Cards for diffusion, osmosis and active transport Flashcards
1
Q
Diffusion
A
Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration.
2
Q
Osmosis
A
Where only water moves across a partially permeable membrane from a dilute solution to a concentrated solution.
3
Q
Active transport
A
The movement of molecules or ions across a cell membrane in a region of higher concentration, assisted by Enzymes and requiring energy
