Introduction: The Ubiquity and Importance of Prokaryotes Prokaryotes—encompassing Bacteria and Archaea—dominate Earth’s biosphere in both numbers and diversity. Despite their microscopic size, they are foundational to all ecosystems, influencing nutrient cycles, environmental adaptation, and human health. Cell Structure and Genetic Diversity Cell Structure: Prokaryotes lack a nucleus and membrane-bound organelles. Their cell walls differ, c...
