Question
Chapter 26.1, Problem 1R
Summary Introduction
To review:
The reason behind the fact that the development of a flexible cell surface was considered as a key event in the evolution of the eukaryotic cell.
Introduction:
The journey from prokaryotes to eukaryotes was a result of a change in the structure and functions over extended periods of time. It is presumed that the eukaryotic cells evolved from a prokaryotic cell with a firm cell wall. The prokaryotic Archean lost the firm cell wall over time and became a eukaryote.
