AP Biology Lab #4 Passive Transport

What is the movement of solutes from an area of high concentration to an area of low concentration called?

• Osmosis

• Diffusion

• Active transport

• Facilitated diffusion

What is the process by which water moves through a selectively permeable membrane?

• Diffusion

• Active transport

• Osmosis

• Endocytosis

Which of the following is NOT a factor that affects the rate of diffusion?

• Temperature

• Concentration gradient

• Surface area

• Cell volume

In which direction does water move in osmosis?

• From an area of high water concentration to low water concentration

• From an area of low water concentration to high water concentration

• From an area of high solute concentration to low solute concentration

• From an area of low solute concentration to high solute concentration

What is the term used to describe a solution with a higher solute concentration and lower water potential compared to another solution?

• Hypotonic

• Hypertonic

• Isotonic

• Osmotic

What is the solute potential also known as?

• Osmotic potential

• Pressure potential

• Water potential

• Turgor pressure

What happens to a plant cell when it is placed in a hypertonic solution?

• It swells and may burst

• It shrinks or undergoes crenation

• It loses turgor pressure

• It remains unchanged

What is the process called when a plant cell loses water and the cell membrane shrinks away from the cell wall?

• Plasmolysis

• Crenation

• Lysis

• Turgor pressure

What is the purpose of using dialysis tubing in modeling living cells?

• To simulate the movement of water in plant cells

• To demonstrate the process of diffusion

• To measure the rate of osmosis

• To observe the effects of solute concentration on cell shape

What is the effect of adding solute to the water surrounding a plant cell?

• Water will move into the cell

• Water will move out of the cell

• There will be no net movement of water

• The solute concentration inside and outside the cell will be equal
