change‚ means there is no net loss or gain of water. Introduction This study shares the results of an effort to understand diffusion and osmosis in general. It focused more into osmosis in plants cell‚ and how to indirectly measure osmolarity in potato tuber tissue. Osmosis is the diffusion specifically of water across a membrane. Diffusion occurs when certain substance‚ such as an ion‚ is more concentrated on one side of membrane. If the membrane allows this ion through‚ the ions will move from

THE IRISH POTATO FAMINE Pre-Famine History The potato was introduced to Europe sometime in the 16th century. There are many theories on how it arrived‚ but the one with the most credibility is from a case study done by Theresa Purcell. She explains how the white potato‚ also known as the Irish potato‚ originated in the Andean Mountains and was brought to Europe by the Spaniards. The potato was originally classified in the same family as the poisonous nightshade so people refrained from eating

Potato Catalysis Lab Pre-Lab Assignment Background Information: An enzyme is catalytic protein. It is the most important type of molecule found in living cells. Cells would not be able to function without enzymes. Enzymes speed up or slow down chemical reactions of the cells. It is usually easy to identify the names of enzymes because they end in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals

Aim To observe and measure the effect of osmosis on the mass of potato using a starch solution. Introduction In order to measure the effect of osmosis‚ eighteen pieces of potato were cut and placed in six groups‚ each group of three pieces cut to weigh as close as possible to one another. For each potato group‚ a test tube was half filled with a starch solution varying in concentration from 0% (water) to 1%. Hypothesis Through osmosis

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

If you have never heard of Pop Chips‚ they are all-natural Potato Chips and are fantastic. As we make our way to the photoshoot‚ I had this weird feeling in my stomach. I think it was just the rush of excitement and nervousness getting to me. When we arrived‚ I was pulled straight out of my car and escorted to my dressing room‚ so we could get started ASAP.
