Osmosis Lab
Mylana Gerard December 20, 2012 10D
Introduction:
The cell membrane is a protection from anything outside the cell and anything inside of the cell. The purpose of the cell membrane is to selectively choose what comes in the cell. It’s permeable and able to regulate what enters and exits the cell, which is facilitating the transport of materials needed for survival. Cell membranes aren’t in just one specific kind of cell because it’s in every cell. The cell membrane is supposed to hold up the structure of the cell keeping all organisms in alignment. Osmosis is the movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration, in order to equalize the solute concentrations on the two sides. We didn 't know anything about osmosis except that it was a word in the dictionary that we never picked up. Osmosis and diffusion are similar because osmosis is the result of diffusion across a semi-permeable membrane. If two solutions of different concentration are separated by a semi-permeable membrane, then the solvent will most likely to diffuse across the membrane from the less concentrated to the more concentrated solution, which is osmosis.
Some real life events of osmosis are cells in the human body and in the bodies of all living things behave like microscopic bags of solution housed in a semi permeable membrane. The health and indeed the very survival of a person, animal, or plant depend on the ability of its recovery. Osmosis has several implications where medical care is concerned, particularly in the case of the storage of vitally important red blood cells. These are normally kept in a plasma solution, which is isotonic to the cells when it contains specific proportions of salts and proteins. However, if red blood cells are placed in a hypotonic solution, or one with a lower solute concentration than in the cells themselves, this can be highly detrimental. The purpose of this lab is to

    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.…

    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…

    Vinegar Egg Lab

    When the experiment was finalized the vinegar solution enlarged the eggs mass. Before the vinegar solution it was 55.1 grams and after the solution it was 67.9 grams. The volume of the egg was also increased. At the beginning it was 50 mL after the solution it was 60 mL; it had a 10 mL difference. It is visible that a hypotonic solution was present. This rejects the hypothesis made. When the egg was placed in 150 mL of vinegar and left intact overnight the egg did sink to the bottom and remain that way, however, the mass was increased instead of keeping it the same, by approximately 13 grams. Furthermore, the volume was also increased it did not remain the same. By analyzing the data it can be determined that the water had a larger concentration and did not have to balance out with the vinegar. The vinegar acted in a peculiar way although it eroded the shell and took some weight off the water flowed inside the egg due to the low concentration of the vinegar.…

    Cells must move materials through membranes in order to maintain homeostasis. The cellular environment is aqueous, indicating that the solutes dissolve in the solvent, water. When a cell is hypertonic, or hypotonic, to its surroundings, it tries to make concentration of solution inside and outside itself equal. However, the solutes are too big to pass the cell membranes without the help of channel proteins, or transport proteins. Water may freely pass through the membrane by osmosis, which requires no energy. Thus, the cell starts to take in, or release, water until it is isotionic to its…

    The purpose of this lab is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic, isotonic, and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell, it keeps the cell the same it’s just in a different environment.…

    The lab for this paper was conducted for the topic of osmosis, the movement of water from high to low concentration. Five artificial cells were created, each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic, hypotonic, or isotonic solutions for a period of 90 min. Over time, the rate of osmosis was measured by calculating the weight of each artificial cell on given intervals (every 10 minutes). The resulting weights were recorded and the data was graphed. We then could draw conclusions on the lab.…

    Egg Osmosis La1

    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.…

    A cell membrane is a very significant function in the human body. In one sense, it is used as a barrier to keep the enzymes, DNA, and metabolic pathways that bundles everything together. Cell membranes are also used as a gateway for waste projects that must be discharged and essential materials (oxygen, water, etc.) must enter through it. When a membrane is called semipermeable, it means that it will allow certain molecules or ions to pass through it by diffusion and occasionally specialized facilitated diffusion. When the cell membrane expends energy, it is known as active transport, or when the process is driven by kinetic energy, it is passive transport.…
