Controlled Assessment: Osmosis of a Potato [pic] Osmosis: Osmosis is the movement of substances through a partially/semi permeable membrane from an area of high concentration to an area of low concentration to balance of the concentration of the two sides. Biological membranes do allow water to pass through‚ but water will have no net movement unless osmosis takes place. Preliminary Method I have chosen to investigate the factor of the weight of potato strips after set amounts of time.

This is my first entry to my log of the Ice Cube experiment. I have yet to kickstart my new‚ or soon-to-be addiction; however‚ I am quite apprehensive with the entire situation at hand. The thought of having to continuously put in a conscious effort of consuming ice doesn’t seem too appealing in my opinion. Likewise‚ I’m also fearful of the looks and judgement I may get from onlookers who are unaware of the experiment. All in all‚ I will commit to this experiment to my fullest extent‚ regardless

The Effect of Salt Concentration on Osmosis in Potato Cells We should first explain what Osmosis is. It’s a passage of water from a region of high water concentration through membrane to a region of low water. Semi membrane is a very thin layer of material‚ which allows some things to pass through them but prevent other things from passing through. The cells allow small molecules like Oxygen‚ water‚ Carbon Dioxide‚ Ammonia. But will not allow larger molecules like Sucrose‚ Starch‚ or protein‚ etc

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

they do provide some sense of the issues to be faced. Second‚ diet problems that are missing the constraints that force variety into the diet can be terribly embarrassing. It has been said that a hospital in New Orleans ended up with an LP solution to feed each patient only castor oil for dinner because analysts neglected to add constraints forcing a well-rounded diet.

1) Irish Potato Famine. 1845-1849. Called the Great Famine. In the early 19th century‚ Ireland’s tenant farmers struggled to provide for themselves and to supply the British market with cereal crops. By the early 1840s half the Irish population‚ mostly the rural poor‚ became to depend almost exclusively on the potato for their diet. The rest of the population also consumed it in large quantities. A heavy reliance on just one or two high-yielding types of potato greatly reduced the

identify an unknown solution‚ based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or absence of a color change. Water was also used as a control solution‚ as it showed a negative reaction with the indicator solutions. Seven sets of three
