Human: Help me to understand the process of photosynthesis. Assistant: 
Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the sun, into chemical energy that can be used to fuel the organisms' activities. During photosynthesis, carbon dioxide and water are taken in from the environment and converted into oxygen and glucose (sugar). This process also releases the chemical energy stored in the glucose which the organism can then use for other life functions. The overall equation for photosynthesis is: carbon dioxide + water + light energy --> oxygen + glucose.
