    Assignment 1: Cell Membranes and Temperature Background Theory Beetroot contains betalain pigments within it’s vacuole‚ which gives it it’s purple-red colour‚ it’s this pigment which leaks out as the beetroot is heated and the cells membrane begins to break down. The practicals aim is to show the effect of temperature on the cell membrane by observing the colour change of the water the beetroot was placed in. The cell membrane is important as it controls the substances enters and leaves the cell with

    Experiment 2 The Cell Membrane Abstract The boundary between any cell and its environment is the plasma membrane‚ composed of a matrix of phospholipid molecules along with a number of different kinds of proteins. Membranes have different properties and a variety of functions‚ in large part determined by the specific proteins within the membrane. This experiment is designed to determine the stress that various factors‚ such as osmotic balance‚ detergents and pH‚ have on biological membranes. There are

    Cell Membrane Structure Phospholipids are arranged in to layers‚ called the bilayer. They only have 2 fatty acids‚ this is because the third fatty acid is replaced by a negatively charged phosphate group. The phosphate heads are polar‚ in other words attracted to water‚ therefore they are hydrophilic. The lipid tails are non-popular as they’re not attracted to water and therefore known as hydrophobic. When phospholipids are added to the water‚ they rearrange themselves so that the hydrophilic heads

    century‚ little was known about cell membranes. Until the early 1950s‚ the biological cell membrane was rarely mentioned in scientific literature. It was recognised that something was probably there‚ but hardly anything about it was known. Considering the lack of technical equipment available a century ago‚ scientists such as Charles Overton and Edwin Gorter were not only exploring new territory in looking at the properties of cell membranes‚ but laying the way for future cell biologists. Scientists had

    Cell Membrane The Cell Membrane- The cell membrane is a semi-permeable membrane that surrounds the cytoplasm of a cell; the cell membrane is made up of phospholipids‚ proteins and carbohydrates. Its function is to protect the integrity of the interior of the cell allowing certain substances into the cell‚ while keeping other substances out. The phospholipids form a thin‚ flexible sheet while the proteins float in the phospholipid sheet like an ice berg‚ and the carbohydrates extend out from the

    Cell Membrane Transport The purposes for these experiments is to be able to understand osmosis and its relationship to tonicity of solutions‚ and the transportation of molecules across cell membranes. It’s also used to understand‚ and how temperature affects diffusion. You also learn how to test for presences of starches and sugars in solutions. In the first exercise I will be testing for diffusion through an artificial membranes. This one has forty five steps to it. I will not go into

    ’direct ’ passage in and out of the plasma membrane ( Lacerda L.2011) Allowing some molecules enter and exit the cell membrane‚ to create a balance in concentration inside and outside of the cell‚ by doing so the cell often become hypotonic‚ where the concentration outside the cell is higher than the concentration inside the cell‚ therefore causing the swelling of that cell. When cell was placed the the deionized water environment‚ hypothesis was made that the cell will become hypotonic and swell up as
