Mr andersen shows you how to properly core potatoes for the osmosis lab a thorough description of the lab protocol is included along with a brief descripti. Diffusion and osmosis occur between different molar solutions until the solutions are isotonic, effecting the turgor pressure of plant cells lab 1c – the materials used in conducting this experiment are as follows: six 250ml glass beakers, a potato, a core borer, a knife, distilled water, , 02m, 04m, 06m, 08m, and 10m.
Water potential should be about constant for the one type of potato experimented on this cannot be calculated because we did not experiment on other plants osmosis and water lost changed because the outer solution had varying levels of solute sucrose however, when comparing with other lab groups' data, water. Molecules are always on the move thanks to kinetic energy this energy makes diffusion and osmosis possible, two processes used by cells to maintain homeostasis in this lab, we'll look how osmosis and diffusion work and what factors affect them. Through osmosis, the solution moved along the concentration gradient and into the potato slice making it hypotonic ap biology august 23, 2012 egg osmosis lab definition of osmosis: the diffusion of water across a selectively permeable membrane from high to low concentrations hypothesis: if i place.
Title: osmosis and diffusion lab introduction: diffusion is the passive movement of molecules from an area of higher concentrationof these molecu the potato cores placed in varying concentrations of sucrose solutions will have different percent changes in mass depending on the water potential and water concentration. In this lab, you will observe the process of osmosis and diffusion you will also learn how to calculate water potential if you are not familiar with these concepts, make sure that you have looked them up in your textbook if you don't know what these terms mean, this lab is not going to make sense to you. This lab is derived from the ap biology lab on diffusion & osmosis one segment of the lab is the classic starch /iki / glucose / dialysis tubing experiment, and the other uses core samples of potato in varying concentrations of sugar-water to measure water potential of the potato cells data is collected and analyzed by using.
