The process of osmosis is wonderful and intriguing. It is a cellular level process that constantly takes place in the body without even being noticed. This experiment to define how osmosis works in different environments help to understand the process a little easier. In the experiment, its objectives are to define solvent, solute and solution. Define osmosis, isotonic, hypotonic, hypertonic as they relate to relative concentrations of osmotically active substances. Determine the direction and rate of osmosis into and out of simulated cells, explain why diffusion and osmosis are important to cells and how the solutions affect plant cells.

It hosts many processes liking protein synthesis, making of different chemicals using RNA and the most important of all; osmosis. Osmosis is the diffusion of free water across a selectively permeable membrane from a region of higher free water concentration to a region of lower free water concentration. The process was discovered by Henri Dutrochet in France. This process is used to maintain homeostasis to regulate what enters and exits the cell. The job is assigned to plasma membrane, which is selectively and differentially permeable. When describing osmosis, there are three important terms to understand; solvent refers to dissolving agent, solute refers to dissolving substances and solution is the homogenous mixture of two or more kinds of molecules. The process of osmosis is divided into three types of processes based on their mobility of water from each regions. The different solutions are isotonic solution, hypotonic solution and hypertonic solution. In an isotonic solution, the extracellular fluid has the same osmolarity as the cell. If the osmolarity matches, there will be no net movement of water in isotonic solution. In a hypotonic solution, the extracellular fluid has lower osmolarity than the …show more content…
As the data depicts the weight of each bag changed over the time of 40 minutes. The change in weight depicted that the process of osmosis was working with the solutions and the bags. As introduced that osmosis is a process of maintaining homeostasis in the cell to maintain what goes in and comes out. The experiment shows exactly how the osmosis works through the dialysis bag to maintain itself in different environments. The dialysis bags work as a selective permeable membrane for its surroundings. In beaker A, the initial weight of the bag was 11.4 g; but during the process it started losing its weight because it was in a hypertonic environment. Its final weight was 16.5 g. In beaker B, the initial weight of the bag was 11.3 g; it started the in a isotonic solution and remained isotonic because the solution the bag was in had the same solution. Its final weight was 10.4 g. In beaker C, the initial weight of the bag was 8.5 g; the solution it was in was a hypertonic solution and caused the bag to gain water and being a hypotonic solution. Its final weight was 9.5 g. In beaker D, the initial weight of the bag was 9.3 g, and the bag was a hypotonic as a final result. The final weight was 8.9 g. In beaker e, the initial weight of the bag was 10.4 g. The bag was chose as a control for the experiment which included magnesium sulfate solution in the beaker and 1% MgSO4 in the bag. Its final weight was 11.9 g. The final beaker F, the initial weight of the bag was 11 g,

Raisins And Osmosis Experiment

The raisins increased in mass because of the water. The process of osmosis let water molecules pass through the semi-permeable cell membranes in the raisins’ cells. The water level decreased when the process of osmosis occurred and water molecules moved to the hypertonic raisin cells. It is possible that errors could have occurred like measuring the mass incorrectly, putting too much water or too little water in the graduated cylinder, or the amount of time the raisins were in the water could have…

Research Investigation On Osmosis

Diffusion continues until it reaches equilibrium. Osmosis is similar to Diffusion but it’s the process in which water moves across a semi-permeable membrane and goes to the higher concentration of solute.1 2.2. Important factors to Osmosis and Diffusion include Temperature, Concentration and Surface area to volume ratio. Temperature can affect the rate in which a solute dissolves in a solution, higher temperature faster rate of Osmosis. This is caused by the molecules movements being faster…

Osmosis: Concentration Gradient Essay

area of high concentration to an area of lower concentration is commonly known as osmosis. Osmosis is one of the processes that allow materials to move either in or out of an organism or within it. In order for osmosis to occur, there needs to be a semi permeable membrane for the water molecules to pass through. Semi permeability refers to the ability of a membrane to partially allow water to pass through it. Osmosis depends on energy generated by differences in concentration of substances on both…

Lab 1: Diffusion, Osmosis Objective: In this lab we observed osmosis across a semi permeable membrane. Through this experiment, we were able to see the concept of osmosis in action as the water moved from areas of low solute (sucrose) across a membrane areas of higher solute concentration. Another concept we learned in this lab was how tonicity of a solution can affect osmosis into and out of a cell. Materials and Methods: For the first part of this lab, we got a piece of dialysis tubing…

Concentration and Sugar Molecules Essay example

ntroduction: Osmosis is defined as, diffusion, or net movement, of free water molecules from high to low concentration through a semi-permeable membrane. When a substance, such as sugar (which we will be using in the experiment we are about to analyse), dissolves in water, it attracts free water molecules to itself, and in doing so, stops them from moving freely. The effect of this, is that the concentration of (free) water molecules in that environment goes down. There are…
