Conclusion And Evaluation Of Osmosis Potato Lab - 889 Words

Saam Baharmand Period 5 11 October 2014 Conclusion and Evaluation of Osmosis Potato Lab Hypothesis: I believe that the O Molar (M) solution of sugar and distilled water will be isotonic because there is no sugar in the solution. This Hypothesis was not supported by the results of the lab. 1) The line graph of the data collected shows the least amount of change in mass (1.8%) in the potato soaked in the 0.2M sugar solution. This means that the potatoes soaked in the 0.2M solution were the most isotonic of all the potatoes. 2) The beginning mass of the potato soaked in 0.2M solution was 10.6g and the ending mass was 10.8g. This data collection proves that there was no significant loss or gain of mass in the potato (soaked in 0.2M sol.) thus making it isotonic. 3) The percent (%) change in mass of the potato in the 0.0M sugar solution was recorded on the graph at 31.8%. This means that there was a significant increase in mass of the potato thus making the solution hypertonic and the potato cells hypotonic. Variables Independent: 5 interval sugar solutions of 0.0M, 0.2M, 0.4M, 0.6M, and 0.8M (mixed with distilled water) Dependent: % Mass Change of potato after 24 hours in solution Quantitative Relationship: When the intervals of sugar solution change, the % mass of the potato changes as a result. The 0.2M solution proved to the most isotonic while the 0.0M and 0.6M potatos proved to be the most hypotonic and hypetonic respectively. The potato of the 0.2M sol.Show MoreRelatedPotato Cubes Mass Lab Report1117 Words   |  5 Pages 2. Research Question: How 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 diffusionRead MoreEffect of Different Concentrations of Salt on Potato Cell Mass1461 Words   |  6 Pages Aim To investigate the effects of increasing salinity on potato cell mass. Background Information This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a cell wall, which lets smaller molecules such as water through but does not allow bigger molecules to pass through. This processRead MoreMicroscopy, Cell Structure And Function1208 Words   |  5 Pagescell structure and function TASK 3 Write a scientific report on osmosis experiment showing the: Aim, Introduction, and Hypothesis.

To do this I will conduct an experiment. Introduction To carry out my experiment, I will place the potato tubes into a solution containing part sucrose and part water. The potato tubes will all be cut out of the potato using a cork borer and will all be cut to the length of 25mm. This will remainRead More Investigate the Osmosis of Potato Cells in Various Salt Solutions2525 Words   |  11 PagesInvestigate the Osmosis of Potato Cells in Various Salt Solutions Introduction I have been asked to investigate the effect of changing the concentration of a solution on the movement of water into and out of potato cells. I will be able to change the input of my experiment. The input variable will be the concentration of the solution. The 100% solution is sodium chloride dissolved in water (salt water). This will be referred to as the 100% solution from now on. But the type of solution is notRead MoreOsmosis Internal Assessment - Biology Higher Level3984 Words   |  16 Pages| The effect of salinity on osmosis of solanum tuberosum L.(potatoes) | Biology HL Internal Assessment – Year 10 | | Teresa Nguyen | | Table of Contents 1 DESIGN 2 1.1 Defining the problem 2 FOCUS QUESTION 2 HYPOTHESIS 2 BACKGROUND INFORMATION 2 INVESTIGATION VARIABLES 3 1.2 Controlling Variables 3 TREATMENT OF THE CONTROLLED VARIABLES 3 CONTROL EXPERIMENT 4 1.3 Experimental Method 4 MATERIALS 4 RISK ASSESSMENT 5 METHOD 5 2 DATA COLLECTION and PROCESSING 7 2.1 Recording RawRead MoreOsmosis in Different Concentrations2449 Words   |  10 PagesI am going to investigate osmosis when potato is placed in different   concentrations of sucrose.

The diffusion of free water across a selectively permeable membrane, whether artificial or cellular, is called osmosis. The movement of water across cell membranes and the balance of water between the cell and its environment are crucial to organisms. (Diffusion And Osmosis - Difference And Comparison | Diffen). A semi-permeable membrane known as the cell membrane surrounds the living cells of both plants and animals. Both solute concentrationRead More The effect of osmosis in potato cells with different concentrations of sucrose solution1887 Words   |  8 PagesThe effect of osmosis in potato cells with different concentrations of sucrose solution Aim: To test the effect of different concentrations of sucrose solution to osmosis in a potato cells by putting potato pieces in test tubes of water containing different concentrations of sucrose solution. Scientific Theory: Osmosis is defined as the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration
