Verified step by step guidance

Identify the concentration of solutes inside and outside the cell. In the image, the outside solution has a 10% solute concentration, while the inside of the cell has a 0.1% solute concentration.

Understand the concept of tonicity, which refers to the ability of an extracellular solution to make water move into or out of a cell by osmosis.

Compare the solute concentrations: A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Determine the direction of water movement: Since the outside solution is 10% and the inside is 0.1%, water will move out of the cell to the area of higher solute concentration.

Conclude that the outside solution is hypertonic relative to the inside of the cell, as it has a higher solute concentration, leading to water exiting the cell.
