We know that the food plants made from photosynthesis are called CARBOHYDRATES. Carbohydrates contain the atoms CARBON, HYDROGEN and OXYGEN. The carbohydrate shown above is called glucose. Which part of the word “carbohydrate” suggests that it contains carbon? Which part suggests that it contains hydrogen? What does “ate” mean, do you think? Count the atoms – how could we write the formula for glucose? During photosynthesis what molecules does a plant use? What molecules does it produce? Can you write the word equation for photosynthesis? Can you write a symbol equation? Can you balance it?
