Investigating Photosynthesis Aims: The aim of our investigation is to find out how the amount of light, that is light intensity, affects the rate of photosynthesis. Background information: What variables are involved. Dependant variable: Light intensity, distance, lamp and plant. Key factors to control: * temperature * number of leaves * presence of chlorophyll * time Preliminary practical work: Carbon dioxide + water glucose + oxygen Light and chlorophyll 6CO + 6H O C H O + 60 * Photosynthesis is when green plants produce glucose from sunlight. * Light energy, water, chlorophyll, glucose and carbon dioxide are needed for photosynthesis to take place. * Sunlight, chlorophyll, water and carbon dioxide are needed during photosynthesis. * Sodium hydrogencarbonate increases the levels of carbon dioxide in a plant. * It does matter if all the leaves are of different sizes because then the experiment will not be fair and therefore results will not be reliable. * We can assume that each leaf is approximately the...
