Egg Osmosis
Osmosis is the passive movement of solvent molecules across a membrane. NaCl, salt, triggers osmosis to occur as it attracts the water which moves towards it across the membrane. The NaCl, salt, is a solute. Adding water to a solute causes it to spread out the concentration of salt, creating a solution. The eggs initial weight compared to the weight after being submerged in the distilled water showed immediate osmosis. The egg internal solution contained some level of salt witch attracted the distilled water to move into the egg. As the concentration of NaCl increased, 1%, 2%, the rate of change decreased slowly equalising the salt and water levels. When the concentration of salt inside the cell is the same as the concentration of the salt

    Introduction: The biological membranes are composed of phospholipid bilayers, each phospholipid with hydrophilic heads and hydrophobic tails, and proteins. This arrangement of the proteins and lipids produces a selectively permeable membrane. Many kinds of molecules surround or are contained within cells, but water is perhaps the single most important molecule in any living system (Hayden and McNeil 2012). Since water molecules are so small, they are constantly going into and out of the cell. Osmosis is a situation where more water molecules are moving across the membrane in one direction than the other (Hayden and McNeil 2012). During osmosis the net movement of water molecules will be from a solution that has a lower osmotic concentration to a solution that has a higher osmotic concentration. When a solution has a higher concentration of solute within the cell than out, it is called hypertonic. When a solution has a lower concentration of solute within the cell than out, it is called hypotonic. And when there are equal concentrations inside and out of the cell, it is called isotonic. The relative osmotic concentration can be determined by a change in mass of the tissue.…

    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…

    Throughout the six days of recording data, osmosis did occur. We soaked our egg (Eggar) in “Super Chill Peach Sparkling Water.” Eggar gain weight as he grew larger. He soaked up the water when he was in the sparkling water, so he could have an equilibrium. He was squishy, smooth, and (slightly) transparent too. On the last day Eggar was soaked in water, and he then lost weight. When we took him out of the water we noticed we had an air bubble inside of him. The liquid started with a higher water content, then due to osmosis, they had an equilibrium. The reason he must have lost weight when in water is Eggar had a higher water…

    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.…

    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.…

    An egg is a model of a human because the egg has a cell membrane like humans do inside and outside of the body that let things pass through like water. We can use eggs to study the effect of changes in the external environment on the internal environment by having harsh environments like putting the egg in only alcohol and see what happens to the inside of the egg. Diffusion is the movement of a substance down its concentration gradient from a more to a less concentrated area. Meaning if there was more oxygen on one side of the membrane and the membrane was permeable to oxygen, the oxygen would pass through to the side of less oxygen. Osmosis is the movement of water across a selectively permeable membrane. Diffusion and osmosis is important for organisms because our nutrients, oxygen, and etc., need diffusion to go through compartments. I predicted that the more the concentrated the alcohol solution was the mass would increase because I thought the membrane would let alcohol through which would cause the egg to expand.…

    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.…

    Osmosis And Diffusion

    Osmosis is the diffusion of a solvent across a selectively permeable membrane that occurs in response to differences in solute concentrations (Allen and Harper 2014).Osmosis can fall under the category of passive transport which does not require energy. With osmosis being a type of diffusion it is viewed as molecules moving from a high concentration to a low concentration. To further explain if there is a low water concentration, high amounts of solutes will be present. Water will most likely move to areas where the solute concentration is high, which demonstrates why there would be less water concentration.…

    Colligative Properties

    Several experiments were performed to observe the colligative properties. This includes the freezing point depression, and osmotic pressure. Two ice baths were made, one with pure water, the other with salt water. The lowest temperature was then record for each bath and compared. The salt water had a lower freezing point than the pure water by 2 degrees which supports the hypothesis that solutions have a lower freezing point than pure water. The second property observed was osmosis pressure. This experiment used a 6 inch piece of dialysis tubing that was filled 2/3 full with light Karo syrup and tied off. Then it was completely submerged in a large glass bowl of room temperature distilled water. The dialysis tubing acts as a semi-permeable barrier and water passed through to inside the tube and over the next several hours, this act caused the tube to swell. Osmosis is where water moves from an area of high concentration to low concentration, therefore causing the tube to swell. The last experiment involved placing an egg in a jar of vinegar. After 24 hours, the shell of the egg completely disintegrated. Then the jar was rinsed and refilled with Karo syrup where the egg was submerged for 48 hours. This allows osmosis to take place where the water inside the egg leaves and moves outside where thereis a lower concentration of water. Thus, making the mass of the egg smaller.…

    INTRODUCTION: In order to fully understand the concept of this experiment, one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The progress in which a cell is in its balanced state is called equilibrium. Diffusion is a functioning way for cells to reach their equilibrium. Equilibrium is reached by controlling what enters and exits the cell through a cell membrane that selectively filters molecules by slowing down their movement, allowing them to pass through, or not allowing them to pass through the membrane. Diffusion and osmosis go hand-in-hand. Osmosis is generally the same as diffusion, however, deals solely with water. Osmotic pressure is the pressure of a solution against a semi-permeable membrane to prevent water from flowing into the membrane. In this lab, we are going to study tonicity; tonicity is the measure of this osmotic pressure and is the differential of pressure between two solutions separated by a selective membrane. To help identify the relative concentrations of solute particles of different solutions, we must understand that there are three possible differences in concentrations between a cell and its environment. The terms hypotonic, hypertonic, and isotonic are used in referring to the identification of the possible relative concentrations. The first term, hypotonic, is the solution that contains lower concentrations of solute particles, which means that the concentration inside the cell is greater than the concentration outside. A hypotonic solution causes the cell to swell in size. The second term, hypertonic, is the solution that contains higher concentration of solute…
