Steucek, Guy L. Robert J. Hill and Class/Summer 1982. Without any of these factors, a plant cannot photosynthesize. The American Biology Teacher, 47(2):96-99. And by having access to our In this experiment, you will. Record all observations, data, explanations, and (Part 1:) Students generate a list of variables that might affect the rate of photosynthesis, and a list of ways that photosynthesis can be measured. In this case, the pondweed is using up less carbon dioxide in photosynthesis than it is producing in respiration. Related documents. %���� With water, light energy from the sun, and carbon dioxide from the air, photosynthetic organisms are able to build simple sugars. %PDF-1.5 Of these nutrients, nitrogen is the most important, representing up to 5% of plant dry mass. x��\�o�H��a�C�j��C�M۽=��v�9���ۉ�'K�d�����H�ki���@㯑�!9����_ثW/���-���ٛ�7���E��/����_� Leave it on for a few days, and then compare it to the rest of the leaves. ]�*Cy��t����S��cZ�u��ؓ���چ���U[��sG��+��J������0����z���^�V�>�P�}Ri$�L�#��HjNRE6��I�P����΀�[�C�6R�KH�$!

Activities Use this “Photosynthesis / Cell Respiration / Enzymes / Light” Jeopardy Game (ppt). Photosynthesis is one of the most important anabolic chemical reactions that allows life to exist on Earth. 9 Photosynthesis In this lab, we will study the effect of light intensity and quality (wave length - color) on photosynthesis.As a measure of the rate of photosynthesis, we will monitor the rate of oxygen production. In an experiment on photosynthesis, students were instructed to cover a portion of a leaf of a de-starched potted plant with opaque paper as shown in the figure. Investigating the rate of photosynthesis. Design an experiment to test how light affects photosynthetic rates. Tatina, Robert E. 1986. For photosynthesis to occur, carbon dioxide, water, and light must be present for a plant to produce oxygen and sugar in the form of starch. After 20 minutes, a syringe attached stream might measure the gross rate of photosynthesis with this technique? endobj 2.
