to survive on planet Mars in the future (Reader, 2009). Yet not many people know about how the potato affected many countries and where did the potato started to grow. Knowing the basics and history of potatoes can really influence the thought of when someone is eating a French fried potato. Going back to its history, the potato first settled in southern Peru, then causing the destruction the Irish Potato Famine, and potentially ending in future in another planet.

potential of a potato Aim Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis, by finding the difference in weight before and after the potato has been set in a solution of water, sugar or salt. Trial Method Firstly we collected the equipment. This included a scalpel, potato cutter, and test tubes. Then we cut the potato using the

eventually wipe out an eighth of the population. This became known as the potato famine, which lasted between 1845-1849. A mysterious blight attacked the potato crop, destroying the only real food of Ireland’s rural population. The blight caused by a mildew like fungus called Phytophthora infestans that infects the potato foliage and its tubers. Many believed the blight was caused by rainy, cool weather, which caused the potato to turn black and die. The blight attacked again and again over the next

Investigate the Rate of Osmosis in Different Vegetables (Carrot, Potato, Swede, Parsnip and Sweet Potato) In this coursework experiment I plan to find the rate of osmosis in different vegetables (Carrot, Potato, Swede, Parsnip and Sweet Potato). I will measure the mass before and after the experiment to use the results to calculate the rate of osmosis, and to find trends in the vegetables. To ensure the experiment is fair, I will control all the other variables (Temperature, size of chip at 5cm

The Irish Potato Famine and Primary Sources More than a million Irish people died during The Irish Potato famine that hit Ireland between 1845 to 1849 (Pollard, pg. 551). Potatoes were the primary diet of the Irish, especially the Irish Lump potato. When the fungal disease hit, known as “potato blight,” the Irish potato crops were lost. After reading primary sources regarding the Irish Potato Famine, the reader can visualize the horrors that the Irish people endured during the famine including

use. When a staple food is destroyed is can effect many people economically and by health. An invasive pathogen that was originated in Central Mexico that was very detrimental for potatoes was Phytophythora infestans. The disease is also known as potato late blight. Phytophythora infestans are

Ireland was flourishing with people, life overall was good. That would all take a radical turn, many lives would change due to the upcoming famine. From 1845 to 1848, it would become known as a turning point in Ireland's history. At this time, a potato famine had erupted within Ireland. It was caused due to a plant fungus that had ruined almost all of their crop. Of course, the plant fungus had always been a worry, but there was nothing that could be done about it. If farmers were looking for aiming

early nineteenth century in Ireland. A visit to the countryside would mean seeing endless rows of potato bushes in fields as far as the eye could see. The potato became the staple of Irish diet, with one-third of the population depending on the root by 1844. But within a year, more than half of the potato crops were destroyed by the blight and thus began the Irish Potato Famine. The failure of the potato crop and its subsequent starvation was attributable to one thing: monocropping. Ireland actually

solutions with different salt concentrations on the mass of a potato slice. The data collected and analyzed in this experiment seems to support the hypothesis, which stated that the mass of a potato slice would decrease, as the salt concentration increased. This can be evidenced in Graph 1 where the downward slope of the data shows a negative correlation between salt concentration and average percent change. During the experiment, only the potato slices placed in distilled water gained mass. Their mass

will a potato cube’s mass change if put in a mixture of Glucose and Salient together vs a potato cube just being put into a solution with Glucose or Salient. 3. Background Information: Diffusion is where particles move from areas of higher concentration to areas of lower concentration. Osmosis is the diffusion of water. Glucose (sugar) will not diffuse as much as Salient because there is already sugar inside of the potato so not as much water be affected by diffusion. Salient
