Osmosis and Diffusion Quiz

What is osmosis?

• The movement of solute particles from an area of higher concentration to lower concentration.

• The movement of particles that requires energy.

• The movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution.

• The movement of particles from lower to higher concentration.

What is diffusion?

• The movement of particles from lower to higher concentration.

• The movement of particles that requires energy.

• The movement of particles from an area of higher concentration to lower concentration.

• The movement of solvent particles across a semipermeable membrane.

Which of the following is an example of osmosis?

• Movement of small molecules across a cell membrane.

• Red blood cells swelling up when exposed to fresh water.

• Perfume filling a whole room.

• Adding a drop of food coloring to water.

Which of the following is an example of diffusion?

• Soaking gummy candies in water.

• Plant root hairs taking up water.

• Adding a drop of food coloring to water.

• Red blood cells swelling up when exposed to fresh water.

What is a key difference between osmosis and diffusion?

• Osmosis occurs in gases, while diffusion occurs in liquids.

• Osmosis requires energy, while diffusion does not.

• In osmosis, both solvent and solute particles move, while in diffusion, only solvent particles move.

• Osmosis always occurs across a semipermeable membrane, while diffusion can occur in any mixture.

What is a similarity between osmosis and diffusion?

• Both processes involve the movement of solvent particles only.

• Both processes occur only across a semipermeable membrane.

• Both processes require energy to occur.

• Both processes act to equalize the concentration of a solution.

In osmosis, what moves across the semipermeable membrane?

• Neither solute nor solvent particles

• Solute particles

• Both solute and solvent particles

• Solvent particles

What happens to red blood cells in fresh water due to osmosis?

• They dissolve.

• They shrink.

• They swell up.

• They remain the same.

What is the main purpose of osmosis and diffusion?

• To increase concentration.

• To equalize concentration.

• To create energy.

• To separate particles.

Which process can occur in any mixture?

• Neither osmosis nor diffusion

• Osmosis

• Both osmosis and diffusion

• Diffusion
