What is diffusion?
The movement of particles from an area of high concentration to an area of low concentration
What is osmosis?
The movement of water across a selectively permeable membrane from an area of low solute concentration to high solute concentration
Where does osmosis occur in animal cells?
In the cell membrane of animal cells
Where does osmosis occur in plant cells?
In the cell membrane and vacuoles of plant cells
What is active transport?
The movement of substances across cell membranes against a concentration gradient
What is the difference between active transport and passive transport?
Active transport requires energy, while passive transport does not
What are examples of active transport?
Examples include the uptake of glucose and ions in cells
