Egg Osmosis Egg Lab Report
Based on the data and the recorded observations, my hypothesis is correct. When a solution is hypotonic, this causes the cell to swell, because there are more water molecules on the inside of the cell. If positive feedback continues, the cell will eventually burst. When a solution is hypertonic, this causes the cell to shrink, because there are more water molecules on the outside of the cell. Over time, the cell will start to function poorly (“Difference between Hypertonic, Hypotonic, Isotonic Solutions”). Therefore, the cell needs to maintain its internal environment through osmosis. In a hypotonic solution, osmosis allows water molecules to move from the inside of the cell to the outside, so as to keep the concentrations balanced. In a hypertonic …show more content…
Corn syrup has a very high density due to the high concentration of sugar molecules. Because the sugar molecules is too large, it cannot pass through the semipermeable membrane of the egg. As a result, only the water molecules from the egg can move to the outside. These water molecules pass through the membrane of the egg into the corn syrup until the concentration of water molecules is balanced on both sides. This is evident from the data, which states that the weight of the egg decreased from 3 to 0.5 ounces. Also, the pictures above show how the egg changed from being tight and solid to being flexible. The observations also say that the egg felt like a water balloon and was full of water inside. Overall, the egg greatly shrunk in size. Finally, when the egg was placed in corn syrup, it floated on the surface of the solution. This was because the egg floated in solutions hypertonic to its inside. 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
Gummy Bear Lab
219 Words | 1 PagesI predicted this because the water is hypotonic to the gummy bear, so the water would diffuse into the gummy bear causing the cells to swell and increase in size. The control group in this experiment was gummy bears that were not soaked in water because
AP Biology Chapter Summary
1515 Words | 7 PagesIn walled cells, turgor pressure, the resistance to water movement by the cell wall, also affects osmosis. When cells are placed in a hypertonic solution, one with a higher solute concentration and lower water potential, water will move from the cell to the solution, causing the cell to be flaccid, or limp. As water diffuses out of a cell, it undergoes plasmolysis, in which the cell’s living part, including the plasma membrane shrinks and pulls away from the cell wall. On the contrary, when cells are placed in a hypotonic solution, one with a lower solute concentration and higher water potential,
Beta Vulgaris Lab Report
1572 Words | 7 PagesThe membrane permeability of Beta vulgaris is affected by ethanol solution Introduction Cell membranes are the semi-permeable membrane that surrounds all cells. It separates the extracellular environment from the intercellular environment. It is a phospholipid bilayer which contains various proteins, lipids and carbohydrates all serving different purposes. It is this structure which allows for the transport of nutrients, proteins and water. (Nature.com, 2014).
Gummy Bear Osmosis Lab Report
1485 Words | 6 PagesThe cell membrane is semi-permeable, meaning some substances can pass through but others cannot. Osmosis is the diffusion of solvent molecules (e.g. water) across the membrane from an area of high concentration to an area of low concentration (Lopez & Hall, 2022). When the fluid on the extracellular side of the cell has a higher concentration than the cytosolic side it is hypertonic. When it is lower than the cytosolic side it is hypotonic. When both sides of the membrane have equal concentrations, they are isotonic.
Rhubarb Osmosis Lab Report
1127 Words | 5 PagesAdditionally, 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.
Essay On The Effect Of Temperature On Osmosis
1159 Words | 5 PagesFor 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.
Gummy Bear Lab Report
1183 Words | 5 PagesThe purpose of this experiment was to observe the relationship between different solutions and their effect on the mass and length of a gummy bear. Gummy bears with the same relative size and colour were placed in 50 mL beakers with the same amount of their designated liquid. The different solutions studied were water, oil, vinegar, a simple sugar solution, and rubbing alcohol. In the end, based on the observations made, the majority of the hypotheses created were not proven to be correct.
Egg Drop Lab Report
550 Words | 3 PagesIn this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
Lab Report: Diffusion And Osmosis
1274 Words | 6 PagesOsmosis is the diffusion of water through a membrane from an area of high contraction to an area of low concentration. Osmosis happens in three different environments. Osmosis is like diffusion in it requiring no energy. Osmosis can happen in three different types of environments; Hypertonic, Isotonic and Hypotonic. If osmosis were to
Diffusion And Osmosis Lab Report
819 Words | 4 PagesThe cell membrane regulates the deoxyribonucleic acid, enzymes, and it builds a pathways for any reaction such as metabolic. When waste products are present the cell membrane gets rid of it and the cell membrane allows important things inside . A great example of what the cell membrane allows in or out is water and oxygen. Specific molecules are only made to enter the cell which is also called semipermeable. Molecules can be passed by active transport or either passive transport.
Osmosis In A Potato Cell
1598 Words | 7 PagesOsmosis 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
Egg In Vinegar Lab Report
738 Words | 3 PagesThink of it like this, adding salt to the water makes it like an ocean which is easier to float and swim in than just normal/ distilled water. This is because salt makes water denser. When salt water gets denser, the easier it would be for objects to float on it. My hypothesis was correct. The water did go inside the egg, but the ones with least salt increased the most, unless the egg was the smallest and it had enough space to take in a lot of extra water.
Osmosis Experiment Essay
1605 Words | 7 PagesThe hypothesis we came up with for this project was that in the distilled water there wouldn't be no change in the potato, we wouldn’t see a gain or loss with the water sitting in the beaker. The beaker with the 30% Sucrose and Distilled water we predicted that there was going to be weight gain to the potato. And for the distilled water with the 30% sucrose and we predicted weight loss. But the results came out to be the first bag content being isotonic the second bag came out to be hypotonic and lastly the result came out to be
Potato Osmosis Lab Report
1078 Words | 5 PagesBiology 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).
Lab Experiment: Osmosis Visking Tube Lab
830 Words | 4 PagesThis experiment is to investigate the relationship between solute concentration and the movement of water through semipermeable membrane by the process of osmosis. The purpose of this The Visking tubing apparatus establishes the osmosis procedure. The Visking tubing is a semipermeable membrane filled up with concentrated sucrose solution. The surface of the semipermeable membrane symbolizes the visking tubes and the mixture demonstrates the cytoplasm. If the Visking tube is absorbed in water, after a period of time, it will be have water inside water, this is because the water molecules can pass through the tubing, while the larger sugar molecules cannot diffuse out from the tubing because the size of sugar molecules do not allow it to go through the tubing.
