- The vital functions of organisms take place within cells through biochemical processes, and are controlled by substances secreted by cells.
- Cells have diverse structures and delimited sectors that allow them to fulfill vital functions in the entire organism: birth, nutrition, metabolism, reproduction, growth, death.
