Download file to see previous pages Cells put in isotonic solution showed no change in morphology. These results are the bases for infusing intravenous fluids to patients by health care professionals. The effect of temperature was determined by placing potassium permanganate in a beaker of water and subjected to different temperatures. A significant increase in the rate of diffusion was observed in the sample subjected to 60 degrees centigrade than those subjected to lower temperatures.
The human body is made up of different organ systems which work together in maintaining an environment that is most beneficial to the organism. These systems have several mechanisms all aimed at regulating the different bodily processes. The plasma membrane plays a very important role in protecting the cell as it regulates the substances that go in and out of the cell. This ensures that the substances that go inside the cells are vital for cell functions and that harmful substances are discarded. This study has been conducted to demonstrate diffusion and osmosis, to define hypertonic, hypotonic and isotonic solutions, to measure packed cell volume and investigate how erythrocytes react to the different solute concentrations.
To determine the effect of different solute concentrations on red blood cell, blood samples were mixed with the different solutes in properly labeled test tubes. The turbidity of the solution was then determined by placing the test tubes against a printed page of a book. To support the observations on the test tubes, samples were also collected from the tubes using Pasteur pipettes and were put in glass slides and were viewed under the microscope with the magnification of 10x40. The results were then tabulated and recorded in table 1. The packed cell volume of the blood samples was also determined by taking 15ml of blood samples by using capillary tubes. The unfilled end of the tubes was then sealed with cristaseal. ...Download file to see next pagesRead More

White Blood Cells (WBC)

...? White Blood Cells (WBC) White Blood Cells (White Blood Cells: Battling Blood Cells, Our Blood consists of Red and White Cells which have important role in maintaining our body healthy and keeping bodily metabolisms intact. White Blood Cells (also called leucocytes) are responsible for keeping our immune system working all the time to prevent the intrusions of foreign materials or infectious diseases into our body. Bone marrow is the producer of White Blood Cells. The major function of Hematopoietic stem cells, found in bone marrow, is the production of WBC. Hematopoietic stem cells have a life span of only three to four days and therefore, any deficiencies in the production of this stem cell may affect the production of WBC also...

Diffusion and network effects

...?Topic: The Diffusion of Facebook and Network Effects Introduction Facebook, which currently has a user base of over a Billion active users, was founded in 2004 by March Zuckerberg (Fowler, 2012). In 2012, the annual revenue of the organization was $5.1 billion and during the initial public offering which took place in the same year, the organization was valued at $104 billion (Sengupta, 2012 ). Facebook is known for regularly coming up with innovations such as timelines, in-built chat services, ads and common interest groups, which enhance the user experience. 2. The Diffusion Process for Facebook According to Rogers (2005) Diffusion of Innovation takes place through a heterogeneous type of adopters, who are characterised by their own...

Diffusion and Osmosis Lab Report

...Diffusion and Osmosis Laboratory Report For a cell to survive, the exchange of water from outside to cell to inside and vice versa is extremely important since water serves as the medium for transport of metabolic ingredients and byproducts. It can occur mainly through two biophysical processes, osmosis and diffusion. Depending on the biological process, the cell exerts its option of choosing either of the two in a given exchange process. Physical movement of water occurs in both of these processes depending on the physical characteristics of the solutions that are being exchanged. The cell and its extracellular environments are fluid in that concentrations of substances dissolved in it vary. Depending on varying concentration...

Diffusion and Osmosis

...Diffusion and Osmosis - Introduction One cannot overestimate the importance of such simple, yet essential processes like diffusion and osmosis. Whilethe former represents a movement of molecules of substance from a region with higher concentration of that substance to a region of lower concentration, the latter usually refers to a process of movement of molecules through a semi-permiable membrane. Since the cell membranes represent semi-permiable membranes, the processes of diffusion and in particular, osmosis, are clearly evident. The importance of these two processes is based on the fact that they determine the distribution of nutrients and the disposal of waste products of metabolism. One particular example is the absorption of water...

...Osmosis Experiment with Swede In this experiment, I tried to find out the effect of osmosis on slices of swede, a root vegetable, immersed in a pan of water solution. Osmosis is a process where water passes in or out through the tissue of the plant or vegetable. This process explains how plants or vegetables absorb water into its cells or release water from its cells. How does osmosis take place A plant or vegetable is full of cells that contain water. Each of these tiny cells is surrounded by a membrane like our skin. The membrane protects the cell by keeping its parts inside and keeping other things outside. This membrane can stop many things from entering the cell, but it cannot keep water out. Water can pass through the membrane...

Investigate osmosis in blood cells

The cellular geometry, that is, the biconcave disc shape of red cells, is critical for the cells' survival. This cell surface shape provides a high ratio of surface area to cellular volume. The normal volume of the erythrocyte is approximately 90 m3. The minimum surface area that could encase this volume is a sphere of approximately 98 m3. The surface area of a biconcave disc enclosing this volume is approximately 140 m3. Thus, shape alone provides the red cell with a considerable amount of redundant membrane and cytoskeleton. This feature provides the extra membrane surface area needed when red cells swell. More importantly, this geometric arrangement allows red cells to stretch as they undergo deformation and distortion in resp...

Diffusion and osmosis

.... The first part demonstrated the effect of temperature on the rate of diffusion. Crystals of potassium permanganate were placed in beakers which were subjected to different temperatures. Changes in the solutions were observed over a period of time. Observations were noted and recorded at 0 minute, 5 minutes and then at 10-minute intervals for the first hour, and then again after every 20 minutes thereafter. To demonstrate the effect of osmosis on red blood cells, six test tubes were prepared and were labeled test tubes A-F. Two (2) ml of different solutions were placed in each tube with the use of a Pasteur pipette. Two (2) ml of blood was then added to each test tube. After mixing by inversion, the tube was placed in front...

Diffusion and osmosis

Diffusion is the molecular process by which certain particles move from a place of higher concentration to a location of lower concentration containing those same particles. It moves from the higher to the lower concentration because of the concentration gradient which is the difference in concentration levels between two adjacent regions. Diffusion stops when the concentrations between these two becomes equal or has reached equilibrium. Osmosis is simply a type of diffusion in which water moves from high concentration to that of the lower water concentration. Both processes, diffusion and osmosis, are examples of passive transport (see fig. 1). It means that there is no energy required to facilitate these processes. In biology,...

Red Blood Cells Cytoskeleton

...Your full November 18, Red Blood Cells Cytoskeleton Red blood cells have a specific biconcavedisc shape. This characteristic enables them to optimize their ability of gas exchange. They have a 120 day life span, and throughout this course, the red blood cells experience high intensity sheer force while moving through narrow capillaries in the microvasculature. This results in fast but reversible deformations in their structure. Thus, there is special cytoskeleton that the red blood cells are equipped with, which helps them to combat this sheer force by providing them enough mechanical firmness and elasticity. The membrane of a red blood cell is a lipid bilayer with transmembrane proteins and a myriad of filamentous proteins along the whole...
