Definition of Life
Scientists have come up with over a hundred different definitions of the term "life". Many definitions are similar. They usually belong to one of five categories.

Definitions
Life is a system that has a metabolism, can grow, multiply and move as well as change through mutation. Definitions should help to avoid misunderstandings when working together. Scientists have therefore developed quality criteria for definitions.
 * Enumeration of properties

With enumerations, a problem arises with classification if not all criteria are met. Enumerated definitions are of low quality.

Life is diverse. Each of these definitions illuminates different aspects of life.
