Minimum solute potential means

Options

A. More negative solute potential
B. Minimum solute concentration
C. Maximum turgidty
D. Both B and C.

Answer

To answer the question "Minimum solute potential means," we need to understand the concepts of solute potential and how it relates to water movement in plant cells. Here’s a step-by-step breakdown of the solution:

### Step 1: Define Solute Potential
- Solute potential, also known as osmotic potential, refers to the potential of a solution to draw water across a semi-permeable membrane. It is influenced by the concentration of solutes in the solution.

### Step 2: Understand Minimum Solute Potential
- Minimum solute potential indicates the lowest possible value of solute potential. This typically occurs when the concentration of solutes is at its minimum.

### Step 3: Relate Solute Potential to Water Movement
- A solution with minimum solute potential has a lower ability to draw in water. This means that if the solute concentration is low, the tendency for water to move into the cells is also reduced.

### Step 4: Identify the Implications of Minimum Solute Potential
- Minimum solute potential corresponds to two key concepts:
1. **Minimum Solute Concentration**: As solute potential decreases, the concentration of solutes in the solution is also at its minimum.
2. **Maximum Turgidity**: When solute potential is at its minimum, it can lead to maximum turgidity in plant cells, as the cells are less likely to lose water and maintain their shape.

### Step 5: Conclusion
- Therefore, the answer to the question is that minimum solute potential means both minimum solute concentration and maximum turgidity.

### Final Answer:
Minimum solute potential means both minimum solute concentration and maximum turgidity.
