Chapter Learning Objectives Chapter 27: Prokaryotes Concept 27.1: Structural and functional adaptations contribute to prokaryotic success Describe the structure and function of each of the following prokaryotic features: o Capsule o Fimbria o Sex pilus o Nucleoid o Plasmid o Flagellum Describe the structure, composition, and functions of prokaryotic cell walls. Distinguish the structure and staining properties of gram-positive bacteria from those of  gram-negative bacteria. Explain how the organization of prokaryotic genomes differs from that of eukaryotic  genomes. Concept 27.2: Rapid reproduction, mutation, and genetic recombination promote genetic  diversity in prokaryotes List three factors that give rise to high levels of genetic diversity in prokaryotes. Describe three processes that produce recombinant DNA in prokaryotes. Concept 27.3: Diverse nutritional and metabolic adaptations have evolved in prokaryotes
