Osmosis

What is diffusion?

• The movement of particles from a lower concentration to a higher concentration

• The movement of particles from a higher concentration to a lower concentration

• The movement of water through a selectively permeable membrane

• The shrinking of a cell due to water loss

How does osmosis differ from diffusion?

• Osmosis involves solutes, while diffusion involves water

• Osmosis requires energy, while diffusion does not

• Osmosis involves water, while diffusion involves various atoms, ions or molecules

• Osmosis occurs in gases, while diffusion occurs in liquids

Which of the following solutions has equal solute concentration inside and outside the cell?

• Hypertonic solution

• Hypotonic solution

• Isotonic solution

• None of the above

What happens to a cell in a hypertonic solution?

• It swells

• It shrinks

• It remains the same

• It bursts

Which of the following is the solvent in a lemonade solution?

• Lemon

• Sugar

• Water

• Lemonade

What will happen to a raisin placed in water?

• It will shrink

• It will swell

• It will remain unchanged

• It will dissolve

In which type of solution does water move into the cell, causing it to swell?

• Isotonic

• Hypertonic

• Hypotonic

• Osmotic

What is the process called when water moves from an area of low solute concentration to high solute concentration through a membrane?

• Diffusion

• Filtration

• Osmosis

• Active transport

How is food preserved using the principles of osmosis?

• By adding water to the food

• By removing water from the food using a hypertonic solution

• By freezing the food

• By adding oxygen to the food

What is the main purpose of the cell membrane in osmosis?

• To allow all substances to pass freely

• To block all substances from passing

• To selectively allow substances to pass

• To dissolve the cell
