THE BASIC NEEDS FOR PHOTOSYNTHESIS Plants, as well as some Protists and Monerans, can take small molecules from the environment and bind them together using the energy of light. The incoming light energy is transformed into the energy holding the new molecules together, and the organisms use those molecules as an energy "fuel." The basic process can be represented this way: CO2 + H2O light> C6H12O6 + O2 Carbon Dioxide Water (sugar) Oxygen In the case of water organisms, the carbon dioxide and water are from their immediate surroundings; for most land plants, the water is absorbed from the soil and the carbon dioxide from the atmosphere. The glucose is used for two major purposes: 1) it serves as an energy reserve for periods of darkness (don't forget that photosynthesizers, like any living things, require energy and get it through respiration processes, commonly aerobic respiration, and 2) it is used as a major...
