Lab 4: Osmotic regulation of cell volume

The eukaryotic organism requires homeostasis to maintain daily activities and life. Zooming into smaller units to make up an organism, cells also require homeostasis in order for the organisms to function. Understanding the different balance cells need to maintain will aid us in understanding how cells in organisms successfully maintain osmo-regulations. Eukaryotic cells have selective permeable membrane giving them the unique function of regulating specific molecules between the intracellular and extracellular environment. This experiment will help researchers understand how cell maintain its’ cellular regulations. For this reason, the specific cell chosen to further understand the osmotic regulation

The role of red blood cell is to transport gas and ions to all other cells in the body (Body Systems and Homeostasis; Diez-Silva). Individual cells also need to maintain a specific structure in an environment to function properly. Therefore they must maintain a balance between the amount of gas like oxygen, liquid such as water, and solid ions to maintain homeostasis. According to the Oxford dictionary, homeostasis is the equilibrium maintenance of interdependent elements of physiological processes. To observe homeostasis, we would look into osmolarity. Osmolarity is a concentration measurement of particles using milliosmoles per liter (mOsm/L). The difference between molarity and osmolarity is that osmolarity takes pressures into account. Osmolarity only calculate the amount of particles difference between the intracellular membrane and the extracellular of the membrane. The …show more content…
From the second part of the example, cell burst is a possible situation can occur to the cell. In this experiment, cell burst, more specifically hemolysis, red blood cell death, lead organelles to spread in the solution and block the absorbance of light in the colorimeter. By comparison of the measured osmolarity and hemolysis between the different solutions provided the data to understand, how a red blood cell react in different osmolarity to maintain

    An osmotic problem Paramecium faces is that excess water enters the cell because it is hypotonic to its environment. As a result, they need to use contractile vacuoles to get rid of excess water in the cell, enabling it to osmoregulate. Compare the ideal osmotic environment for animal cells and plant cells The ideal osmotic environment for animal cells would be if it were isotonic, meaning the cell and the environment have the same concentration of solutes and water, so the cell won’t change. The ideal osmotic environment for plant cells would be if it were hypotonic, meaning the environment has a lower concentration of solutes but a higher concentration of water than the cell, so the cell would gain water from its environment and grow.…

    Room 337 Case Study

    Room 337, an 85- year old widowed white female, presented six days ago to Lynchburg General Hospital with complaints of dizziness and falling. She has a past medical history of hypertension, chronic CHF, asthma and hypothyroidism. After the conduction of lab testing, Room 337 was diagnosed with syncope. Her syncope was most likely a result of insufficient O2 delivery to the brain caused by a decreased CO produced by the weakening of her heart muscle. Despite hypertension medications, Room N337’s dizziness and muscle fatigue persists demonstrated by fluctuations in her orthostatic BP readings reflecting the inability to get out of bed and move freely.…

    This lab provided a good perspective of the movement of molecules diffusing and going through osmosis into a cell. The ability of the cell membrane to be selective was illustrated by it not allowing all the molecules through (starch). This shows how in a real cell it can differ between essential and nonessential or invading molecules. Lastly, It gave a good example of hypertonic solutions and how the concentration gradient…

    Osmosis being the main theme of it all, but without the plasma membrane, none of this could happen. This experiment gives an idea as to what happens when a cell experiences both a hypotonic state and hypertonic state. A real world example of a hypotonic state is when a cactus stores/soak up water in order to survive in the desert biome. A good example of a hypertonic state is when grass becomes dry, the area surrounding it may full of water but the inside the grass it is barren. The experiment explained the processes of a hypertonic state, where the egg began to shrink due to the water leaving the egg as well as hypotonic where the water entered the egg.…

    Observing the Effects of Osmosis on Model Cells of Different Sucrose Concentrations Cells are the building block of life. But these cells aren’t a closed system. There is a constant movement of various molecules in and out of the cell that brings nutrients in and brings waste out. This movement of particles in and out of cells is based around osmosis.…

    This experiment showed the important of osmosis by showing how the tube that represents the cells in side us react when placed in different situations. This is very important to know in the medical field, when deciding how to keep our cells healthy and alive. Like when a person is being treated for dehydration, the doctors know what percentage of saline to put in us that it will not swell and eventually burst our cells. By watching osmosis make a cell hypertonic, hypotonic, or isotonic, we have a deeper understanding on why this subject is so important for our overall health and much…

    The purpose of this EEI is to create and analyse an experiment that relates to and supports the theory of osmosis in biological cells. Cells are the biological building block for all life; all living organisms have cells also. Cells provide structure, absorb nutrients from food and convert those nutrients into energy so that the cell can carry out specialized functions. There are two main categories with most organisms and their cells; prokaryotes and eukaryotes. The distinctive difference between prokaryotes and eukaryotes is that eukaryotic cells contain membrane-bound organelles, such as the nucleus, while as prokaryotic cells do not.…

    The red blood cells, scientifically known as Erythrocytes, makes up 40 percent of the blood’s volume. Erythrocytes contain an iron filled protein called hemoglobin, which gives the blood its red color. Hemoglobin allows the Erythrocytes to carry oxygen from the lungs and bring it to all of body tissues via blood flow in the circulatory system. They also bring carbon dioxide away from the tissues back into the lungs.…

    Movement of cells are important since some cells depends on movement to carry out its major function. For example, sperm cells need to move from one place to another place to carry out reproduction. Movement of cells are supported by cytoskeleton system of the cells. The cyctoskeleton system are composed of microtubules, microfilaments and intermediate filaments. However, for unicellular organisms such as Paramecium, the movement of cells are regulated through cilia or flagella.…

    Osmosis is when molecules pass through a semipermeable membrane from a less concentrated solution into a more concentrated one. Because water loses energy it is thus becoming equal or at equilibrium (Shadish, Harris, Tellekamp 2017). This is the point where the concentrations in both areas are equal and no net movement will occur from one area to another (Lab 1 Osmosis). In this lab we observed how molecules move across the cell membrane. The question this lab is answering is how materials within a cell move.…

    Osmosis is the net movement of water towards higher concentration. In osmosis experiment, water likes to diffuse from an area of low-solute concentration to an area of high-solute concentration. The purpose of the osmosis experiment was to observe the diffusion of solutes and the osmosis of water through a semipermeable membrane, which was dialysis tubing. This experiment was done to examine, if the solution is hypertonic, hypotonic or isotonic.…

    Part 1 DB 2 “The plasma membrane allows fluids or gases to pass or diffuse through to specific molecules. It allows nutrients and other vital elements to enter the cell and waste materials to leave the cell. Oxygen, water, and carbon dioxide pass freely across the membrane, but amino acids and sugars are carefully regulated (University, 2015).” When thinking of an analogy for plasma membrane, what comes to mind it the stomach and digestion of food and how it reacts to food, filter foods, and separates food and nutrients. For instance, the digestive tract begins in the mouth.…
