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:

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

The plasma or cell membrane exhibits ability for the cell to discriminate in its chemical exchanges with its environment and this makes cell membrane fundamental to life. This property can only be possible because of the cell membrane’s selective permeability (Campbell and Reece‚ 2002). The structure of the membrane can be best illustrated by the fluid mosaic model where the membrane is said to be a fluid structure with various proteins embedded in or attached to a bilayer of phospholipids (Campbell

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

Cell Phones in the Hands of Drivers A Risk or a Benefit Ariana Laguna English 102 Professor Barnes/Walter 10 December 2012 Outline THESIS: Unless the risks of cell phones are shown to outweigh the benefits‚ we should not restrict their use in moving vehicles: instead‚ we should educate the public about the dangers of driving while phoning and prosecute irresponsible phone users under laws on negligent and reckless driving. I. Scientific studies haven’t proved a link between use of
