The Growth in Potato Production and Inception of Secondary Potato Markets in India Case Study: McCain India Limited Potatoes are a staple food crop in most developed and developing nations. The original habitat of South America was discovered by Europeans when Columbus landed on Latin American soil. However‚ the potato was adapted as a field crop only during the late 16th and early 17th century1. Global

Osmosis in Potato Conclusion The data we had did not support the definition of Osmosis‚ Osmosis is the diffusion of water through a partially permeable membrane from a region of lower solute concentration to a region of higher solute concentration; the data we collected did not seem to fit into this. The potato chips were suppose to lose more mass in the higher concentrated solution as the water from the potato chip will flow out to the higher concentrated solution as the water inside the potato has a

enzyme breaks H2O2 into water and oxygen. The production of the oxygen gas bubbles serves as evidence that the catalase enzyme is working. As catalase is breaking the bonds between H2O2‚ it is releasing energy in the form of heat which is reason for the warmth of the bubbles during the reaction. Starch acts to trap these bubbles and this creates a relatively stable foam that can be measured. ANALYSIS QUESTIONS 1. a) Describe the effect of damaging the potato on the catalase activity

The Irish potato clones were certainly low on genetic variation‚ so when the environment changed and a potato disease swept through the country in the 1840s‚ the potatoes (and the people who depended upon them) were devastated.Thesis: The Irish Potato Famine devastated the Irish population and economy as well as sowing the seeds of rebellion against England. 1st Point: Ireland dependent on potato • Families spent most time on cash crops to pay rent • Potato easy to grow‚ nutricious

GCSE Biology: Osmosis in a Potato Aim To investigate the effect of placing a piece of potato in a given strength of sugar solution. Prediction I predict that‚ as the solution becomes more concentrated the more the cell will shrink‚ as the water‚ of higher concentration inside the potato cells‚ flows down a concentration gradient into the solution‚ which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict

Battery from Potato Introduction: Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem: Can Potato be used to generate

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product
