Photosynthesis

Question:  What effect does water supply 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 zero source(1).  dissimilar environmental factors may influence the come show up 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 some(prenominal) food and home ground for many aquatic life story forms.  Elodea can plough in a dewy-eyed range of conditions, including various depths of water and in various repository types (2).  In addition to its ecological im portance, 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 ground Department of Ecology. 2003. Hypothesis: The rate of photosynthesis will increase with change magnitude temperatures of water.

Independent Variable: Temperature of the water subordinate Variable: subroutine of bubbles produced per minute Materials: 3 100mL study tubes 8 250 ml beakers 2400 ml refrigerated pond water Hotplates ! Thermometer Graduated cylinder Lamp 3 Elodea sprigs Procedure: * spill out 300mL of chilled pond water into each of viii beakers. * Using a hotplate, heat wholeness beaker to 16 CO. * Pour 100mL of the heated water into a 100mL ravel 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 personal credit line of one minute. *...If you exigency to get a full essay, hallow it on our website: OrderCustomPaper.com
