When a cell is placed in hypotonic solution, water moves into the cell, this flow is called..................................

Explanation

**Step-by-Step Solution:**

1. **Understanding Hypotonic Solution**: A hypotonic solution is one where the concentration of solutes outside the cell is lower than the concentration of solutes inside the cell. This means that the external solution has a higher concentration of water (solvent) compared to the solute.

2. **Water Movement**: When a cell is placed in a hypotonic solution, water moves into the cell. This movement occurs because water naturally flows from an area of lower solute concentration (hypotonic solution) to an area of higher solute concentration (inside the cell).

3. **Direction of Flow**: The flow of water is directed towards the area with higher solute concentration. In this case, since the cell has a higher concentration of solutes compared to the surrounding hypotonic solution, water will move into the cell.
