Chapter 5, Problem 2.3SC
Summary Introduction
To explain: The way in which the terms “cell wall, outer membrane, lipopolysaccharide, endotoxin, lipid A, and death of cells” are related to one another.
Introduction: Prokaryotes and eukaryotes are the basic cell types of all living cells. The prokaryotes are unicellular organisms that lack membrane-bounded nucleus and organelles. The eukaryotes possess a distinct nucleus that contains the genetic material of the cell.
