LIGHT INTENSITY AND PHOTOSYNTHESIS LAB REPORT GROUP MEMBERS: MARITONI VALENCIA, SANGITA TAMANG, RYUTARO SEIKI AND MAO INTRODUCTION: Light intensity is one of the factors affecting the rate of photosynthesis.Other factors are concentration of carbon dioxide, temperature and to a lesser degree, … Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. Using the following virtual simulation created by the University of Reading in partnership with Syngenta, you will observe and measure the rate of photosynthesis of Elodea - a It's quite easy with Elodea! Different colors of light effect the speed of photosynthesis. The punched out leaf disks will initially sink in a test tube of water but will float as photosynthesis occurs. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Tweet. There are a few key methods to calculate the rate of photosynthesis. Procedure A. Introductory Biology I (BIO 110) Academic year. Comments. Your answers will be recorded on paper, not electronically. Effect of light intensity on rate of photosynthesis on elodea plant. The test tube was then put under a light, covered by a green filter. This allows the students to focus on only one process -- either photosynthesis or respiration. Share. Course. Objective: To measure the rate of photosynthesis at varying light intensities. Elodea Photosynthesis Lab Science Project Education Com. Lab 11: Photosynthesis. Measuring the Rate of Photosynthesis of Elodea . What gases are produced by plants during photosynthesis? The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min). Background Information: Without photosynthesis, life as we know it would not exist. Read the directions on the paper before starting. A post-lab class discussion would include the sharing of information between the two groups. Place the sprig in a test tube, cut side up. Photosynthesis Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide, affected the rate of photosynthesis. Add water to test tube and a pinch of baking soda. After that point, the rise in carbon dioxide levels has no effect on the rate of photosynthesis.
