Biology course work Aim: effect of different light intensity on the amount of oxygen produced by pondweeds. Introduction: Oxygenating plants can obtain the energy for synthesis directly from the sun's radiation. It is then used to build up essential organic compounds from inorganic molecules. Such organisms are called photosynthetic and possess special pigments, which can absorb the necessary light energy. Photosynthesis is the source of energy and organic materials for other organisms besides plants. So it can be seen that the ultimate source of all metabolic energy is the sun and photosynthesis is responsible for the maintenance of life on earth. Photosynthesis in green plants is the process in which energy from the sun is transformed in to chemical bond energy in organic molecules. It is a process in which energy is transduced from one form to another and results in the inorganic molecules, carbon dioxide and water,...
