Sucrose solutions

I was able to determine which solution corresponded to which molarity by my knowledge of how water osmosis from high concentrations of water to low concentrations of water. I determined solution D to be the lowest molarity of 0.0 moles because the potatoes that were immersed in this solution had the highest average percent increase in mass of 23.08%. Since there is a small amount of sugar in the potato cores and the potato cores gained a large amount of mass, that must mean that there was a higher

different sucrose solutions overnight. The hypothesis was if you place Jicama cores into different cups containing a lower amount of sucrose concentration and a higher amount of water concentration, then the cell’s mass would change. It was predicted that the cells’ mass would decrease due to less water transferring through the plasma membrane, and this is due to a lower water concentration being inside the solution than inside the core. Tests were taken to see which sucrose solutions caused the

of Osmosis with Potato Cells in Sucrose Solution Introduction: Small slices of potato are placed in six concentrations of sucrose: 0.0 M, 0.1 M, 0.2 M, 0.3 M, 0.4 M, and 0.5 M. The initial mass of potato is noted before being placed in the solution. The potato remained in the solution for one hour then the potato was removed from the solution and dried off before the final mass was noted. The null hypothesis is that the solutions of different molarities of sucrose will not affect the

identify the internal concentration of potato cells when soaked in solutions with different sucrose concentrations. During this experiment, potato tuber segments were soaked in solutions containing 0 M, 0.1 M, 0.2 M, 0.3 M, 0.4 M, and 0.5 M of sucrose for one hour. After the allotted time, the potato segments that were soaked in the 0.5 M solution (the highest concentration) decreased in mass, and the segments soaked in the 0 M solution (the lowest concentration) increased in mass. Therefore, the alternative

dish Each solution was made with the same volume of liquid (50 mL) Each petri dish contained 5 Lincoln Peas The size of the Peas where had been all relatively the same size Each petri dish had contained 5 pieces of paper towel All seeds were exposed to the same amount of temperature and light as they were all kept in the same location at the same times The water of all conditions were sourced from the same distilled water throughout the experiment Same type of sucrose in each solution Same size

One experiment was conducted for this lab report on osmosis and diffusion and how the concentrations effect a cell. The lab consisted of weighing 4 potato cylinders and putting them into 4 cups with different levels of sucrose solution. After incubating for two hours the potatoes were weighed again and the data was collected. The results showed two increasing, one staying the same, and one decreasing in mass. Osmosis is when water moves across cell membranes until both sides are balanced (Campbell

Choudhury Asif Ibne Yusuf Lab Section 1 Using different concentrations of sucrose affecting movement of water in and out of dialysis tube to find the concentration of an unknown solution Introduction This experiments attempts to find how different concentrations of sucrose affect the amount of osmosis that occurs in a dialysis tubing and finally to find concentration of the unknown sucrose solution. The dialysis tubing represents a cell with a semi permeable membrane therefore water with along with

states that the size of a particle will not change the water potential or occurrence of osmosis in a solution-submerged cell, only the amount of the solute in the solution will affect osmosis. To test this, we used three different sized solutes—sucrose, glucose, and NaCl—to see if the size of the solute had an effect on the osmosis of water into or out of white potato cells that were submerged in solutions containing the 3 solutes. We found that the size of the particles of solute does not affect osmosis

Abstract. The purpose of this lab was so we could see how water potential works. We also saw how water requires certain characteristics to be able to be taken up by plant tissue. The results suggest that a higher sucrose concentration in the water results in a lower weight of the potato tissue. This is important because plants need to be able to take up the water that is provided to them. If the water does not have the right characteristics, the plant cannot get nutrients as it needs to, and it cannot

hypothesis I previously had was that if the sucrose concentration increases, then the rate of water movement increases. I have chosen to accept this hypothesis because my data proves it to be true. Based on my data, as the sucrose concentration is lower, the average change in mass is less than when the sucrose concentration is higher. This is because more water has to travel in or out of the dialysis bag in order to help dilute the high concentration of the solution in the beaker down to even it out with
