PPT-Osmosis and Water Potential of a Potato

Emma Macadam And Marc Brunton Hypothesis Our hypothesis is that the potato will have the highest water potential than the butternut squash sweet potato and the apple assuming it has the lowest sucrose .

Pharm. 5211: Section B. The Cell in its Environment. Ch 7, Section 2. L3 Biology. Molecules are always moving. Molecules move randomly and bump into each other and other barriers. Diffusion. Movement of molecules from an area of high concentration to an area of lower concentration . . Really smelly demonstration…... Put a few drops of vanilla in a balloon. Shake the balloon, then wait about 30 seconds. Smell the outside of the balloon. What’s going on?. EVIDENCE. INFERENCE. Complete problems: . You will be timed. THIS IS OUR LAST COMPLETION ALA. (We will begin grading for correctness after the break.) . Agenda. Catalyst (10 minutes). SWAT (7 minutes) . Review Slides (5 minutes). Diffusion. Movement of particles from HIGH to LOW concentration.. Caused by a . concentration gradient . (difference in concentration).. Stops when it reaches . dynamic equilibrium. (equal amounts everywhere). . Sec 4.3 . pg. 74-75. Osmosis. : . a . special case of diffusion . involving water. water . molecules . move across . a selectively permeable membrane from an area of high water concentration to an area of low water . Root Hair Cells . Roots do more than just anchor the plant in the ground, . they take up water and mineral salts . from the soil. . The surface of the cells have specialised root hair cells with long thin extensions that reach into the surrounding soil. . Good practice for test-taking strategy, too.. By the end of this lesson…. You should be able to solve word problems that require analysis of . osmosis scenarios.. #1. If you soak your hands in dishwater, you may notice that your skin absorbs water and swells into wrinkles.
