, Describe the differences in cell biology between
bacteria, fungi, virus and prion
• Bacteria • Fungi
– Prokaryotes – Eukaryotes
– Simple, no defined – Larger, more complex
nucleus or organelles, – Nuclear membrane,
small organelles
– Reproduce by binary – Moulds, yeasts
fission (rapid)
– Free-living
– Absorb nutrients from
environment
, Describe the differences in cell biology between
bacteria, fungi, virus and prion
• Virus • Prion
– Very small – Infectious particle
– No cell wall or cellular consisting of misfolded
activity proteins
– Can’t reproduce by – Causes
binary fission neurodegenerative
– Only have < 3 diseases
components • Viroid
– Not living? – Short pieces of RNA
– Plant pathogens
