If the cell is placed in hypotonic solution, what will happen?

Options

A. Endosmosis
B. Deplasmolysis
C. Exosmosis
D. No change

Answer

### Step-by-Step Solution:

1. **Define Hypotonic Solution**: A hypotonic solution is one that has a lower concentration of solutes compared to the inside of a cell. This means it has a higher concentration of water.

2. **Understand Osmosis**: Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration (hypotonic solution) to an area of higher solute concentration (inside the cell).

3. **Cell Placement in Hypotonic Solution**: When a cell is placed in a hypotonic solution, the concentration of solutes outside the cell is lower than that inside the cell.

4. **Water Movement**: Due to osmosis, water will move from the hypotonic solution into the cell. This movement occurs because the cell's interior has a higher concentration of solutes, and water moves to balance the concentration on both sides of the membrane.

5. **Result of Water Entry**: As water enters the cell, it causes the cell to swell. If too much water enters, the cell may eventually burst, a process known as lysis.

6. **Specific Process**: The specific process of water entering the cell is termed "endosmosis," which refers to the inward movement of water.

7. **Conclusion**: Therefore, when a cell is placed in a hypotonic solution, the correct answer is that endosmosis occurs, leading to the cell potentially bursting.

### Final Answer:
The correct option is **endosmosis**.
