Chapter 4: Prokaryotic Cells and microorganisms
This chapter looks at the morphology, and pathogenic mechanisms of prokaryotic cells and microorganisms respectively. It discusses in detail the structural components, functions of the different organelles of prokaryotic cells as well as feeding and survival mechanisms of prokaryotic microorganisms.
Prokaryotic cells have a specialized cellular structure. Prokaryotes are unicellular and their cells have no cellular organelles, that is, a membrane does not surround their nucleus. These cells contain intricate phospholipids, sterols, and sphingolipids. They are typically 1-5µm in diameter .
Their outer surface is covered by glycocalyx, which is a gel like ...
