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 - Active Transport
In the first part of this video we looked at diffusion to move gases and osmosis for the movement of water, from high concentration to low concentration down their concentration gradient. Active transport works in the opposite...

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...

Understanding Active Transport in Cells
This video explains the concept of active transport, comparing it to the movement of smoke from an area of low concentration to an area of high concentration. This video is part of the 14-part series, Cell Processes.

Small intestine and food absorption
Small intestine and food absorption Digestion goes hand in hand with absorption… which happens in your small intestine. Which is what we’re going to look at in this video. So keep watching!

Sophia: Diffusion: Lesson 3
This lesson explains the process of diffusion. It explains how diffusion is a passive form of transport, used to move molecules down their concentration gradient. It is 3 of 8 in the series titled "Diffusion."
Sophia Learning
Sophia: Osmosis: Lesson 3
This lesson explains the process of osmosis. It explains how osmosis is a passive form of transport, used to move water molecules across a semi-permeable membrane, down their concentration gradient. It is 3 of 8 in the series titled...
