There are total three variables in this hypothesis.
First, the test solution could be either hypertonic or hypotonic. The DI water could be the most hypertonic thing in this lab. However, other big molecule like sugar could be hypotonic. In this case, we can deep the de-shelled eggs seperatly into these solutions. After a long time, we can check the changing of weight to determine how different solutions influence the diffusion, or there will be no diffusion happens in some solutions. Also, in another section, we will use a dialysis bag to deep in a mixed solution. After a while, we are able to check both solutions inside outside of the bag to determine which of these molecules are able to transpass the dialysis. In the third section, we can use the young elodea leaf to deep in the DI water. In this case, if the diffusion happens which suppose to under our hypothesis, we can easily find it out the cell membranes seperat from the cell wall. …show more content…
In the first section, it will be very easily to find out by measure the weight of eggs. In this case, we need to make eggs deep in several different solutions. Some of them should have higher concentration than the solution inside the egg, and some of them should not. By comparing to each others, we can determine the volume of water changes inside the egg, in order to proof our hypothesis. In the second section, the solution inside of dialysis bag which pertend as human’s blood should have higher concentration than the solution it dept into. By comparing weights before and after the process, we can find it is either gaining water or losing water. Same for the third section, if the cell membranes of elodea leaf seperat from cell walls, we can say it was losing water inside the cell. At the same time, as the solution inside the young elodea leaf’s cells has much higher concentration than the net water, it could also be one of proofs for our

the aim and background information 2.1. Diffusion is the spontaneous kinetic movement by which molecules move from an area of a high concentration to an area of low concentration. 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…

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…

Osmosis: Carbon Dioxide and Cell Membrane Essay

passive transport comes entirely from kinetic energy that the molecules have. The simplest type of passive transport is diffusion, which is the movement of molecules from an area of high concentration to an area of lower concentration. Diffusion moves down the concentration gradient, which is the difference in the concentration of molecules across a space. Osmosis is a type of diffusion in which water molecules move down the concentration gradient. When the concentration of solute molecules outside…

Essay on Osmosis and Tape Measure

Aim: The aim of this experiment is to observe the way the eggs that model cells absorb different liquid concentrations. Hypothesis: The egg will become bigger or smaller in weight and circumference as well as change in color because of the liquid it is in. Equipment: • Vinegar • Salt 50 ml water 250 ml • Food coloring • Coke • Lemonade • Water (control) • Cups (18) • Triple Balance Beam • Tape measure • Paper • Pencil • Gloves (optional) • Graduated…

Egg Lab

Egg Lab Report The egg lab taught about diffusion, osmosis, and the different types of solutions, hypertonic, hypotonic, and isotonic. In our lab, we used an egg, a cup, a string, a rubber band, a ruler, a graduated cylinder (100 ml), saran wrap, vinegar, a soap solution, a salt solution, and a corn syrup solution. We measured our egg by wrapping the string around it. Our egg was 13.5 cm. During testing, we found our hypotheses were not always right. Day one of testing, we used vinegar. We thought…

Testing for Diffusion: A Guided Activity Summary of experiment: The point of the experiment was to see how diffusion works and what it effects. The experiment is tested to see if the solution would be either starch or glucose. Answers of analysis questions: -The starch remains in the dialysis bag because the molecules are bigger than the pores. Also because there is no blue on the outside of the tape. - - record the data every 5 minutes or so to get more data and you can see the diffusion progress…

Essay on Osmosis and s. Cerevisiae

from a lower solute concentration to a higher solute concentration. It is important to understand the concept of osmosis when studying cellular membranes. The cell controls the movement of molecules in and out using osmosis and other types of diffusion. The cells use the techniques depending on the environment they are surrounded. These environments can be categorized into isotonic, hypertonic, and hypotonic. Most organisms need an isotonic or slightly hypotonic environment for survival; however…

side where it binds. Hormones are transported in the blood whereas local chemical mediators are spread directly by diffusion, hormones have a widespread effect, affect different organs and affect different parts of the body e.g. distant organs and only affect cells with the right receptor. There is a thick cuticle on the upper surface of plant leaves so there is a shorter diffusion pathway on the lower surface. Hydrolysis and condensation are important in the formation of new adult proteins as…

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 of water. Because of concentration…
