Design an experiment to study the center of an abiotic factor on any vegetation process in an aquatic whole kit and boodle mark: To study the effect of conflag pass judgment intensity on the tell of photosynthesis of an aquatic plant. Background: Photosynthesis is an important activity of completely squirt plants. They are able to synthesize food from atomic number 6 dioxide and weewee in the presence of chlorophyll and light energy. in that respect are troika common environmental factors which affect the say of this reply; these are the effect of ever-changing light intensity, the effect of changing temperature, and the effect of changing the carbon dioxide concentration. The factor being looked at for this experiment is the changing light intensity. Hypothesis: The rate of photosynthesis increases as the intensity of light increases. Variables: Independent- The amount of light provided to the plants. The cause of light medullas (10W, 20W, 30W etc) Depend ent- The rate of photosynthesis is based on the amount of bubbles given up come in per minute. Controlled- The plant, Carbon dioxide, Temperature, Source of water, Fertilizer Methods to arrest variables: 1) Carbon dioxide is controlled by adding 1 gram of Sodium hydrated oxide in to each one beaker. 2) The plant should be same for every last(predicate) the beakers. 3) The room temperature should be constant 4) The microbe of water should be same for all the beakers. Apparatus: one-third cone-shaped flask of 500ml each, 5cm branches of Hydrilla plant, light electric lights of 10,20,30 and 40 watts, spatter syringe , criterion tape, scissors. Diagram: Procedure: -Fill three conical flasks with 500ml of water each (water from the same source with the same temperature this improves the experiments validity); hence label them A, B, and C - Then, cut bring out three branches of the plant (using scissors) of three centimeters, and place them each in a res pective flask - Using the measuring tape, m! easure 10 centimeters away from flask A and place the 10W light bulb here. - Place a gas syringe on this flask and turn...If you want to get a full essay, order it on our website: OrderCustomPaper.com
