Document Summary
Prokaryotic cell structure and function: shape and arrangement of cells, size of cells, prokaryotic cell organization. Eukaryotic cells are more complex, they contain numerous organelles: highly evolved. In eukaryotes the dna is contained in a nucleus. Procaryotic cells are surrounded by a cell wall of peptidoglycan. Helical or spiral cells: spirilla/ spirillum. S. aureus: chains pile in golden rod formation. Spiroplasma: is a genus of mollicutes, without cell walls. Hyphomicrobium: is a genus of gram-negative, non-spore-forming, rod-shaped bacteria, stick to surfaces with nutrients using hypha. G. furrginea: stick to surfaces and colonize, remove themselves from surfaces whne conditions get altered dangerously. Only surface/volume is bigger in bacteria than human cells: this allows them to grow much faster. Name means guest at a fishes banquet . Found in gut of brown surgeon fish. Volume 1000000 larger than e. coli: thiomargarita namibiensis (gram -) Size of a period at the end of a sentence: tiny eukaryote. In the size range of typical bacterial cell.
