Design an experiment to study the payoff of an abiotic factor on any vegetation process in an aquatic coif mark: To study the effect of conflag array 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 degree Celsius dioxide and weewee in the presence of chlorophyll and light energy. there are deuce-ace common environmental factors which affect the estimate 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 cosmos 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 federal agency of light medullas (10W, 20W, 30W etc) Dependent- The rate of photosynthesis is based on the amount of bubbles minded(p) come in per minute. Controlled- The plant, Carbon dioxide, Temperature, Source of water, Fertilizer Methods to witness variables: 1) Carbon dioxide is controlled by adding 1 gram of Sodium hydroxide in each beaker. 2) The plant should be same for on the whole 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 flaskful of 500ml each, 5cm branches of Hydrilla plant, light electric-light bulbs of 10,20,30 and 40 watts, spatter syringe , step ta pe, scissors. Diagram: Procedure: -Fi! ll 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 respective flask - Using the measuring tape, measure 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
