Light Absorption by Photosynthetic Pigments in Silver Beet Abstract The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a‚ chlorophyll b‚ and carotene via chromatographs. Chlorophylls were then separated and an absorption spectra created using results obtained from a spectrophotometer. It was clear there were two distinct peaks

The Silver Maple (Acer Saccharinum) samaras reside in the eastern United States and undergo seed dispersal between April and July of each year. During seed dispersal these fruits are trying to disperse their seeds as far away from their tree as possible to have the highest success to produce offspring. The seeds that disperse close to the parent plant have shown less success and higher mortality rates than seeds that disperse farther from the base of the tree. Also‚ fruits with larger seeds have

Effect of light on Silver Halide Salts Aim: To investigate the effect of sunlight and UV light on silver salts and to identify an application of this reaction. Hypothesis: The compounds exposed to sunlight (which already contains UV light) will decompose. The compounds which are not exposed to light (put in a dark place) will not decompose. Theory: Equipment: * 4 x petri dishes * 1 x glass stirring rod * 0.1 mol/L silver nitrate in a dropper bottle * 0.1 mol/L Sodium chloride
