14. 6 Kingdoms of Life The Six Kingdoms: How are organism placed into their kingdoms? Cell type: complex or simple Their ability to make food The number of cells in their body Presence of nucleus Type of genetic material 14

15. Kingdom Bacteria Evolved 3 to 4 billion years ago Single celled Prokaryotic Make or absorb food Cell wall – peptidoglycan

16. Kingdom Archaea Evolved 3 to 4 billion years ago Single celled Prokaryotic Make or absorb food DNA - Similar to Eukaryotic Cell wall – Pseudopeptidoglycan or protein only

17. Kingdom Protista Evolved 1.5 billion years ago Single celled Has a nucleus Eukaryotic Ingest or produce food

18. 18 Kingdom Fungi Evolved 1 billion years ago Multicellular Eukaryotic Cell wall – Chitin Absorb food

19. Kingdom Plantae Evolved 700 million years ago Multicellular Eukaryotic Cell wall – Cellulose Produces food – photosynthesis

20. Kingdom Animalia Evolved 500 million years ago Multicellular Eukaryotic No cell wall Ingests food Mobile
