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

What happens to a cell in a hypertonic solution?
It swells
It shrinks

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
What occurs in an isotonic solution?
Water moves into the cell only
Water moves out of the cell only
Water moves in and out of the cell at equal rates
The cell bursts
When is a cell most likely to burst?
In a hypertonic solution
In an isotonic solution
In a hypotonic solution
In a dry environment
What happens when water is added to preserved food in a hypertonic solution?
It remains preserved
The food becomes isotonic
Water enters the food cells until equilibrium is reached
The food dissolves
