Osmosis Research Paper

824 Words4 Pages

Factors Affecting the Rate of Osmosis I. Research Question: How does the amount of Monosodium glutamate or MSG (C5H8NO4Na) concentration affect the osmosislarity of cow (Bos taurus ) liver cells? II. Background information Osmosis is the diffusion of water molecules through a partially permeable membrane from a region of high water concentration to a region of low water concentration. The factors affecting the rate of osmosis are temperature, concentration gradient, molecular size, surface area to volume ratio, and permeability. Animal liver cells, such as cow liver cells have a nucleus, cytoplasm, and a cell membrane. The nucleus contains the DNA, genetic material that controls the cell. The cytoplasm is where the processes take place and are controlled by enzymes. The …show more content…

Though I will be experimenting on cow liver cells for ethical reasons and because both are animal cells. Experimenting on cow liver cells, I can assume that the results would be similar if done on human liver cells. To learn how dangerous Monosodium glutamate can be to our body, I plan to use this experiment to see the effects of Monosodium glutamate on cow liver cells, and reflect how it may also affect human liver cells. III. Hypothesis When there is a gradient of high water concentration to low water concentration, the water molecules will move faster, and when there is a gradient of low water concentration to high water concentration, the water molecules will move slower, therefore, the rate of osmosis will be faster the water concentration is from high gradient to low gradient. My hypothesis is as the concentration of Monosodium glutamate increase, the mass of the liver cell also increases. This is because of osmosis and how the liver cell submerged in the solution allows Monosodium glutamate to pass to the permeable layer of the liver cell. IV. Variables Types of Variable Measurement How to

  • Why Do Red Blood Cells Distilled Water

    700 Words  | 3 Pages

    Red Blood Cells Red blood cells will change shape in response to the evolving environment. For instance when distilled water is added to red blood cells, the red blood cells seem to expand. Why does this natural phenomenon cause red blood cells to appear considerably bigger after being exposed to distilled water? We tested two theories of why this happens. Theorem one is that molecules such as protein and polysaccharides are more concentrated inside the cell than outside the cell when the cell is in distilled water.

    a.) The nucleus of a eukaryotic cell is surrounded by two phospholipid bilayer membranes, with nuclear pores connecting them and regulating the movement of materials between the nucleus and the cytosol (1). The nucleus of a eukaryotic cell is the largest organelle, and within in it is the DNA. The DNA within each cell is identical within every cell in an organism, with only small differences due to mutations. The DNA within a nucleus is consists of two chains of combinations of Adenine, Thymine, Guanine, and Cytosine, with each chain held together by a Phosphate-deoxyribose backbone (1).

    Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.

    For this lab I will be using water and sucrose to demonstrate the rate of osmosis. In this lab I will be exploring how temperature impacts the rate of osmosis by placing pieces of potato of equal size in solutions of different temperatures and observing the change in mass of potato after a given period of time. The change in mass will indicate the rate of osmosis.

    Desalination is the process through which dissolved minerals and salts are eliminated from water, including seawater, saline water, brine water and brackish water. Through desalination, the water that was not suitable for drinking is converted into potable water. The popularity of desalination has continued to increase over the years due to rapid increase in global population and water demand, environmental changes such as frequent droughts, land encroachment, among other human activities. Conventional methods of desalination were only focused on eliminating salts from seawater but newer technologies have made it possible to desalinate even other wastewater containing impurities including salty groundwater, rivers, industrial effluents, etc. (Kellyn Betts, 2004) Technology has been an important factor in scaling up desalination process to meet various treatment design plants.

    Osmosis is the diffusion of water. This means that osmosis refers specifically to the movement of water across a semi-permeable membrane down a water concentration gradient. Therefore, completing this experiment will allow us to come to a conclusion as to how much a solute concentration gradient affects osmosis across semi-permeable membranes, and how we can apply what we have learnt to the world surrounding us. Relation to Semi-Permeable Membranes within the Context of our Experiment: In this experiment, we will explore the specific movement of

    In hospitals patients sometimes receive fluids by intravenous injection. Doctors choose a salt solution and never plain water to inject into humans. You know that blood is composed mainly of red blood cells. Use your knowledge of osmosis to explain why doctors make this choice? Osmosis is the diffusion of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration.

    In the lab that was conducted, cell structures and functions were observed. Most cells have a nucleus, cell membrane, cytoplasm, ribosomes, mitochondria and other organelles. Another important organelle is the nucleus. This is where the DNA is held and it contains the hereditary material of the cell and it controls the cells activities (1). Cell membranes are selectively permeable, which means that the cell can decide what can pass through and what can’t, and are made of phospholipids and proteins.

    The experimental hypothesis for this experiment was prove as the results from the experiment provide evidence to suggest so. The osmosis process was shown when the potato cylinders were submerged in the salt solution and over time this only became more prominent. Looking at graph A, the potato cylinders submerged in the water solution gained mass and became harder when pressure was applied. This meaning no osmosis happened as expect as the mass gain implies there was just passive transport. The water molecules in the water solution were small enough to pass through the semi permeable membrane in order to equalise so there was a balance between the potato and the water solution.

    A tightly regulated volume tracks water excretion and how the total amount of blood volume has a direct effect on plasma osmolarity. As a result, plasma volume has a direct effect on the blood pressure. When the blood contains low amount of water, plasma volume decreases and serum osmolality increases, that can lead to blood having an increase in viscosity (Evans 1. et al. 1506).

    Biology Design Practical Joshua Edwards What are effects of the volume of a potato and the amount of weight it loses when placed in salt solution? Introduction This design practical uses a potato’s surface area to volume ratio to see what affects it has on osmosis in different concentrations. Osmosis is the movement of water molecules through a cell membrane into an area of a higher solute concentration. The movement goes the way of the solvent with more solute because the lower solute concentration is drifting through balancing the ratio of solute per solvent (En.wikipedia.org, 2018).
