Rate of Photosynthesis Planning Introduction Photosynthesis is the process whereby plants and certain photoautotroph make food using carbon dioxide and water. When both (carbon dioxide and water) are combined, they make the food; glucose as well as oxygen, given off as a by-product. The above description of photosynthesis can be analysed in the equation below: BALANCED CHEMICAL EQUATION 6CO2 + 6H2O=C6H12O6 + 6O2 WORD EQUATION Carbon Dioxide + Water=Glucose + Oxygen Factors that affect photosynthesis: LIGHT: insufficient light slows down the rate of photosynthesis CARBON DIOXIDE: similarly, inadequate quantity of carbon dioxide slows down the rate of photosynthesis. TEMPERATURE: temperature should not be too cold nor too hot. Aim My aim is to investigate whether the factor 'light', has an affect on the rate of photosynthesis. This will be observed by counting the number of oxygen bubbles given off. Apparatus * Metre rule * 5cm Canadian pondweed clipped on a paperclip * Beaker * Lamp, with 60 watts bulb * Water Hypothesis It is predicted that, the more light intensity the...
