WGU D311 – Microbiology| Complete questions and answers, 100% verified| Latest Bacterial Structures: Nucleoid Irregular shaped region within the cell of a prokaryote that contains all or most of the genetic material Bacterial Structures: Plasmids Small, circular, double-stranded DNA molecules found in prokaryotic cells along side the main chromosomes; often carry genes, including antibiotic resistance to aid in organism survival Bacterial Structures: RibosomesResponsible for protein synthesis: Prokaryotes - have 70S in cytoplasm Eukaryotes - have multiple located throughout the cytoplasm and by ER Bacterial Structures: Inclusions Some prokaryotic cells store excess nutrients in these structures, aiding adaption to unstable environments by reducing osmotic pressure Bacterial Structures: Endospores Are specialized structures formed by certain bacteria to protect their genetic material in a dormant state during unfavorable conditions; Ex: archaea Bacterial Structures: Plasma MembranePresent in all cells, encloses the cytoplasm, internal structures, and regulates molecule passage; consists of lipids and proteins that move fluidly: Prokaryotes: Nuclear Envelope Bacterial Structures: Cell Wall Protects the cells from harsh environmental conditions; Bacteria: primarily comprised by peptidoglycan, while archaea have pseudopeptidoglycan or other structures; Gram-positive: have thick peptidoglycan layers containing teichoic acids Gram-negative: have thinner peptidoglycan layers with an outer membrane containing lipoplycaccharides Bacterial Structures: Flagella
