Question: What effect does water system 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 vital force source(1). dissimilar environmental factors may influence the come prohibited at which engrafts may produce organic molecules. Examples of such environmental factors include light intensity, temperature, and distance from a light source(1).        ditchmoss 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 deportment forms. Elodea can plough in a round-eyed range of conditions, including various depths of water and in various depositary types (2). In addition to its ecolo gical 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.
