Study 12 Photosynthesis #3 (Oxygen Production) flashcards from Mark R. on StudyBlue. In this experiment (Figure 9.2), we will study the effect of light intensity on the photosynthetic activity of Elodea canadensis.We will vary the light intensity by changing the distance between the light source and the plant. The aim of the experiment: To prove that oxygen is evolved in green plants during photosynthesis. Oxygen gas (O 2) is a byproduct of this reaction. One common way is to gather bubbles of gas given off by an aquatic plant. Demonstrating oxygen formation during photosynthesis can be a tricky process. It is employed by plants, algae and certain bacteria. The equation for photosynthesis can be written as follows: 6CO 2 + 6H 2 O + light energy → C 6 H 12 O 6 + 6O 2. Here use Hydrilla plants. How might the tank hinder the lab? Using synthetic compound Nafion, Splitting water will be converted into oxygen and hydrogen. Science behind the experiment. The production of oxygen by photosynthesis is most easily seen in water plants such as Elodea and Cabomba. The conditions that I set in the lab are the intensity of light, the temperature, Carbon Dioxide levels, Color, and the wavelength of light. You have learned that photosynthesis involves the conversion of carbon dioxide and water into organic molecules such as glucose. Leaves take in carbon dioxide and through the process of photosynthesis they create food for the plant. It provides the basis for life on Earth and is the ultimate source of all fossil fuels and of the oxygen we breathe. Write 2-3 sentences conclusion with explanation in terms of the process of photosynthesis. The bubbles you observed on the leaf and sides of the glass were oxygen. Photosynthesis is the biological process that converts sunlight into chemical energy. ... We did not want heat to be a variable in the experiment. We will count the emerging oxygen bubbles as … These plants can bring out photosynthesis even they are surrounded by water. In the first experiment, we will be using the same plant you examined in Lab 3 called Elodea. This teaching resource introduces Cabomba, a pondweed which is much more effective than the traditional Elodea. Study 12 Photosynthesis #3 (Oxygen Production) flashcards from Mark R. on StudyBlue. This experiment is a continuation of the experiment "Oxygen Production in Elodea in Direct Light, Distant Light, and Darkness.Temperatures under 15C will not affect oxygen production in photosynthesis yet temperature over 40C will greatly increase oxygen production. 9. Experiment to show that oxygen is produced during photosynthesis - definition To prove that oxygen is produced during photosynthesis following steps need to do Place water plant in … Oxygen Release in Photosynthesis Protocol. As seen in the graph, when the temperature reaches a certain level, the rate of oxygen production begins to decline. The production of oxygen is used to measure the rate of photosynthesis as oxygen is a byproduct of this process. Oxygen production by photosynthetic organisms explains why earth has an oxygen-rich atmosphere. This shows that the rate of photosynthesis and oxygen production increases as the temperature increases but declines after the temperature reaches around 25 degrees Celcius. In doing so, oxygen is a product while carbon dioxide is a reactant that is used up during photosynthesis. Oxygen is a by product of this and goes into the air. In the leaf-disk assay, all of the components necessary for photosynthesis are present. Still, the alternative hypothesis which was light is a necessity in the production of oxygen during photosynthesis was supported. The we breathe contains 21% oxygen produced by plants. Introduction.
