  • Experiment: Exploring Changes In Osmosis

    Exploring changes in Osmosis Abstract: In science, it’s said that cell tissue can be permeable, this means that the cell tissue can regulate what fluids or airs travel through the membrane. For a cell to be able to have that kind of attribute, it permits us to conclude that cell tissues contribute significantly in passive transport. Passive transport is the measure of constituents through the cell membrane minus any involvement of energy by the cell. This experiment was done in order to govern how osmosis occurs in two different substances. I placed a blotted deshelled egg in beaker A in 14% distilled water allowing it to sit for 10 minutes, 20 minutes and 30 minutes. I also placed another blotted deshelled egg in beaker B in 30% sucrose allowing it to sit 10 minutes, 20 minutes, and 30 minutes as well. Osmosis visibly happened because there was a change in mass in both of the eggs. The outcomes showed us that diffusion transpired differently for beaker A and for beaker B. For beaker A, the egg gained mass causing the egg to weigh more than it initially weighed before osmosis. For beaker B, the egg loss mass causing the egg to weigh less than it initially weighed before osmosis. Both eggs visibly went through change. One causing an egg to gain. My hypothesis was accepted because my results turned out to be accurate. I roused my procedure and was able to appropriately form a sensible conclusion. I used the characteristics of osmosis and it allotted me great results.…

  • Egg Placed In Syrup Lab Hypothesis

    When the egg was placed into syrup, a hypertonic solution, it shrunk in size. This result supports my hypothesis. The mass of the egg before it was placed in syrup and after it was placed in syrup changed drastically. There was a 16 g decrease in mass that happened to the egg during its time in the syrup. Both the long and short circumference of the egg decreased. The long circumference before the egg was placed in syrup was 18.75 cm and after it was taken out of the syrup the long circumference…

  • Egg Storage Condition

    3.0 RESULTS AND DISCUSSION 3.1: Effect of Storage Conditions on Egg Weight Tables 1- 2 show the results of effect of storage conditions on eggs weight (chicken eggs and quail eggs). The weight of chicken eggs stored at ambient condition (control), moist sawdust, refrigerator and those that were dipped in oil reduced from 63.61-60.03g, 63.11-60.99g, 61.12-59.41g and 66.12-65.79g respectively. While the weight of quail eggs stored at ambient condition (control), moist sawdust, refrigerator and…

  • Osmosis And Diffusion Lab Report

    of the dialysis bag because its molecules are larger than the pores of the bag. Also, I2Kl will diffuse into the bag making the solution inside the dialysis bag purple in color. Furthermore, the purpose of experiment B of exercise 2 is to be able to identify the effects of a hypertonic, hypotonic, or isotonic solution cells. For instance, when a cell is placed in a hypertonic solution, the water moves out of the cell causing the cell to undergo plasmolysis. Plasmolysis is the shrinking of the…

  • Atsuete Beets Experiment

    As seen in the (Fig. 3) it showed that water placed in the cells were filled with violet colored sap inside the cell (wet mount) It was turgid. This is because of water abundance in and out of the cell. After removing the water and replacing it with the 5% salt solution, the protoplasm shrunk away from its cell wall because the water molecules in the cell moved to a higher concentration (outside the cell). As seen in (fig. 4) it showed that half of the cell is empty because plasmolysis occurred…

  • Osmosis Lab Report

    vacuole was filled with a water solution. Next, students added a drop of 10% NaCl solution on a slide, then again examined the slide and figure out that vacuole of cell got shrunk, because the total solute concentration of the vacuole decreased when 10% NaCl solution was added. The plasma membrane and chloroplast also got shrunk. After that, by cleaning the slide and adding a drop of distilled or deionized water, the cells regained their original appearance and students saw that the space…

  • Blood Cell And Osmosis Experiment

    solution has less concentration than the amount in the beaker than it will decease it weight. So I predict that for the Bag A that it will weigh less over a period of time because of osmosis. The other bags that has a percentage more than the beaker will increase. If they have the same amount then it will remain the same. For Procedure 9.7 If the Sheep blood cell water flow is effected by the solution that is added then the structure will either shrink or burst in it unknown surrounding. The…

  • Potato Osmosis In Potato

    of the sucrose solution gets higher, it gets closer to the water potential of some of the cells. Therefore, as the cells all have different water potentials, some of the cells may have a higher water potential than the sucrose solution and some water molecules may move out of the cell, resulting in a loss in mass for some cells. This would cause the overall change in mass to be lower as some cells lost mass but most of the cells gained mass. From my graph I can see that the best fit line…

  • Diffusion Across Plasma Membrane Lab Report

    inside of the bag. The experiment showed that the amylase broke down the starch into glucose and the glucose was then able to penetrate the membrane. This was shown by the glucose test. If the glucose molecules were not able to cross the membrane of the dialysis tubing, the glucose test would not be able to detect any glucose in the fluid surrounding the tubing. The glucose test read “1000” for the solution on the outside of the membrane. In the inside of the tubing, the glucose test read “500”.…

  • Spinach Photosynthesis Lab Report

    be calculated. Initially, the chloroplasts needed to be extracted from the spinach leaves. The stems from the spinach leaves were removed because they are more rigid. The spinach leaves were then placed under a lamp to allow for the absorption of light where they were “woken up” for photosynthesis. The spinach leaves were placed in a chilled blender with a sucrose solution and blended in short three 10-second increments. The blender was chilled to keep the solution cold to avoid the…
