in order for a plant to grow and survive it has to carry out photosynthesis this process takes place in the leaves and more specifically the subcellular structures called chloroplasts within these structures is a pigment called chlorophyll that can absorb light which you can think of as little packets of energy and it uses this energy to convert carbon dioxide and water into glucose and oxygen we can also write this equation using chemical symbols where we'd have six co2 molecules combining with six h2o molecules to make a single molecule of glucose and in doing so also give out six o2 molecules notice that we've written light on top of the reaction line here that's because the reaction requires light energy for it to take place whenever energy from the surroundings is used to help a reaction take place like this we call it an endothermic reaction and in this case we could say that energy is transferred from the environment to chloroplasts by light we've already looked
