Form and function in cytology are simply different perspectives, as the two are inexorably intertwined. In this, the precepts of physics and chemistry provide the foundation for life. That withstanding, living is a matter of intelligently applying energy.
There is a constant flurry of communication and coordination in every cell. Chemical messages flit back and forth.
Cells maintain their integrity and reproduce via genetic material. Operationally, a cell’s genome is a massive instruction manual for producing proteins and other bioproducts. This manual expresses the language of life via coordinated conferencing.
Though the functions of prokaryotes and eukaryotes are comparable, the elaborate structure of even a single eukaryotic cell means that its communication needs are inherently more complex than those of a prokaryote.
