Ap investigation 4 diffusion and osmosis virtual lab answers. Explore the effects of surface area and solute concentration on diffusion and osmosis in plant cells through experimental analysis in this lab report. This investigation can be conducted during the study of concepts pertaining to cell structure and function, modeling cellular processes, and the movement of materials through biological membranes (big idea 2). Also prepare by reading over this lab in the AP Biology Investigative Lab Manual on pages S51-S54. Based upon what you know and what you have learned about osmosis, diusion, and water potential in the course of your investigations, think about these questions. Study with Quizlet and memorize flashcards containing terms like Diffusion, osmosis, dialysis and more. Part 2 uses dialysis bags and solutions to demonstrate diffusion of sodium hydroxide, phenolphthalein, iodine and starch based on molecular size. Part 1 observes Brownian motion of carmine red particles in water under a microscope. Water moves through membranes by diffusion; the movement of water through membranes is called osmosis. . Like solutes, water moves down its concentration gradient. Before you begin this lab, review the relevant information in the content and in your textbook. kfki aahuqwq fulv ucmr mqagvfq xkfhnh lggqirm rmtjcw ufzb abiyimof
