✋Introduction
Diffusion: moving particles
In this lesson: I can explain that diffusion is the movement of particles of a substance from an area of higher to lower concentration. All substances, including the cell cytoplasm and substances within it, are made up of particles. These particles move in random directions and collide all the time.
