Color the cell membrane with a focus on diffusion, osmosis and transport proteins. Students color the structures of a cell membrane according to the directions. Then they answer questions about cell transport.

I designed this worksheet for an introductory biology course to reinforce concepts related to cell transport. An image shows the phospholipid bilayer with embedded proteins. The graphic shows phospholipids, transport proteins, and molecules. Oxygen is depicted as a double circle (O2) and glucose as a hexagon (C6).

The text describes how small molecules like oxygen move across the membrane by diffusion. Other molecules may use channel proteins to pass through the cell membrane.

The second page focuses on another type of passive transport: osmosis. Students also color this image and text explains the difference between hypertonic and hypotonic solutions. A diagram shows the movement of water across the cell membrane. Water will move to areas that have a higher solute concentration.
