A lot goes on throughout our body that we don’t know about; many of it is necessary for our survival. One thing that is vital to our existence that happens without our even knowing is osmosis. According to “HyperPhysics” by Georgia State University, osmosis helps bring essential minerals that we need to our body. Without it, we would not get these essential nutrients.
Osmosis is the diffusion of water. The Society of Oxford University Engineers (SOUE) states that osmosis is “the net movement of water from a weaker, less concentrated solution across a selectively permeable membrane, with rejection of solute molecules or ions, to a stronger, more concentrated solution on the other side.” This means that water can move as a weaker concentration through a permeable membrane to the other solution on the other side of the membrane. The smaller the ion channel, the less and smaller particles will come through. If there was a larger ion channel, than more and larger particles would be able to move through the membrane. …show more content…
That’s why in this lab we took iodine and starch solutions to see how osmosis would affect these two solutions. One reason we picked these two solutions is because when they come in contact with each other, the mixture turns a dark blue color. So if osmosis works properly, then all of the mixtures will be blue. For example, in one of our beakers, we put an iodine solution in a dialysis tube and submerged it in a starch solution. If our hypothesis is correct, then at the end of 2 days, the starch solution and iodine solution would have turned a dark blue color from having a chemical reaction with each other. The way the chemicals are able to interact with each other is through osmosis. The two solutions go through osmosis to be able to mix with each other. They both go through the permeable membrane and that is when you see the chemical

Lab Report On Osmosis

Osmosis Lab Mikayla Clarke 10/2/16 Abstract: The purpose for the osmosis lab was to observe osmosis and determine the sucrose molarity of a potato and a carrot. This lab was separated into two different parts. In the first part of the lab, osmosis was observed by placing dialysis bags with various concentrations of sucrose into beakers of water. In the second part of the lab, the molar concentration of a potato and a carrot were determined by placing slices of potatoes and carrots…

Osmosis Lab Report

purpose of this lab was to explore concentration gradient, diffusion, and osmosis further. Egg one’s circumference ( the long way and short way) and its mass will be compared to egg two’s circumference and its mass. In this lab we look at concentration gradient and osmosis. Concentration gradient is the difference in concentration from one place of high concentration to an area of low concentration. In an egg, there is protein, carbohydrates (sugars), and water. We are also studying osmosis. This is diffusion…

Egg Osmosis Lab Report

This lab project was to demonstrate the system of how osmosis and diffusion works. More specifically to examine the movement of how substances flow in and out of the cell membrane. Which was demonstrated by soaking an egg in various liquids with a time table to see how it would affect the egg. The egg can be substituted as the cell membrane. Predictions, observations, and procedures were made. Before the lab procedures can be discussed, Osmosis and other key terms should be mentioned and explained…

Potato Osmosis Lab Report

Osmosis in Potato inquiry Introduction Cell membranes are permeable to water and all cell membranes are selectively permeable. This means some substances are allowed to enter the interior of the cell and some substances are not allowed to enter the interior of the cell. Osmosis is the movement of water across membranes to balance solute. Osmosis moves water from a hypotonic area to a hypertonic area, also known as diffusion. This process is especially important in a plant cell because it allows…

an animal cell and also see the effects of the different solutions that are used on the egg during the experiment. Also made a hypothesis on what will happen to cell when it is placed in water by saying it is going to cause the cell to experience osmosis and the altering of the shape of its cell membrane. This was proven wrong because the egg did not alter in shape, all it did was stay the same shape but increase in mass. The answer that was conducted from this experiment was used on a shell-less…

Osmosis Potato Lab Report Biology 4u Essay

Introduction The movement of water molecules across a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent, each containing different concentration levels, then the water would move along its concentration gradient until each side of the membrane are equal. The water moves because the membrane is impermeable to the solute and the solute concentrations may differ on either side of the membrane. Water molecules may move in and out of the cell, but there is no net diffusion…
