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 . Lab 4: Diffusion and Osmosis. PROBLEM . – What about physical pressure? . AIM: Describe the process of passive transport (diffusion across the membrane).. . It is easy to say that water will move from high concentration to low concentration…but look at the cell to the right…. Facilitated Diffusion, Osmosis and Active Transport. Passive Transport. Learning Objectives. - explain what is meant by passive transport . - compare diffusion and facilitated diffusion . Identify the role of membrane proteins in transport. Pharmaceutical Use. Water Purification Engineering . Md. . Saifuzzaman. Associate Professor. Pharmacy Discipline, KU.. E-mail: saifuzzaman17@yahoo.com. Pharmaceutical Industrial Management . Pharm. 5211: Section B. CHAPTER 2/ O’LEVEL BIOLOGY 5090 / GCE.. 2. Diffusion and osmosis. Content. 2.1 Diffusion. 2.2 Osmosis. 2.3 Active . transport. Learning outcomes. Candidates should be able to:. (a) define diffusion as the movement of molecules from a region of their higher concentration to a region of. A Review of Osmosis and Diffusion. Last week we discussed the two passive processes known as osmosis and diffusion. . Let’s see if you remember the difference between the two!. The following picture best describes the process of:. . 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. Water . is one of the most important substances on earth. All plants and animals must have water to survive. If there was no water there would be no life on earth.. Apart from drinking it to survive, people have many other uses for water. These include. A liquid in which a substance dissolves. Solvent. Water. MOLECULAR MOVEMENT. Nature adores balance. Wind. Hot air moving toward cold air. Wicking. Water moving from wet to dry. MOLECULAR MOVEMENT. Movement of molecules from . Using a pot model to represent osmosis . Plants and water. Plants take up water through their roots, from the soil.. But . how. does this happen?. Learning outcomes . You will be able to…. explain the overall movement of water into and out of plant cells . Using a pot model to represent osmosis . Plants and water. Plants take up water through their roots, from the soil.. But . how. does this happen?. Learning outcomes . You will be able to…. explain the overall movement of water into and out of plant cells . 2. Diffusion and osmosis. Content. 2.1 Diffusion. 2.2 Osmosis. 2.3 Active . transport. Learning outcomes. Candidates should be able to:. (a) define diffusion as the movement of molecules from a region of their higher concentration to a region of. …happens across a semi-permeable membrane. . ONLY WATER. Water is a small but extremely important molecule that makes up most of the liquid part of the cytoplasm in living things. . . Deals . ONLY. Investigate the effect of a range of concentrations of salt or sugar solutions on the mass of plant tissue.. Osmosis is the movement of water through a selectively permeable membrane. The water moves from an area of high concentration of water to an area of lower concentration of water. . Dr. Habibur Rahman. Associate Professor. J. N. College, Boko. Water Absorption: Organ, Mechanism: . Absorption of water and nutrient is carried by the younger portions of a root, near its tip. The very tip is covered with a sheathing root cap which protects the delicate underlying tissues as the root pushes its way through the soil..
