Cell Surface Glycoprotein Receptor Analysis Using Concanavalin A Purpose: During this experiment we compared the hemagglutination reaction of control Con A solution at 2 mg/ml in Con A buffer with the hemagglutination reaction of your own purified Con A sample that you diluted previously at 2 mg/ml in Con A buffer. The purpose of this lab was to determine the strength of the reaction by performing serial dilutions on both the Con A sample and the control Con A sample‚ and determine through observations

GAIN MUSCLES. Introduction. The assignment topic touches on a very important part of the human body a muscle. This is a soft tissue found on most animals and is made of cells that contain protein filaments of actin and myosin that slide past one another‚ producing a contraction that changes both the length and the shape of the cell. It function to produce force there location on the body or according to the functions and roles they play. They are the cardiac muscles (muscles covering the heart)‚ the

Testing Cell Transportation Across a Membrane Introduction Cells have the amazing ability to transport certain molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live

CELL REPRODUCTION DNA is the cell’s genetic material; chromosomes are the carriers of this genetic information. In proka-ryotes‚ the chromosome is a single circle of DNA. In eukaryotes‚ each chromosome is a complex of DNA and histone proteins found in the nucleus. BINARY FISSION Prokaryotic cells reproduce via binary fission. In this process‚ DNA Is replicated‚ and the cell splits in two roughly equal parts‚ each with a copy of the cell’s DNA. EUKARYOTIC CELL CYCLE Eukaryotic cells reproduce

2012 Tuesday‚ October 9th‚ 2012 Comparing Plant and Animal Cells Abstract The purpose of our lab was to have a better understanding of what are the differences between animal cells and plant cells. Although the cell is the basic unit in both living beings they are not completely alike. For that I have examined and compared human cheek cells to Elodea leaf cells. First‚ I’ve scraped the inside of my cheek with the end of a swab stick to collect the cells then I’ve prepared them on a clean glass slide

potential difference in voltaic cell. Aim: To investigate the effect of concentration of electrolyte of the potential difference in voltaic cell. Introduction: Chemical reactions involving the transfer of electrons from one reactant to another are called oxidation-reduction reactions or redox reactions. In a redox reaction‚ two half-reactions occur; one reactant gives up electrons (undergoes oxidation) and another reactant gains electrons (undergoes reduction). Voltaic cell is a device in which a

single cell to divide and produce all the differentiated cells in an organism‚ including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes. Zygotes are the products of the fusion of two gametes. In some organisms‚ cells can dedifferentiate and regain totipotency. For example‚ a plant cutting or callus can be used to grow an entire plant. Human development begins when a sperm fertilizes an egg and creates a single totipotent cell called

Effects of Tonicity on Cell Membrane Abstract The purpose of this experiment was to determine the effects of tonicity on a cell membrane using red blood cells‚ potato strips and three unknown solutions (A‚ B‚ C). First three slides were prepared containing RBC’s and unknown solutions A‚ B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The
