BIOL 2010 ANATOMY AND PHYSIOLOGY I Chapter 4: TISSUES AND MEMBRANES Outline of Notes I. Introduction. A. General: Cells are highly specialized and interdependent on one another. Groups of similar cells performing similar functions are called Tissues The study of tissues is called Histology. Organs are made of tissues. A detailed understanding of tissues will greatly help your understanding of organs and organ systems later in this course. Tissues are classified into 4 main types:

In this laboratory experiment is stating that organic lipids have the ability to dissolve lipids membranes‚ and in this exercise acetone would be the main source to be used to have the reaction of dissolving the lipids inside the tubes. This exercise was to be able to observe how the chemicals reacted in rare temperatures such in heat and in cold weather‚ also this type of changes can create a new color either making the color lighter or darker. The reaction of a light color would be that it did

Epidermis Cells Aim: To see if rhubarb changes when it is placed in solutions of different concentrations. Introduction: "Plasmolysis in Rhubarb Epidermis Cells" is an experiment to see whether or not rhubarb changed its cell structure when placed within different types or solutions. "A single layer of plant cell is placed on a micrscope slide and either distilled water or 5% NaCl solution is added to the cells. Osmosis will occur resulting in either turgid cells or plasmolysed cells." (www

of the cell membrane with the correct terms integral proteins‚ channel proteins and bilipid construction. Your last paragraph was very detailed with great information about the cell membrane‚ you stated “ The cell membrane is very thin and fragile‚ and it contains two different types of proteins. “Integral proteins are part of the membrane structure and cannot be removed without damaging or destroying the membrane. Peripheral proteins are bound to the inner or outer surface of the membrane and are

Water Transport The movement of plants from water to land has necessitated the development of internal mechanisms to supply all the parts of the plant with water. As discussed in Plant Classification‚ Vasular Tissues ‚ tracheophytes (including virtually all terrestrial plants except for mosses and liverworts)‚ have developed complex vascular systems that move nutrients and water throughout the plant body through "tubes" of conductive cells. The vascular tissues of these plants are called xylem

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

048: Problem Set Questions 1. Given that cell A has significantly more nongated K+ channels than cell B‚ which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular

by using the application of membrane have become highly demand in various industries. In this newly separation process ‚ the membrane function as a semi-permeable barrier and the separation process occur by the membrane controlling the rate of movement of various molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality and quantity of water for production. Membrane process can be used to separate

Practical 2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.
