State whether the following statements are true or false. Boiled potato tuber cannot be used for potato osmoscope experiment.
A. True
B. False

Answer

To determine whether the statement "Boiled potato tuber cannot be used for potato osmoscope experiment" is true or false, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding the Potato Osmoscope Experiment**:
- The potato osmoscope experiment is designed to demonstrate the process of osmosis, which involves the movement of water across a semi-permeable membrane.

2. **Effect of Boiling on Potato Cells**:
- When a potato tuber is boiled, the high temperature causes the cells within the potato to undergo denaturation. This means that the cellular structures and membranes are damaged.

3. **State of Cells After Boiling**:
- The cells in a boiled potato tuber are dead. Since they are no longer living, they cannot perform any biological functions, including osmosis.

4. **Osmosis Requirement**:
- For osmosis to occur, the cells must be alive and functional. Living cells can regulate the movement of water and solutes across their membranes.

5. **Conclusion**:
- Since boiled potato cells are dead and cannot undergo osmosis, they cannot be used in the potato osmoscope experiment. Therefore, the statement is true.

### Final Answer:
A. True
