Aim In this investigation is to see is to see if when there is more light shining onto some pondweed in sodium carbonate solution it affects the amount of bubbles produced from the pondweed. Background information Photosynthesis is a chemical reaction occurring in the leaves of green plants. Using the energy from sunlight, it changes carbon dioxide and water into glucose and oxygen. Certain things will limit photosynthesis from photosynthesising quickly. One of these things is light. A plant can have lots of carbon dioxide and water but if it doesn't have enough light it won't work. Equation for Photosynthesis Carbon Dioxide + Water + Light Energy ==> Glucose + Oxygen Balanced Equation for Photosynthesis 6CO2+ 6H20 + Light energy ==> (chlorophyll) ==> C6H12O6+ 6O For photosynthesis to take place a plant must have enough Carbon Dioxide, Water and Light. When photosynthesis occurs Glucose and...
