Chapter Learning Objectives Chapter 27: Prokaryotes Concept 27.1: Structural, functional, and genetic 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 List the three domains of life. 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: A great diversity of nutritional and metabolic adaptations have evolved in  prokaryotes Distinguish, with prokaryotic examples, among photoautotrophs, chemoautotrophs,
