effect of carbon dioxide on rate of photosynthesis

... Planning of photosynthesis investigation Aim: The aim of this experiment is to investigate into the effects of the change of carbon dioxide concentrations on the rate of photosynthesis. Prediction: My hypothesis is that as the concentration of carbon dioxide increases the rate of photosynthesis will also increase. Graph showing the effects of carbon dioxide on the rate of photosynthesis Light intensity Scientific reasoning: Photosynthesis is the process by which chlorophyll containing organisms capture energy in the form of light and convert it to chemical energy. Plants make food through a process called photosynthesis. Using energy from the sun, cells in the leaves turn simple materials into energy rich food. Spongy cells are partly surrounded with pockets of air, which enable the cells to exchange gases with the atmosphere. The stomata are small openings in the lower epidermis under the leaf. Carbon dioxide enters through the stomata. Carbon dioxide combines with water and is photosynthesised into oxygen and
