““We know a great deal more than the Greeks did about the forces of life. But with all our knowledge, no one fully comprehends the miraculous process, known as photosynthesis, by which trees and other green plants use energy from the sun to transform elements into food for themselves at the same time that they release oxygen into the atmosphere. Photosynthesis makes life on Earth possible, and it is the most important function performed by green plants of all kinds.””
