Light energy is needed for photosynthesis to happen. 5 of 10 he waste by-product of photosynthesis is: Oxygen is a waste by-product of photosynthesis. Carbon dioxide is needed for photosynthesis. 6 of 10 Tomatoes in a greenhouse grow faster if the carbon dioxide concentration is increased. This shows that: Carbon dioxide concentration must have been a limiting factor if the rate of photosynthesis increased with more of the gas. 7 of 10 Photosynthesis can be summarised by which word equation? he word equation that summarises photosynthesis is: carbon dioxide + water → glucose + oxygen. 8 of 10 Why do plants need nitrate ions?
