a reference point affects the gravity potential. The higher the water column, the greater the gravitational potential energy.
- **Density of Water**: The density of water also plays a role in determining the gravity potential. Denser water will have a higher potential energy at a given height.
