Osmosis
What is the definition of osmosis?
The movement of water molecules from an area of high concentration to an area of low concentration
What is the role of a selectively permeable membrane in the process of osmosis?
It allows only certain molecules to pass through while blocking others
In which direction does water move during osmosis?
From an area of high water concentration to an area of low water concentration
From an area of low solute concentration to an area of high solute concentration
What is the process by which plants absorb water from the soil through osmosis?
Root pressure
What happens to a red blood cell when placed in a hypertonic solution?
It shrinks and shrivels up
Which of the following is an example of osmosis in everyday life?

What is the pressure that must be applied to a hypertonic solution to prevent the flow of water by osmosis called?
Osmotic pressure
What is the main difference between osmosis and diffusion?
Osmosis involves the movement of water molecules while diffusion involves the movement of solute molecules
