Chapter 7 – Membrane Structure and Function - 2013 1. The first cells to live on earth were prokaryotic and were not internally compartmentalized. The fact that compartmentalized eukaryotic cell based life has largely replaced prokaryotic forms of life is a testament to the superior nature of this form of cell structure.
