Structure of the Cell Membrane - Active and Passive Transport
What is it that separates what's inside a cell from what's outside of a cell? Why, that's the cell membrane. What's it made out of? How does it work? How do molecules get in and out of the cell? These are super-important concepts! Let's...

BIOLOGY - Cells - Diffusion and Osmosis
In this video we are going to discover how cells take in useful substances and remove waste using three methods of transportation: diffusion, osmosis and then in the second part we will look at active transport. The exchange of materials...

Prokaryotic Cells: The Simplest Kind of Life
We've established that the basic unit of life is the cell, and that the simplest forms of life are just one cell. The earliest unicellular organisms were prokaryotic, and there are many prokaryotic organisms still around today, including...
