Potato slices were placed in sucrose solution . After half an hour, density of sucrose solution increased . Water potential of Pototo tuber is

Options

A. Equal to solute potential of sucrose solution
B. Greater then sloute potential of sucrose solutioin
C. Less then solute potential of sucrose solution
D. Half the concentration of sucrose solution

Explanation

**Step-by-Step Solution:**

1. **Understanding the Scenario**: Potato slices are placed in a sucrose solution. After some time, the density of the sucrose solution increases. This indicates that the concentration of solutes in the sucrose solution has increased due to the movement of water.

2. **Identifying the Type of Solution**: The sucrose solution is hypertonic compared to the potato tuber. A hypertonic solution has a higher concentration of solutes compared to the inside of the potato cells.

3. **Movement of Water**: In a hypertonic solution, water moves out of the potato cells into the surrounding solution. This process is known as exosmosis. Water moves from an area of higher water potential (inside the potato) to an area of lower water potential (the sucrose solution).

4. **Effect on Potato Slices**: As water exits the potato slices, they lose mass. This loss of water from the potato cells results in an increase in the density of the sucrose solution, as more solute (sucrose) remains in the solution after water leaves.

5. **Comparing Water Potentials**: Since water is moving out of the potato tuber, it indicates that the water potential of the potato is less than that of the sucrose solution. Therefore, the water potential of the potato tuber is less than the solute potential of the sucrose solution.

6. **Conclusion**: Based on the analysis, the correct answer is that the water potential of the potato tuber is less than the solute potential of the sucrose solution.

**Final Answer**: The water potential of the potato tuber is less than the solute potential of the sucrose solution (Option 3).
