Stesha Britman November 7, 2007 Biology Lab Rate of Photosynthesis Abstract: In this lab, our purpose is to see if the quantity of light affects the plant cells capability to execute photosynthesis. I predict that photosynthesis will perform more adequately being in sunlight but the plant doesn’t need to be in direct light in order to perform. I will place a sprig of Elodea in a test tube of water and baking powder. Then see if it produces more bubbles in dim light or bright light. I found that the plant produced more bubbles in bright light. My hypothesis was correct because the more light energy provided means the more chemical energy produced to perform photosynthesis. I learned that you should put you plants in direct sunlight to get the best growth. Introduction: Photosynthesis is the process by which plants and other organisms, such as photosynthetic algae and bacteria, take light energy and convert it into chemical energy in the form of carbohydrates. Photosynthesis occurs in the chloroplast of the cell which contains the organelle chlorophyll. Chlorophyll absorbs the energy of sunlight. That light energy is converted to chemical energy through the steps of photosynthesis. The reactions of photosynthesis are divided into light-dependent reactions and light-
