Osmosis using potato cores and sucrose solution 1.0 Abstract This experiment’s ultimate goal is to find the water potential of the potato cell. This was achieved through placing potato cores in different concentrations of sucrose (0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%‚ 2.0%‚ 3.0% and 4.0%) solution and to observe how much water was gained or lost through osmosis to reach a prediction of the concentration within the potato cell. The results displayed that the concentration of sucrose within the potato cell is

of a Potato Mishal Hasan Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation‚ several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it was isotonic. Anything above caused the potato to gain weight showing that it was a hypotonic solution and anything below caused the potato to lose

MY DISCOVERY OF IRELAND WHAT MAKES IRISH CULTURE POPULAR WORLDWIDE? ’I am of Ireland‚ And the Holy Land of Ireland‚ And time runs on‚’ cried she. ’Come out of charity‚ Come dance with me in Ireland.’ William Butler Yeats My first encounter with Ireland and its culture was rather trivial. I saw some Irish dancing and was fascinated by its rigor‚ energy‚ and emotional charge. I am not a dancer myself but Irish dances that I saw on TV made me want to get on my feet and start tap-dancing

diffusion I will be using potato discs‚ of the same size and mass‚ in different concentrations of sugar solution to find out whether the mass of the discs increases or decreases depending on the concentration. I predict that when the sugar solution is 0% the mass will increase as there is less sugar in the water than in the potato. The water will then travel through a partly permeable membrane into the potato from outside. When the sugar solution is 20% the mass of the potato will decrease as there

though the poet and his mother are having a good time peeling potatoes‚ his mother is ill and they are brought to their senses that the happy times will soon be brought to an end. 2. The potato is an important symbol in Ireland because of its value as a food staple and reminder of the terrible potato famine in the 19th century. What personal symbolic value does it have in this poem? In this poem the potatoe is a symbol of time shared with the poets mother‚ time when it is just him and his mother

Irish immigrants were a really really big part of the culture change. The largest wave of immigrants came from Ireland because of the famine in their land. Everyone ate potatoes over there‚ so when the crop got a fungus and they died‚ it was a huge problem for the Irish. A whole lot of people ended up dying from the lack of food. A lot of the Irish that came to America couldn’t do anything. They weren’t talented and they had no skills and no money. Mostly they lived up north in cities. They faced

Patrick’s Asylum. Almost all the children were sick‚ but the nuns called for brave and god-fearing souls to care for the most severely affected. That was the purpose of this place‚ “to gather and care for the Irish children‚ while waiting to place them in honest and charitable homes.6 The nuns asked only those truly willing to accept such a task‚ “it should be given freely and for the love of Jesus Christ.”7 The Sisters of charity fed and clothed these children

the solution is hypotonic‚ and water will move from the solution into the cell. If the surrounding solution has a higher concentration of dissolved molecules than the cell‚ the solution is hypertonic. In that case‚ water will move from the cell out into the surrounding solution. An isotonic solution is when the concentration of dissolved molecules is the same inside and outside the cell‚ and there is no net movement of water across the membrane. When cells are placed in a hypertonic solution‚ water

Jordan Marsh The first group of the old immigration I would like to discuss is the Irish. During the old immigration and they were treated as wild animals. They had to deal with poor wages for jobs and were discriminated against for their actions and beliefs. They left their homeland because of food shortages that caused starving and poverty. The potato famine caused many of these issues. They were hated and treated badly and had to deal with civil unrest‚ severe unemployment

Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1. Concentration of sucrose solution table Concentration/ M | Sucrose Solution/ ml | Distilled Water/ ml | 0 (Water) | 0 | 10 |
