Amount by which water potential is reduced due to presence of solute is called

Options

A. Pressure potential
B. Solute potential
C. Mateic potential
D. None of the above

Answer

To solve the question "Amount by which water potential is reduced due to presence of solute is called," we will analyze the options provided and determine the correct answer step by step.

### Step 1: Understand Water Potential
Water potential (Ψ) is a measure of the potential energy in water, influencing the movement of water in plants. It is affected by two main components: solute potential (osmotic potential) and pressure potential.

**Hint:** Water potential is influenced by solutes and pressure.

### Step 2: Analyze the Options
1. **Pressure Potential**: This is the physical pressure exerted by the cell wall against the water inside the cell. It is a component of water potential but does not directly relate to the reduction of water potential due to solutes.

**Hint:** Pressure potential relates to mechanical pressure, not solute concentration.

2. **Solute Potential**: Also known as osmotic potential, this refers to the reduction in water potential due to the presence of solutes. When solutes are added to water, it decreases the water potential, making it more negative.

**Hint:** Solute potential is directly related to the presence of solutes and their effect on water potential.

3. **Matric Potential**: This is the potential of water to move due to its adhesion to solid surfaces (like soil particles). It is not directly related to the solute concentration in a plant cell.

**Hint:** Matric potential involves water's interaction with surfaces, not solutes.

4. **None of the Above**: This option implies that none of the previous answers are correct.

**Hint:** Consider if any of the previous options accurately describe the reduction of water potential due to solutes.

### Step 3: Conclusion
After analyzing the options, we find that the correct answer is **solute potential**. This is the term that specifically describes the reduction in water potential due to the presence of solutes in a solution.

**Final Answer:** Solute potential
