cells cannot make energy, but they can change energy from one form to the other
respiration
process by which living organisms take in oxygen and use it to make energy, cells break down food and use it for energy
aerobic respiration
it requires oxygen to make energy
anaerobic respiration
it does not need oxygen
anaerobic respiration
it does not need oxygen
diffusion
the process by which particles move from an area of high concentration to an area of low concentration
diffusion
the process by which particles move from an area of high concentration to an area of low concentration
osmosis
the diffusion of water, or water moving form an area of high concentration to low concentration
active transport
movement from an area of low concentration to high concentration using a carrier molecule and energy
