by Franklin M. Harold
Addressing the perennial question, What is life? Harold focuses on microorganisms in order to explore how chemistry and biology interact to maintain life. In particular, the author uses the bacterium Escherichia coli to illustrate a cell's ability to take in energy from the environment, maintain order, and adapt to change. After establishing these criteria for living, Harold delves into cellular structures and the evolution of cells and their parts. These provocative questions round out the text: What makes life exist in the first place? What is the origin of life?
