production of oxygen in photosynthesis experiment

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