Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration

The Irish Potato Famine Have you ever thought that one day all of the potatoes could go bad? Unfortunately it’s true.The potato famine or known as the Great hunger was in Ireland until 1845-49. People of all ages were affected.Since the soil was poor‚ potatoes didn’t grow like they’re supposted to. The cause‚ a failure of the Irish potato crop due to an infestation of Phytophora infestans‚ a microscopic fungus‚ also called the potato blight.They think that the disease was brought him by an American

A potato chip is a slice of potato‚ deep fried or baked until crisp. Potato chips serve as a side dish or snack. The chips of this kind are just cooked and saled‚ but chips are an important part of the snack food market in English-speaking countries and many other Western nations. Lays Classic potato chips contain potatoes‚ healthier oil‚ and salt. Consumers buy lays classic potato chips because of the fufilling taste‚ crunchy and salty. Lays’ potato chips have become such a common snack among many

experiment is to study how enzyme activity is affected by environmental conditions. Researchers tested the level of potato extract enzyme activity with 1-11 pH‚ varying temperature‚ catechol solution‚ hydroquinone solution‚ and different measurements of catechol. In Figure 1A and 1B‚ pH levels were tested with potato extract to see how pH would affect the amount of Benzoquinone is formed in the potato. Although it was hypothesized that enzymes would form Benzoquinone better in acidic pH levels‚ the absorbency

modern society our perspectives on issues have altered. Out of the many of the push factors that Ireland was faced with the “Great Potato Famine” was the basis for many people immigrating. Many other reasons that the Irish had begun to immigrate were from political reasons‚ rising poverty levels‚ and spread of disease. The famine during 1847- 1852‚ lead to the potato harvest to fail year after year. This resulted in the increase of food cost‚ forcing the middle class to become poor. This issue had
