Student Exploration Osmosis Gizmo Answers ((exclusive))

A hypertonic solution has a higher solute concentration than the cell, causing it to shrink. A hypotonic solution has a lower solute concentration, causing the cell to swell. Gizmo Warm-up: Observing the Simulation

Osmosis is the movement of water molecules from a region of high concentration to a region of low concentration through a selectively permeable membrane. This process helps regulate the balance of fluids within cells.

When you press "Play," the cell will either expand or shrink depending on the initial settings of the sliders. What is Osmosis? - FutureLearn student exploration osmosis gizmo answers

$$ \textA steeper concentration gradient increases the rate of osmosis. $$

| Scenario (Side A → Side B) | Solute Concentration | Water will move… | Prediction (→ / ← / no net) | Gizmo result | Correct? | |----------------------------|----------------------|------------------|-----------------------------|--------------|-----------| | A: pure water, B: 10% salt | A: low solute, B: high solute | Toward higher solute (B) | → B | | | | A: 5% glucose, B: 10% glucose | | | | | | | A: 20% starch, B: 5% starch | | | | | | | A: 0% NaCl, B: 0% NaCl | | | | | | | A: 15% sucrose, B: 15% sucrose | | | | | | A hypertonic solution has a higher solute concentration

The movement of solvent particles (usually water) across a semipermeable membrane from an area of high solvent concentration to an area of low solvent concentration.

Only the green solvent particles move freely across the cell wall. This process helps regulate the balance of fluids

$$ \textThe cell shrinks as water molecules flow out of the cell. $$
