Photosynthesis

Dust jacket "In his customary lucid and engaging style, Isaac Asimov provides a look through the chemist's eyes at the process upon which life in all its forms is utterly dependent. Why is it that the earth's food supply doesn't run out? What is responsible fro the replenishment of the atmosphere's store of oxygen? How is sunlight transformed into usable energy? In exploring these and other questions, Dr. Asimov clearly explains the vital process of photosynthesis and traces the efforts of scientists to understand its role in the fundamental chemistry of life."
