The APsolute Recap: Biology Edition - Osmosis and Water Potential
“Water water everywhere, nor any drop to drink.” Episode 30 reviews the passive transport of water and the calculation of water potential - with many water sound effects! Hypertonic solutions have a greater concentration of solutes than a hypotonic solution (1:30). It does not end well for a paramecium placed in freshwater (2:15). Water potential allows us to predict the movement of water (4:00) and is measured in bars. Don’t memorize any equations! (5:20)
The Question of the Day asks (6:56) “What is the process called when a cell membrane pulls away from a plant cell wall after being placed in a hypertonic solution?”
