Examples Of Osmosis In Grapes

297 Words2 Pages
The purpose of the experiment was to test if osmosis worked in grapes, and this was supported by the fact that the grapes did experience osmosis. Over time, they gained mass as water passed through the grapes’ semipermeable membranes. All of the grapes expressed this, often peaking at twelve hours. For example, Grape 5 soaked in Coke reached a total of 9.95 grams at twelve hours. This can also be seen in other grapes, even in other fluids. Grape 2 in water reached its highest mass- 9.84 grams- at twelve hours. There were some grapes that continued to gain mass even after twelve hours, such as the grapes soaked in apple juice, which all peaked at seventy-two hours.
The hypothesis was also clear, as some fluids caused the grapes to grow in mass

We then obsevered the two slides for number of cells as well as for food vacuoles inside a cell using a microscope at times of 0,5,10,20, and 30 minutes. Results The following graphs show the results of this experiment. The tetrahymena sample that was introduced to concentrated tobacco had a lower cell/vacuole ratio than the tetrahymena sample that was not exposed to

This will be done to ensure that the same concentration of sugar and water is present in each and every gummy bear and, thus, will not affect the process of osmosis. Amount of gummy bears: Multiple numbers of gummy bears in a solution might the hinder the transparency of the process that we are trying to examine. The gummy bears might change size and mass in discuss proportion, thus, failing to showcase the entire process of osmosis. To observe the behavior of a singular cell in solutions of varying concentration, we must place one specimen in the solution to observe the effect of osmosis on a holistic

Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.

Chemical stress affected the cell membrane of a beet cell, because of the higher amount of ethanol added to the beet. For example, we added 1% ethanol, 25% ethanol, and 50% ethanol to 3 test tubes with 15 mm of beets inside. We left it with no air inside for 30 minutes then tested the absorbance of the ethanol without the beet. The class got roughly 0.273 for the 1% ethanol, 1.205 for the 25% ethanol, and 1.882 for the 50% ethanol concentration. In each solution, the ethanol was a bit redder than the last.

During the experiment, observations were made of their color, mass, height, and width. This data shows percent mass change of the gummy bear and how the gummy bear was affected by the salt water. It also displays how the height and the width of the gummy bear changed because of the salt water, which made the gummy bear more compact. The more salt that was added to the distilled water, the more compact it was, however, if there was not a lot of salt in the mixture, it became large and fragile. The mass of the gummy bear was increased as a result of less salt being added with the distilled water.

Although osmosis doesn’t just occur in vegetables; however, by using these substances as a test, it can resemble the how osmosis would work in other situations. For example, osmosis is used when preserving fruits and meats. Likewise, this experiment gives a proper demonstration on how to use osmosis to its full potential. This would help

This also shows how much water was transferred from the egg to the sugar solution. The higher the percentage of corn syrup was, the faster the rate of osmosis was. As a result, the egg placed in 75% corn syrup, 25% filtered water had the lightest weight (0.5 oz), while the egg placed in 25% corn syrup, 75% filtered water weighed 2 oz. Overall, the importance of this lab was to understand the process of osmosis and how it differs depending on the type of

Osmosis Lab Report Introduction: The investigation that I took part in this marking period was titled “An Egg-citing Activity”. In this experiment, I further explored the contents and aspects of osmosis. I also looked more closely at the differences and similarities between osmosis and diffusion. The purpose of the investigation was to examine a raw egg, classified as a large cell, after it had been placed in vinegar for two days and then put in different liquids. To put this into real life terms, the question that was used for this experiment was, how do drinks that we consume affect the cells in our body?

For this lab I will be using water and sucrose to demonstrate the rate of osmosis. In this lab I will be exploring how temperature impacts the rate of osmosis by placing pieces of potato of equal size in solutions of different temperatures and observing the change in mass of potato after a given period of time. The change in mass will indicate the rate of osmosis.

Osmosis Lab Report Research Question: How does the change in the concentration of a sucrose solution affect the process of osmosis in a potato cell by measuring its mass? Background information: 1 Osmosis is the process by which a liquid passes through a semi-permeable membrane, moving from an area with a high concentration of water to a low concentration of water. There are various factors that affect osmosis such as: concentration, surface area and temperature. The concentration of solutions can affect the rate of osmosis, as there is more difference in the concentration of the solutions, which means osmosis, will take place quicker. Surface area could affect osmosis based on the ease by which molecules can get through the semi-permeable

Orange juice is also the most consumed fruit juice worldwide, mainly because of its nutritious benefits, particularly high Vitamin C levels. It has a great deal of history and has been used for a number of purposes dating back to the Age of Discovery. One of these purposes is being used in medical and science experiments. It is featured in the following experiment, which focuses on the relationship between an orange’s size and its percentage of water. Key questions that will be answered in the experiment include: What is an orange?

 Two of the same types of plants were used, in order for the results to be reliable.  One of the plants was labelled DISTILLED whereas the other was ACIDIC, so the results don’t get mixed.  The DISTILLED plant was used as a controlled variable, where normal spring water was used (pH 7.3)  The ACIDIC plant was the one the experiment had taken place on, this was where lemon water was used (pH 2.0)  Throughout the experiment pictures were taken, so one will be able to notice the colour change on the acidic plants, as it had started to slowly die. With both plants you are able to notice that they had both started to grow flowers, but more the spring watered plant than that on the lemon juice watered one.  The results of the plant growth was recorded to we would be able to notice the amount it had grown, this would be the water compared to lemon juice.

Biology Design Practical Joshua Edwards What are effects of the volume of a potato and the amount of weight it loses when placed in salt solution? Introduction This design practical uses a potato’s surface area to volume ratio to see what affects it has on osmosis in different concentrations. Osmosis is the movement of water molecules through a cell membrane into an area of a higher solute concentration. The movement goes the way of the solvent with more solute because the lower solute concentration is drifting through balancing the ratio of solute per solvent (En.wikipedia.org, 2018).
