    The cell membrane is made up of fats‚ proteins‚ lipids‚ and carbohydrates‚ and is a permeable structure. However‚ this permeation is very discerning because it only lets certain things pass through it. The cell membrane has a layer of phospholipids with hydrophobic ends and hydrophilic tops. The “tails” are made out of phosphate‚ while the “heads” are made up of two strings of fatty acids. There are two layers of these phospholipids‚ called the “bilayer”‚ and the tips of each phospholipid are facing

    INTRODUCTION Osmosis is the movement of water molecules from high concentration to low concentration through semipermeable membranes‚ caused by the difference in concentrations on the two sides of a membrane (Rbowen‚ L.). It occurs in both animals and plants cells. In human bodies‚ the process of osmosis is primarily found in the kidneys‚ in the glomerulus. In plants‚ osmosis is carried out everywhere within the cells of the plant (World Book‚ 1997). This can be shown by an experiment with potato

    bacteria’s contents intact. The Cell Membrane: Is a phospholipid bilayer that completely surrounds a bacterial cell. Cell membrane acts as a highly selective barrier. This barrier prevents materials from diffusing into and out of the cell. This allows the cell to take up chemicals and nutrients needed for survival while keeping the cell components separated from the environment. The fluid and all its dissolved or suspended particles that can be found within a bacterial cell are called the Cytoplasm.

    Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in

    find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration is called

    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

    Ethanol Ethanol is easily soluble in water in all proportions with a slight overall decrease in volume when the two are mixed. Absolute ethanol and 95% ethanol are themselves good solvents‚ somewhat less polar than water and used in perfumes‚ paints and tinctures. Other proportions of ethanol with water or other solvents can also be used as a solvent. Alcoholic drinks have a large variety of tastes because various flavor compounds are dissolved during brewing. When ethanol is produced as a mixing

    Luke Fancy Pro/Con Paper: Pros of Ethanol Due: 12/07/11 Ethanol was first used in 1908 on Henry Ford’s Model T. The Model T was designed so that it could be run on either gasoline or pure alcohol. When asked why he wanted to run the Model T on alcohol‚ Henry Ford replied by saying‚ “It is the fuel of the future.” The use of ethanol continued through the 1920’s and 1930’s in an effort to keep a United States ethanol program alive. Although the effort was unsuccessful‚ oil supply problems
