increase the permeability of the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim of this practical is to use beetroot to examine the effect of temperature on cell membranes and relate

liquid permeability of porous media. The apparatus used in the experiment is the liquid permeameter. The liquid used in this experiment is water. Three membrane samples of different thickness (0.1‚ 0.2‚ 0.3 cm) are used as the porous media. The determination of the permeability is carried out using elevated pressure test. Each sample is tested for 5 times at different values of pressure gradient which are 5‚ 10‚ 15‚ 20 and 30 psi. In order to obtain more accurate data‚ ensure that the membrane samples

Title: to get organic food Specific purpose: Organic food advocates claim that organically grown foods are safer and more nutritious than foods raised with non-organic methods such as pesticide and non-organic fertilizer use‚ or antibiotic and hormone use. Thesis statement: Many people just don’t trust these chemicals and don’t want to put them into their bodies. Since virtually all non-organically produced foods contain residues of pesticides‚ fertilizers and other chemicals‚ the only way to

Chemistry Department Speaker on Solar Cells — Outside event October 24‚ 2017 Today I attended a talk curated by the Ithaca College Chemistry Department by Kathleen Sampson‚ a Ph.D. Candidate at the University of Toronto. Sampson presented about the intersections of chemistry and engineering in regards to innovating new materials to produce solar energy. Sampson discussed organic solar cells‚ a type of solar energy technology that converts sunlight into electricity using “Earth-abundant‚ carbon-based

Biology Lab Report - Movement in and out of cells (4A) Shiang Chen Ting (24) Sec 313 Introduction The aim of this experiment is to explore the factors which affect the movement of materials in and out of the cells. The dark red or purple colour of Beetroots is caused by a pigment called betalain that is found within the vacuole of the beetroot cells. The pigment remains intact within the cell if the cells are not “stressed” by the external environment. In this exploration‚ two factors that affect
