Date: 28/11/13 EVALUATION OF THE EFFECT OF SODIUM CHLORIDE ON ONION EPIDERMAL CELLS INRODUCTION A living plant cell will shrinks or swells depending on the solute concentration of the cell in relation to the solute concentration of the fluid surrounding the cell (1). It follows that water will move from a region of high water concentration to a region of low water concentration therefore‚ if a cell is placed in a hypertonic solution water will move from the cell into the solution until the

Investigation of Factors Affect Osmosis in Potatoes Aim The aim of the following experiment was to investigate the effect of varying the concentration of sucrose solution on osmosis in a potato. Preliminary Experiments One preliminary experiment was done before the main experiment. From the preliminary‚ we were trying to find out how osmosis actually occurred in potatoes‚ and gave us a vague idea on what the main experiment would be like. This preliminary will aid my prediction

Tissue engineering By Nathan. F Introduction Tissue Engineering is the use of a combination of cells‚ engineering and materials methods‚ and suitable biochemical and physio-chemical factors to improve or replace biochemical functions. The objective of tissue engineering is to create living body parts that will fully integrate with the recipient’s body. Tissue engineering mostly associated with applications that repair or replace portions of or whole tissues. For example bone‚ cartilage

Epithelial tissue Covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection‚ secretion‚ absorption‚ and filtration. The skin is an organ made up of epithelial tissue which protects the body from dirt‚ dust‚ bacteria and other microbes that may be harmful. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the

Histology This lab focused on the examination and identification of tissues that make up the organs of the body. The tissues are divided into four main categories: epithelial‚ connective‚ muscle‚ and neuronal. Click on the thumbnail images to see a larger version. All of the photomicrographs were taken using the 40X objective (400X magnification)‚ which is the highest magnification we use in this lab. Other resources include linked web pages on the "Resources" page and the histology tutorial

There are four types of tissue found in animals: connective‚ muscle‚ nervous‚ and epithelial. We are going to go into muscle tissue. The cells of muscle tissues are called fibers. There are three types of muscle tissue and they are skeletal‚ cardiac‚ and smooth. All types can go though hypertrophy (enlargement or overgrowth of an organ or part of the body due to the increased size of the constituent cells). Muscle fibers contract due to the interaction of the contractile proteins‚ actin and myosin

There are three different types of epithelial tissues that are found inside the human body. There is the cutaneous membrane (tissue)‚ which we would refer to as “skin”. This part is the only epithelial tissue that is touched by air and is dry. The cutaneous membrane is composed of keratinizing stratified squamous epithelium. The second is the mucous membrane‚ which is the tissue used for absorption and secretion‚ protective lubricating mucus in the repertory and digestive system. This membrane

Types of Tissues Stacy Sisler HS 120‚ Section 03 Unit 2 Seminar Kaplan University Jan. 17‚ 2011 Types of Tissue A tissue is a group of cells that have a similar shape and function. Different type of tissues can be found in different organs. In humans‚ there re four basic types of tissue: epithelial tissue‚ connective tissue‚ muscular tissue‚ and nervous tissue. There may be various sub-tissues within each of the primary tissues. Epithelial tissue covers the body
