Prokaryotes, viruses and microorganisms

By the end you’ll be able to

• Describe the structure of a typical bacterial cell, including cytoplasm, cell membrane, cell wall, circular chromosomal DNA, plasmids and, where specified, slime capsule and flagellum.
• Compare prokaryotic cells with eukaryotic cells in terms of size, internal organisation and the absence of a nucleus and other membrane-bound organelles in prokaryotes.
