osmosis practice activity
osmosis is the diffusion of water from an area of high concentration to an area of low concentration. only water moves in osmosis! the diagrams below show the concentration of water and salt inside the cell and the concentration of water and salt surrounding the cell. complete the sentences below by comparing the concentration of the water inside the cell and the concentration outside the cell.

water will flow (into the cell, out of the cell, in both directions).
the cell will (shrink, burst, stay the same).

Explanation:

Step1: Recall osmosis and tonicity concepts

Osmosis is water - movement from high to low water concentration. Isotonic solutions have equal solute concentrations inside and outside the cell, hypotonic has lower solute outside (more water), and hypertonic has higher solute outside (less water).

Step2: Analyze cell - swelling

A cell swells in a hypotonic solution as water moves into the cell.

Step3: Analyze cell - shape stability

An isotonic solution doesn't change the shape of a cell as there is no net water movement.

Step4: Analyze osmosis causation

All three types of solutions (isotonic, hypotonic, hypertonic) can cause osmosis as there is a water - concentration gradient.

Step5: Analyze cell - shrinking

A cell shrinks in a hypertonic solution as water moves out of the cell.

Step6: Analyze transport in diagrams

For CO₂ movement from high to low levels, it's diffusion. For water movement based on concentration gradients, it's osmosis. For glucose movement from high to low concentration, it's diffusion. When water is in equal concentration on both sides, it's equilibrium.

Step7: Analyze water flow in NaCl example

In the given NaCl - water concentration example, water will flow out of the cell as the outside has a lower water concentration (95% NaCl, 5% H₂O) compared to the inside (5% NaCl, 95% H₂O). The cell will shrink.
