Diffusion Animation (Short and Sweet version)

Transcript:
One of the most important processes in biology is diffusion. In diffusion, particles move from high concentration to low concentration. Another way to say this is that they move DOWN THEIR CONCENTRATION GRADIENT. This process is passive, meaning that NO energy is used by the cell to make it happen.
Diffusion happens because molecules are in constant random motion.
Notice that the molecules move around randomly in every direction, but that overall they move from high to low concentration until there are roughly equal concentrations on both sides of the membrane, a condition known as dynamic equilibrium.

Nice explanation of terms and the animation shows diffusion well.

Can you make videos on photosynthesis? Thx
