#1
Front (Question)
what is diffusion
Back (Answer)
movement of particles from high concentration to low concentration down a concentration gradient
#2
Front (Question)
what is osmosis
Back (Answer)
movement of water particles from high water potential(dilute) to low water potential(concentrated) across a partially permeable membrane
#3
Front (Question)
what is active transport
Back (Answer)
movement of molecules from their lower concentration to their higher concentration, against a concentration gradient, using energy from respiration
