Bacteria are a category of prokaryotes with cell walls made of correct answers peptidoglycan Appendages for Motility correct answers flagella and axial filaments Appendages for attachment sites or channels correct answers pili and fimbriae Structure of flagellum (3 parts) correct answers filament, sheath and basal body Flagellar Response correct answers They're sensory (chemotaxis) run and tumble locomotion & steering spirochetes, corkscrew shaped bacteria correct answers serpentine locomotion by 2 or more coiled threads (periplasmic flagella or axial filaments) Non Flagellar appendages correct answers Fimbria (smaller & common, like a bristle) and Pili (specialized functions) Bacterial Conjugation is correct answers the direct transfer of genetic material (DNA) via Pili from one bacterial cell to another Glycocalyx correct answers Slime layer for protection and adherence Capsules correct answers composed of mucoid (sticky) polysaccharides Gram Positive correct answers thick cell wall of peptidoglycan and the cell membrane (traps the crystal violet) Gram Negative correct answers thin layer of peptidoglycan, allowing easy removal of crystal violet (the alcohol actually removes the outer membrane) Peptidoglycan (PG) correct answers long chain macromolecules that form the component of bacterial cell walls Periplasmic space correct answers The space between the inner and outer cell membranes in Gram-negative bacteria.
