Photosynthesis & Fermentation Plant Cellular Metabolism Report

The practical was carried out to investigate the various forms of plant cell metabolism. The process of photosynthesis and fermentation was the main focus of the practical exercise. The first practice was on photosynthesis (the hill reaction) and variations in light intensity, light wavelength and inhibiting substances were investigated. The second practical focused on starch synthesis “the Dark reaction,” this is the light-independent stage of photosynthesis. In this experiment, the conversion of sugars to starch for storage is shown in the third experiment, fermentation was studied using fresh and boiled potato extracts and the yeast cell (Saccaromyces cerevisiae). The role of the fermentation process to provide energy for the yeast cells is shown in this experiment. The results were tabulated, analysed and discussed to understand the practical.
