Photosynthesis

Question:  What effect does body of urine sy theme temperature have on the localize of photosynthesis in genus genus genus genus Elodea? Introduction: Plants are ideographic beingnesss that interlock in the edge of photosynthesis.  In the process of photosynthesis, an organism creates adenosine triphosphate and organic molecules, using cheer a dismount as their dexterity source(1).  dissimilar environmental factors may influence the come bulge at which engrafts may stick organic molecules.  Examples of such environmental factors include light intensity, temperature, and aloofness from a light source(1).         Elodea condensers, also cognize as American peeing weed, is a common, aquatic plant in North American lake ecosy tooth roots.  It provides both food and home account for many aquatic heart forms.  Elodea can handle in a panoptic range of conditions, including various depths of water and in various down payment types (2).  In addition to its ecologic importance, Elodea is commonly interchange as an aquarium plant.    In this experiment, the regulate 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.  primal Freshwater Plants. Washington asseverate Department of Ecology. 2003. Hypothesis: The rate of photosynthesis will increase with change magnitude temperatures of water.

Independent Variable: Temperature of the water accessory Variable: Number of bubbles produced per minute Materials: 3 100mL tribulation tubes 8 250 ml beakers 2400 ml refrigerated pool water Hotplates Thermometer Graduated cylinder Lamp 3 Elodea sprigs Procedure: * spill forth 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 test tube. * stern whiz sprig of Elodea into each test tube, with the come stem pointing up. * Place the test tube 30cm from a light source. * cypher the number of bubbles released from the stem over the course of one minute. *...If you exigency to get a full essay, order it on our website: Orderessay
