bakteeria
Bakteeria are a diverse group of unicellular microorganisms forming a major domain of life. They are prokaryotes, lacking a membrane-bound nucleus and other organelles. Most bakteeria have cell walls made of peptidoglycan and display shapes such as cocci (spheres), bacilli (rods), and spirilla. They inhabit nearly every environment, from soil and water to living bodies, and can endure extreme conditions.
Reproduction is usually asexual, primarily by binary fission, yielding two daughter cells. Genetic diversity arises through
Diversity and classification: Bakteeria are organized into numerous phyla within the domain Bacteria. They are commonly
Ecology and roles: They drive nutrient cycles, decompose organic matter, and some photosynthetic groups contribute to
Human relevance: Bakteeria underpin microbiology, medicine, and biotechnology. They are studied via culture, genomics, and imaging
