A way to relate this to the real world is that people could use the concept of osmosis to make more accurate administering IVs to put into patients in hospitals. Osmosis is extraordinarily important in the biological processes where the solvent is water. This transport of water and molecules across the membranes is essential to many processes in living organisms and keeping them healthy. In general, this experiment helped understand the different ways osmosis works and how concentration can change the weight of…
Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions.…
A fresh potato is peeled, weighed, and soaked in a strong salt solution. The next day, it is discovered that the potato has lost weight ------…
Basically any water that entered the egg is considered osmosis. The type of transport was…
People who live close to Ballona creek are accusing Industries for the contamination of the water. The thing that they would never think of was that it was the asphalt pit. When there is heavy rain, the asphalt pit would over flow and then it runs down into the sewer system, leaking into the creek and draining into the ocean. The Page Museum and Natural History Museum of Los Angeles County have paid local water controllers $15,000 dollars for discharging contaminated water into the storm drains in 2006. And in 2002, the Page Museum paid $3,000 to a coastal cleaning project to resolve a storm water release violation. This source is credible because it was written by Jasson Song and Tony Barboza. Their arguments are solid and clear. They cover…
Cell Transport Lab Hypothesis: I hypothesis that there will be a movement of molecules out of the egg, and will move into the water solution. Osmosis will occur...…
The lab for this paper was conducted for the topic of osmosis, the movement of water from high to low concentration. Five artificial cells were created, each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic, hypotonic, or isotonic solutions for a period of 90 min. Over time, the rate of osmosis was measured by calculating the weight of each artificial cell on given intervals (every 10 minutes). The resulting weights were recorded and the data was graphed. We then could draw conclusions on the lab.…
This experiment demonstrates the process of osmosis because when the egg is placed in the water, it gets slightly larger due to the different…
An aqueous sodium chloride solution was prepared by adding solid sodium chloride to 1500 mL of distilled water while stirring until an uncooked egg floated. The amount of salt added had an unknown mass; however the density was determined indirectly by the use of four different techniques: burette, Mohr pipette, volumetric pipette, and a volumetric flask.…
The effects osmosis has on a cell are either that it becomes turgid and hard as water enters the cell or it becomes dehydrated (this is called plasmolysing in plant cells) as water leaves the cell and the solution enters. There is a change of mass, volume, texture and length.…
The purpose of this lab is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic, isotonic, and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell, it keeps the cell the same it’s just in a different environment.…
What is osmosis? Osmosis is a very important part of biology. It is the spontaneous passage of water or other solvents through a semipermeable membrane. A semipermeable membrane is one that blocks the passage of dissolved substances. Osmosis occurs when there is an imbalance of solutes outside of a cell versus inside the cell. A solution that has a higher concentration of solutes than another solution is said to be hypertonic, and water molecules tend to diffuse into a hypertonic solution. Cells in a hypertonic solution will shrivel as water leaves the cell via osmosis. If a solution has a lower concentration of solutes than another solution it is said to be hypotonic, and water molecules tend to diffuse out of a hypotonic solution. Cells in a hypotonic solution will take on too much water and swell. The purpose of this experiment is to observe the process of osmosis and getting a better understanding on how osmosis works. To study osmosis I will be using two non-boiled eggs. Eggs are used because under the hard outer shell is a semipermeable membrane that allows air and moisture to pass through. Because water molecules can move into and out of the egg but large molecules cannot, the semipermeable egg membrane allows for an exploration of the concepts of diffusion and osmosis. I will be removing the outer shells of the eggs and then testing one of the eggs with water and the other egg with corn syrup to determine which solution is hypertonic and which solution is hypotonic. My hypothesis is, is that the egg in the corn syrup solution will be hypertonic where the molecules will move out of the egg causing it to shrivel and the egg in the water solution will be hypotonic causing the egg to swell.…
There is a lot of water on the Earth’s surface, most of the water on Earth is in oceans. Yes. water is also located in other places like rivers, lakes, streams, and even ponds. So i will be testing how salty dose the ocean have to be to make an egg float.…
{Online, Biology. “Osmosis.” Osmosis, Biology Online, 25 Dec. 2016, 2:27, www.biology-online.org/dictionary/Osmosis.} This means that water will flow through the naked egg’s outer membrane from the outside to the inside. This is because inside the egg has a lower concentration of water than outside the egg. Since osmosis is based around mainly water and substances with extremely low acidity, we decided to use plain water as our control, and add the food coloring to the cups already filled with…
