1
Q
What is diffusion?
A
Diffusion is a passive transport process. Diffusion is the movement of molecules from regions of high to low concentration .
2
Q
What is passive cell transport?
A
Meaning it doesn’t require any energy.e.g. Diffusion and osmosis
3
Q
What is active cell transport
A
Meaning it requires energy e.g. ion pumps and cytosis
4
Q
What is 2 way diffusion?
A
Is when 2 gasses or 2 liquids cross
5
Q
What is equilibrium? (Regarding diffusion)
A
This is when the substance or room has an even coverage.e.g.icing on a cake, a colouring in, the gas in a room.
6
Q
