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.
Investigation of the Concentration and the Effect of Sucrose on Osmosis in Apple and Potato Tissues
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
Conclusion In my conclusion, the potatoes with the lowest concentration gained the most mass, and would become hard relating back to the Turgor theory I stated earlier. In contrast to this, the potatoes in the most concentrated solution lost the most weight thus becoming plasmolysed and limp also relating back to the background I have mentioned earlier. Evaluation In general the experiment was succesful the results were consistent and also were in accordance with the theories made at the start.. The experiment could have been improved by: · More subjects used instead of potatoes · More potatoes · Wider time ranger · Different molarities Using this variety of methods could have improved the experiemnt, however I was generally satisfied with the results of this osmosis experiement.
The potato tubes in higher concentration sugar solution will shrink
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.
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.
Finding the Relationship Between Turgidity of Potato Cells and the Concentration of the Surrounding Medium
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.
there would be no flow of water into or out of the cell so the cell
6) Leave the tubes for 24 hours. After 24 hours is up, dry the chips
with 0.0M (distilled water) and go up by 0.1M until I reach 1.0M and I
