Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.

In diffusion a substance moves from a high concentration to a lower one. In active transport it is the opposite, the substance moves from a low to a high concentration. Active transport always...
1 Diffusion (which includes facilitated diffusion) and osmosis are passive. This means that they do not require any energy input; they go ahead spontaneously. Diffusion happens in a cup of tea,...
