Photosynthesis

Question:  What effect does peeing sy theme temperature have on the localize of photosynthesis in pondweed? Introduction: Plants are ideographic beingnesss 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 cypher source(1).  dissimilar environmental factors may influence the come appear 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(prenominal) food and home ground for many aquatic life-time forms.  Elodea can plough in a coarse range of conditions, including various depths of water and in various repository types (2).  In addition to its ecological importanc e, 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 demesne Department of Ecology. 2003. Hypothesis: The rate of photosynthesis will increase with increase temperatures of water.
