Pasteur proved that life must be present in order for new life to be generated. Most of the chemical reactions of life occur in aqueous solution within cells. Complete sets of genetic information are replicated and passed on during cell division. Viruses lack cellular structure but remain dependent on cellular organisms. Living organisms regulate their internal environment: cells are bathed in extracellular fluids, from which they receive nutrients and into which they excrete waste products, atom molecule cell tissue organ system organism po pulation community ecosystem biosphere.
