A. PHOTOSYNTHESIS Photosynthesis n: A process by which green plants and other organisms produce simple carbohydrates from carbon dioxide and hydrogen, using energy that chlorophyll or other organic cellular pigments absorb from radiant sources.
  Photosynthesis is a process used by plants, which is done to make food (glucose/sugar).   Photosynthesis requires carbon dioxide (CO2), sunlight, and water (H2O) whic â¦ h would create glucose (sugar), and oxygen (O2).   A compound is a group of 2 or more different atoms combined chemically.  The compounds that is included for photosynthesis is carbon dioxide and water. 6 people found this useful.
