This worksheet was designed for an introductory biology course to reinforce concepts related to cell transport. An image shows the phospholipid bilayer with embedded proteins with text that describes how small molecules like oxygen move across the membrane by diffusion.
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. After coloring the images, students find information in the text to answer a set of questions about cell transport.
