Design an experiment to study the set of an abiotic factor on any vegetation process in an aquatic imbed mark: To study the effect of conflag score intensity on the tell of photosynthesis of an aquatic plant. Background: Photosynthesis is an important activity of completely in all squirt plants. They are able to synthesize food from nose candy dioxide and weewee in the presence of chlorophyll and light energy. on that point are leash common environmental factors which affect the put 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 world 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 advocator of light medullas (10W, 20W, 30W etc) Dependent- The rate of phot osynthesis 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 comptroller variables: 1) Carbon dioxide is controlled by adding 1 gram of Sodium hydrated oxide in separately beaker. 2) The plant should be same for all 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 medullas of 10,20,30 and 40 watts, spatter syringe , step tape, scissors . Diagram: Procedure: -Fill three con! ical 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
