Carrot Osmosis Lab Report
Lab Report
INTRODUCTION: This experiment is being done to find out what happens to a carrot or a potato if you place them in two different solutions. Osmosis has a lot to do with this experiment and is the movement of water molecules from a higher concentration to a lower concentration. Osmosis only deals with water and is a type of diffusion. The difference between all three solutions is that in a hypertonic solution the cells fluid rushes out of the cell and causes it to shrivel. In a hypotonic solution water rushes into the cell and causes the cell to expand and eventually pop. In a isotonic solution water rushes in and out of the cell and causes the cell to stay the same.
HYPOTHESIS: On the carrot lab the carrot that will be placed in the salt water will be hypertonic and will shrink because the cells will shrivel. The carrot that is placed in just water will be hypotonic and will expand or get bigger.

Underneath each beaker we had a paper towel that we had to label hypotonic and hypertonic. One member from each group had to bring either a potato or a carrot, cut it in a cube with a scalpel, and then measured the length, width, and height of the cube with a ruler. Once all of that was done the cubes were placed in the solutions.

    Diffusion and Osmosis are two concepts that go hand in hand with each other. Diffusion is simply described as the movement of a substance from a region of high concentration to a region of low concentration. In another words, the substance will move down its concentration gradient which is “the region along which the density of a chemical substance increases or decreases” (Campbell Biology pg. 132). If you understand the concept of diffusion then osmosis is a very simple process. It can be defined as the diffusion of water across a permeable membrane. Osmosis can be cellular or artificial, so even though we are creating artificial cells in this lab, it is still considered to be osmosis. During osmosis, a solvent is trying to get through a selectively permeable membrane to make the concentration of that solvent the same on both sides of the membrane. The rate of osmosis depends on the type of environment the cell is in. There are three different environments that a cell can find itself in, a hypertonic environment, a hypotonic environment, or an isotonic environment. The environment a cell is in will determine its tonicity which is “the ability of a surrounding solution to cause a cell to gain or lose…

    The purpose of this experiment is to observe the osmosis reaction in a potato with salt and water. In cooking cooks will soak their cut potato's in water if they will not use them immediately. This allows the potato's to be used later without turning color. The experiment shows the flow of water through the membranes of the potato with salt over a period of four hours.…

    As the concentration of a solute in water will, through osmosis, transfer until the concentration is nearly the same both inside the cell, or in this case potato, and outside of the cell, the potato strips both gained and lost mass due to the different concentrations of sugar in water. As expected, the potato strips placed in the concentration of sugar water closest to the concentration of sugar water in a potato had the least amount of change in mass. As the potato strips placed in substance Z and substance A both changed 7%, the concentration of sugar water in a potato must be somewhere in between a concentration of 0.4 and 0.6. One source of error for this lab is that the amount of substance placed into each Dixie cup was not measured and therefore were not consistent. If this lab were repeated, it is suggested that the amount of substance be measured in order to produce more consistent results.…

    Aim To observe and measure the effect of osmosis on the mass of potato using a starch solution. Introduction In order to measure the effect of osmosis, eighteen pieces of potato were cut and placed in six groups, each group of three pieces cut to weigh as close as possible to one another. For each potato group, a test tube was half filled with a starch solution varying in concentration from 0% (water) to 1%. Hypothesis…

    The purpose of this lab was to observe the rate of osmosis and diffusion, as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion, that dealt with raisins in different liquid environments, each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration, by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases, the objects in a greater concentration of the substance were stripped of their water. However, where there was a little or no concentration of sugar or salt, the objects did not lose their water, and in the case of the raisin, became saturated with excess…

    Introduction: Osmosis is the diffusion of water from a higher concentration to a lower one through a semi-permeable membrane and occurs in the cells of organisms. It is affected by the addition of solute which would lower the water potential, making water potential and solute concentration inversely related. The concept of osmosis loosely described is that the presence of more solute outside the cell means the presence of less solvent (or water molecules in this case) and vice versa; the goal of osmosis is for the water molecules inside and outside of the cell to be equal, causing equilibrium and a stop to net water movement. The goal for a recent lab was to test whether cubes of potato would gain or lose weight depending on the amount of molar concentration of sucrose they soaked in. Solutions made of different molar concentrations of the solute sucrose were prepared before this lab. Potato cubes were weighed and recorded as the initial mass in the data. Four cubes of potato were placed into 100 mL of each solution and let stand overnight. The cubes were then taken out for the final total mass to be measured and recorded. In this experiment, the potato cubes were the dependent variables, and the molar concentrations were the independent or manipulated variables.…

    The purpose of this experiment was to test different solute concentrations on the rate of osmosis. Artificial cells were filled with different solute concentrations and placed in water and weighed at equal time intervals to show how the water moves across cell membranes and down its concentration gradient into the lower concentrated area. The weights of the cells were recorded each interval, and then the rate of osmosis was found by calculating the corrected cumulative change in weight. The prediction made was that the cells with the higher solute concentrations would have a higher rate of osmosis and the cell filled with water and placed in 40% sucrose solution would have the highest negative weight change.…

    Diffusion is simply the net movement of atoms or molecules from a region of higher concentration to a region of lower concentration. The force behind the movement is heat or kinetic energy (also called Brownian motion). Diffusion occurs when you spill water on the carpet floor and it spreads out, or when you open a bottle of perfume and it leaves the bottle and spreads throughout the air in the room.…

    The aim of this experiment was to test the effect of surface area on osmosis and the effect of solute concentration on osmosis. To test this aim to hypotheses were devised. 1) If potato pieces are immersed in various salt solutions, then the pieces with the greatest surface area to volume ratio will experience the greatest weight change, because more water can move by osmosis across the potato cell’s semi permeable membrane. 2) If potato pieces are immersed in various salt solutions, then the pieces immersed in the most concentrated solution will experience he greatest weight change, because more water must pass across the potato cells semi permeable membrane by osmosis to achieve an equilibrium. The results from testing these hypotheses did not support either and were shown to be flawed because they did not reflect the theories of osmosis relating to surface area to volume ration and salt concentration.…

    The reason of this experiment was to identify the properties and effects of osmosis. Osmosis can be defined as the diffusion of water through a selectively permeable membrane. (Miller/Levine) Osmosis occurs when there is an area of higher and lower concentration. Osmosis is a type of diffusion. Diffusion is when molecules move from an area of higher concentration to an area of higher concentration. The three types of concentrations are hypotonic, hypertonic, and isotonic. When in comparison to another solution, a hypertonic solution has a lower concentration, a hypertonic solution has a higher concentration, and an isotonic is when the two solutions have an equal concentration. The experiment tested the relationship between the concentration of an egg and solutions of different concentrations. The hypothesis is that an egg placed in distilled water will gain mass while an egg placed in syrup would lose mass.…

    This overall flow of water from a dilute area of high water potential to a more concentrated solution of low water potential across a partially permeable membrane is called osmosis. I predicted that the swede cylinders which are put in a test tube with a low potential of sucrose solution would become turgid because the water molecules that are present in the swede will move away from an area of higher potential of water molecules to an area that has a lower potential of water molecules, this means that the swede sample will gain mass and become full almost to an extent where it is ready to burst. The swede samples that are going to be put in a test tube with a high potential of sucrose solution will become flaccid because the swede cylinder will have a higher potential of water molecules and so these molecules will diffuse into the sucrose solution as it has a lower water potential, this means that the potato sample will shrivel and loose mass.…

    The results seen in the water control as well as possibly the 0.2M sucrose occur because the water potential outside of the potatoes would be higher thus encouraging water to move into the potatoes and increase their mass. In other words, osmosis (diffusion of water from high to low concentration across a membrane) occurred and moved water from the environment hypotonic to the carrot into the carrot itself in an attempt to equalize concentration between them. In the higher molarity sucrose solutions, water’s potential is higher inside the potatoes—the water content of the carrots is more pure than in the outside solutions. Thus water would move out of the carrots into the…
