The greater the concentration of water in system the greater is its (A)_____ or (B)_____

Answer

To solve the question, "The greater the concentration of water in the system the greater is its (A)_____ or (B)_____," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Water Concentration**:
- The question refers to the concentration of water in a system. In biological terms, this often relates to how water behaves in plant cells and their surrounding environment.

2. **Defining Key Terms**:
- **Water Potential**: This is a measure of the potential energy of water in a system and is denoted as Ψw (psi w). It indicates the tendency of water to move from one area to another.
- **Kinetic Energy**: Water molecules are in constant motion, and this motion is associated with kinetic energy. The more water molecules present, the greater the kinetic energy due to increased movement.

3. **Analyzing the Relationship**:
- When the concentration of water increases, the water potential also increases. This is because pure water has a water potential of zero, and as solutes are added, the water potential becomes more negative. Therefore, a higher concentration of water correlates with a higher water potential.
- Similarly, with more water molecules present, the kinetic energy of these molecules also increases due to their motion.

4. **Filling in the Blanks**:
- Based on the definitions and relationships discussed, we can fill in the blanks:
- (A) Kinetic Energy
- (B) Water Potential

Thus, the completed statement is: "The greater the concentration of water in the system, the greater is its (A) Kinetic Energy or (B) Water Potential."
