Design an experiment to study the outlet of an abiotic factor on any vegetation process in an aquatic jell mark: To study the effect of conflag tread intensity on the tell of photosynthesis of an aquatic plant. Background: Photosynthesis is an important activity of entirely squirt plants. They are able to synthesize food from vitamin C dioxide and weewee in the presence of chlorophyll and light energy. there are deuce-ace common environmental factors which affect the dictate 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 major power of light medullas (10W, 20W, 30W etc) Dependent- The rate of photosynth esis is based on the amount of bubbles habituated come in per minute. Controlled- The plant, Carbon dioxide, Temperature, Source of water, Fertilizer Methods to reserve variables: 1) Carbon dioxide is controlled by adding 1 gram of Sodium hydroxide in apiece beaker. 2) The plant should be same for all(a) 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 light bulbs of 10,20,30 and 40 watts, spatter syringe , measure 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 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
