Their Structure and Representation. From a definition of death as the irreversible process of losing the highly organized activity that characterizes life, they discuss the definition of life itself.

We also found in the analyzed textbooks an informational view of life. Autopoietic systems, replicators, and the search for a meaningful biologic definition of life.

Emmeche observes that definitions of life are seldom discussed in depth or even mentioned in biology textbooks and dictionaries.

This argument is not sufficient, however, for avoiding a violation of the Cell Theory by viruses, as this theory states that the cell is the basic structural unit of all living beings, and this does not hold in the case of viruses, no modeerna whether they are strictly dependent on cells or not.

What is the paradigm in which the textbook includes, implicitly or explicitly, the life definition if there is any?
