Conclusion and Discussion:
The purpose of the experiment was to find the osmolarity of sucrose in the potato tuber. Based on the result above the osmolarity of sucrose in the potato is around 0.2M to 0.3M. This mean the potato is in it isotonic stage around 0.3M, and hypotonic from 0.0M to 0.2M, hypertonic from 0.4M to 0.5M. Therefore, the hypothesis was wrong, the osmolarity of sucrose within the potato tuber tissue is between 0.2M to 0.3M.
Investigating the Concentration of Sucrose in Cells of Carrots and Potatoes Plan Introduction Osmosis is defined as 'the net movement of water molecules from a region of high water concentration to a region of lower water concentration through a partially permeable membrane'. In my experiment the process of osmosis will be due to the concentration of sucrose inside the cell compared to outside. Therefore if there is a higher concentration of sucrose molecules outside the cell then the net movement of water molecules will be out of the cell and similarly if there is a higher concentration of sucrose molecules inside the cell then the net movement of water molecules will be into the cell. This movement of water molecules causes the cells to become either turgid, which is when the cells are filled with water, or flaccid, which is when the cells are 'limp' with little water.
The Effects of Sucrose Molarity on Cells in the Stem Tuber of a Potato Planning In this investigation I am trying to find out what molarity of sucrose solution is same as the molarity of sucrose in the cells of a potato. In this experiment I am going to change the molarity of the sucrose solution out the cells of potato. I predict that if the molarity of sucrose solution outside the cells is isotonic to the molarity of the sucrose inside the cells then there will be no change in weight of the potato disks. I predict this because if the molarities are isotonic inside and outside the cells then there will be a balanced osmotic movement of the water molecules
To investigate the osmotic effect of changing the concentration of sucrose solution; distilled water, 20% sucrose solution, 40% sucrose solution, 60% sucrose solution on the change in mass of potato cylinder after 30 minutes of being in solution.
the same way as it does potato. I would also widen the range of sugar
potato contains. From the graph I am able to see that from 0.0 to 0.3
An Investigation Into the Effect of Sucrose Concentration On Osmosis in Potato Chips My aim is to investigate the amount of osmotic activity between a potato chip and different concentrations of sucrose. The following affect the rate of osmosis: Temperature The warmer most things are the more quickly particles move, therefore increased temperature will increase the rate of osmosis. So, if a potato chip is in a highly concentrated solution the water molecules will quickly leave the chip because of the increase in temperature or if the chip is in a high water concentration the water molecules will go inside the chip. Time The longer you leave the potato chip in the solution, more osmosis will occur, so the greater the change in mass in the potato chip.
there would be no flow of water into or out of the cell so the cell
Finding the Relationship Between Turgidity of Potato Cells and the Concentration of the Surrounding Medium
repeat the process 3 times in total to ensure a fair test. At the end
Investigating the Effect of Different Concentrations of Sucrose Solutions on Potato Tiessue Planning For my GCSE biology coursework, I am going to conduct an investigation into the effect of different concentrations of sucrose solutions on potato tissue. Text Box: A measuring cylinder Apparatus = == == ==
Investigating the Effects of Sucrose Concentration on the Mass of Potato Chips The aim of my experiment is to investigate the effect of varying the concentration of sucrose on a potato chip. I aim to observe the change in mass, and I hope to view what happens to the chips as the concentration increases, and I hope to see the effect that osmosis has on the chip. The experiment that I am conducting uses the process of osmosis. Osmosis is the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration.
6) Leave the tubes for 24 hours. After 24 hours is up, dry the chips
Potatoes, a crop that has become both enjoyable and profitable in the world today and is mass produced and distributed around the world. The uses of potatoes range far and wide in our food they play a vital role most prominently in fast food and various kinds of store-bought snack foods. but their use does not end there, they’ve been used to treat burns in India and studied for their possible help in creating biodegradable packaging goods. The process of their production farming, storing, etc. Their unique distribution, whether it be local or worldwide and, their various ways of consumption; their uses in various unique dishes or their use in creating alcohol.

The Change in O2 Bubbles Produced When Changing the Environment of an Enzyme. Introduction Lab 5 Exploring Enzyme Activity. We are provided a chance to understand how the enzyme catalase can turn a toxic product hydrogen peroxide into a non-toxic product. We will be utilizing a potato in this experiment because it contains the enzyme catalase.
