Cell Membrane and Transport
This reinforcement worksheet displays a graphic of the cell membrane showing the phospholipid bilayer and embedded proteins. Students identify structures within the bilayer and use reasoning to determine how molecules are moving across the membrane in response to a hypertonic solution. Worksheet was designed for freshman level biology classes who are studying osmosis and…
