Biology Experiment Absorbance of Beet Root Sarah Hsu Y 11 Hope Purpose The beetroot experiment is to investigate and understand the affect different temperatures have on cell membrane structures. Hypothesis The higher the temperature is‚ the higher the rate of absorbance of the cell membrane will be. Variables Controlled Variables | Independent Variables | Dependent Variables | The length of the beetroot placed into the test tube. | The temperature of the water bath. | The absorbance

predict that as the temperature is raised the number of molecules that are able to leave the cell and come into the solution will increase‚ however I think that there will be appoint at which the amount of molecules coming out will remain constant. Red beet tissue contains large amounts of betacyanin‚ a red pigment‚ located in the large internal membrane vacuoles. When the membrane is damaged‚ the pigment can cross the vacuole membrane and cell membrane. Since pigment is water soluble and not lipid soluble

The Effect of Temperature on Beet Cell Membranes and Concentration of Betacyanin Released Introduction Membranes are an important feature of plant cells and they act as a barrier that separates the interior of the cell from the external environment (Campbell et al.‚ 2008). Each membrane layer is composed of a phospholipid layer‚ which is semi-permeable and possesses the ability to control the movement of diffusion. Within the centre of a cell‚ the vacuole that is responsible for storage and

Sea level Global warming is effecting the Bahamas by raising the sea levels of the ocean‚ which will cause there to be less land that actually makes up the Bahamas. This can actually make all of the Bahamas a smaller country because more land is being put under water to the rising sea level‚ Warmer ocean temperatures are also now understood to cause coral bleaching. Rising levels of carbon dioxide (greenhouse gas emissions) are also decreasing the pH level of the ocean‚ known as ocean acidification

The Effect of Temperature on Beet Cell Membranes Introduction In this lab‚ we are going to learn how the stress of temperature affects fresh beets. We have come to learn that cell membranes organize the chemical activities of cells. All cells are made of plasma membranes‚ often called fluid mosaics. It is sometimes described as a mosaic because it is made of protein molecules that are embedded into phospholipids. Phospholipids are the main structural support of the membrane and the proteins
