Bacteria Internal Structure

Not like other creature bacteria have very simple structure, because bacteria is a single cell. As single cell bacteria only content nucleoid, ribosomes, storage granules, and endospore.
  • Nucleouid: is like a DNA cell, confined to the central region, bounded by a membrane and visible to distinct.
  • Ribosomes: give the cytoplasm of bacteria a granular appearance in electron micrographs. Though smaller than the ribosomes in eukaryotic cells, these inclusions have a similar function in translating the genetic message in messenger RNA into the production of peptide sequences.
  • Storage Granules: Nutrient and reserves may be stored in the cytoplasm in the form of glycogen, lipids, polyphosphate, or in some cases, sulfur or nitrogen.
  • Endospore: Some bacteria like Clostridium botulinum, form spores that are highly resistant to drought, high temperature and other environmental hazards.
