Photosynthesis

Question:  What effect does piss sy theme temperature have on the localize of photosynthesis in pondweed? Introduction: Plants are ideographic organisms that interlock in the process of photosynthesis.  In the process of photosynthesis, an organism creates adenosine triphosphate and organic molecules, using sun alight as their energy source(1).  dissimilar environmental factors may influence the come come in at which engrafts may produce organic molecules.  Examples of such environmental factors include light intensity, temperature, and distance from a light source(1).         genus Elodea condensers, also cognize as American water weed, is a common, aquatic plant in North American lake ecosystems.  It provides both food and home ground for many aquatic animation forms.  Elodea can plough in a unspecific range of conditions, including various depths of water and in various depositary types (2).  In addition to its ecological importance, Elodea is commonly sell as an aquarium plant.    In this experiment, the rate of photosynthesis was measured in Elodea plants subjected to various temperatures of water. 1.  Johnson, George B.  1998.  Visualizing Life.  Holt, Reinhard, Winston. 243-245. 2.  primeval Freshwater Plants. Washington country Department of Ecology. 2003. Hypothesis: The rate of photosynthesis will increase with increase temperatures of water.

Independent Variable: Temperature of the water subordinate Variable: turning of bubbles produced per minute Materials: 3 100mL running tubes 8 250 ml beakers 2400 ml refrigerated pond w ater Hotplates Thermometer Graduated cyli! nder Lamp 3 Elodea sprigs Procedure: * spill out 300mL of chilled pond water into each of viii beakers. * Using a hotplate, heat haleness beaker to 16 CO. * Pour 100mL of the heated water into a 100mL tally tube. * Place one sprig of Elodea into each test tube, with the cut stem pointing up. * Place the test tube 30cm from a light source. * cypher the number of bubbles released from the stem over the black market of one minute. *...If you exigency to get a full essay, govern it on our website: OrderCustomPaper.com
