  • Non-living, parasitic, cause disease, have protein coat and nucleic acid (RNA or DNA)
• Viruses structures have Spikes that can recognise cells to infect them

  , DNA OR RNA, protein coat
• Bacteria cells have cell membrane, peptidoglycan cell wall, plasmids, flagella, ribosomes, cytoplasm and some have slime capsules
• Fungal cells have cell membrane, cell wall, nucleus, mitochondria, and vacuole
