Life on earth is dependent on photosynthesis for what two things? The stomata are pores in the leaf through which much water is lost to the atmosphere. Chlorophyll absorbs a photon of light, becomes excited and donates an activated electron to the reaction center. If they are photosynthetic, they use the light energy from the sun to produce food in the form of glucose. Chloroplasts contain a light absorbing molecule called chlorophyll and this is the place in plants where photosynthesis takes place.
