concentrations of 0.0 mol dm3‚ 0.2 mol dm3‚ 0.4 mol dm3‚ 0.6 mol dm3 and 0.8 mol dm3 affect the osmolarity point of potato cells‚ where it is investigated how osmosis changes the weight of the potato cells‚ measured by the percentage change between the initial and final mass of the potato? Independent Variable: Increasing sucrose concentrations Dependant Variable: Mean percentage change in mass of potato cells All cells have a protective barrier‚ one which selectively allows substances to enter and exit

June 30th‚ 1940 changed the lives of everyone living on Guernsey. During World War II the Germans occupied the Channel Islands‚ Guernsey included. My book‚ The Guernsey Literary and Potato Peel Society‚ is an excellent example of historical fiction for three reasons‚ it tells about the occupation of the Channel Islands‚ how the islanders had to adapt their life during the occupation‚ and how their lives were changed because the occupation. “Late in the afternoon of June 28‚ 1940‚ six Heinkel bombers

Title of Lab: Preparation and Assay of Phenolase and Peroxidase from Sweet and Irish Potato Hypothesis: Polyphenol Oxidase enzyme activity can be detected by change in colour of solution‚ Inhibitors prevent the reaction of the enzymes with substrates‚ the enzyme is relatively specific. Aim: To design and conduct an experiment to demonstrate enzyme activity of Polyphenol Oxidase and Peroxidase when mixed with catechol‚ caffeic acid‚ pyrogallad‚ tyrosine‚ guacol‚ and water‚ to test the effect of

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation

My group and I are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads
