A student observes that a plant cell placed in a hypertonic solution shrinks. Which process is responsible for this observation?

• Active transport

• Osmosis

• Endocytosis

• Exocytosis

Which scenario best demonstrates diffusion?

• Water moving into a cell through a membrane

• Oxygen moving from an area of high concentration to low concentration in the lungs

• Glucose being pumped into a cell using energy

• A cell engulfing a large particle

A red blood cell is placed in a hypotonic solution. What will most likely happen to the cell?

• It will shrink

• It will swell and possibly burst

• It will remain the same size

• It will divide

A scientist places a cell in an isotonic solution. Predict what will happen to the movement of water across the cell membrane.

• Water will only move into the cell

• Water will only move out of the cell

• Water will move in and out at equal rates

• Water will not move at all

A student is given three solutions: pure water, a 5% salt solution, and a 10% salt solution. They place identical plant cells in each solution. Which solution will cause the greatest loss of water from the plant cells, and why?

• Pure water, because it is hypotonic to the cell

• 5% salt solution, because it is isotonic to the cell

• 10% salt solution, because it is hypertonic to the cell

• All solutions will have the same effect
