Bacteria
Q: What are bacteria?
Answer:
Bacteria are prokaryotic microorganisms lacking a true nucleus and membrane-bound organelles.
Q: Where can bacteria be found?
Answer:
Bacteria can be found in almost every environment on Earth, from soil and water bodies to extreme environments like hot springs, acid mine drainage, and frozen Arctic tundra.
Q: What is the structure of bacteria?
Answer:
Bacterial cells consist of a cell envelope, cell wall, plasma membrane, and appendages (pili, fimbriae, and flagella). They also contain internal structures like mesosomes, ribosomes, nucleoids, plasmids, and inclusion bodies.
Q: How do bacteria obtain nutrition?
Answer:
Bacteria exhibit diverse nutritional strategies. Autotrophic bacteria like chemoautotrophic, oxygenic photoautotrophic, and anoxygenic photoautotrophic bacteria, and Heterotrophic bacteria like saprophytic, parasitic, and symbiotic bacteria
Q: How do bacteria reproduce?
Answer:
Bacteria reproduce rapidly through asexual means like fission and spore formation. They also engage in sexual reproduction through transformation, transduction, and conjugation, allowing for genetic diversity.
