Prokaryotic Cell Structure Outside the cell wall Glycocalyx Negative staining technique Capsule Slime layer Flagella Gives motility towards food (chemotrophic), light (phototropyic) Monotrichous Lophotrichous Amphitrichous Peritrichous Fimbrae provide attachment, G- bacteria – Pili used to share DNA segments, a form of sexual – reproduction Cell wall responsible for cell shape, controls osmotic – movement. Made up of several materials, depending on species. Peptidoglycan typical component Some bacteria have lipid in their cell wall, special cell wall staining techniques Gram staining procedure Adhere to clean, dry slide.
