Hello. My name is Carter. I am a cell. I am going to take you through the life of a cell. Let's go!!
First before we go I need some water. Water can pass through me very easily because I have a semi-premeable membrane. That is how osmosis works. Oh no I'm going to be late for work. Follow me.
While I'm on my way to work I can tell you about diffusion. Diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout.
CELL OSMOSIS AND DIFFUSION
Right now I'm at work. We are working on our Osmosis and Diffusion board.
