Verified step by step guidance

Identify the concentration gradient: The image shows a cell with a 75% solute concentration inside and a 10% solute concentration outside. This indicates a concentration gradient across the cell membrane.

Understand osmosis: Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Predict water movement: Given the concentration gradient, water will move from the area of lower solute concentration (outside the cell) to the area of higher solute concentration (inside the cell) to balance the solute concentrations.

Consider the cell membrane's permeability: The cell membrane is selectively permeable, allowing water to move freely while controlling the movement of solutes.

Conclude the direction of water movement: Based on the principles of osmosis and the concentration gradient, water will move into the cell.
