Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered

This was conducted through four different experiments. The first tested the effect of temperature on enzyme activity. The independent variable in the first experiment was the temperature of the solution of pH 7 buffer‚ potato juice‚ and the enzyme. The independent variable for the second experiment was the pH of the phosphate buffer. The independent variable for the third experiment was the enzyme concentration of the solution‚ and finally the independent variable of the

B. Yeats‚ 1921 TEACHER ’S INTRODUCTION Between 1845 and 1850‚ more than a million Irish people starved to death while massive quantities of food were being exported from their country. A half million were evicted from their homes during the potato blight‚ and a million and a half emigrated to America‚ Britain and Australia‚ often on-board rotting‚ overcrowded "coffin ships". This is the story of how that immense tragedy came to pass. The necessary historical and political context for a

variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled variables are the amount of water‚ amount of salt‚ and the size of the potato. If the potato is placed in a higher salt concentration‚ then the potato will decrease its size. We started the lab by cutting the potato core length (44

had two sized potatoes‚ 6g and 10g‚ and placed each in three different dilutions of sucrose at 0.5M‚ 0.1M‚ and 0.05M. We also placed a 6g and 10g potato piece in water to act as a control. Based on the weight percent change over 60 minutes‚ the 6g potato piece had faster water movement than the 10g. This confirms out hypothesis that smaller potato pieces will have a faster rate of water movement. Introduction Osmosis is the diffusion of water across a selectively permeable membrane. Water
