1. Diversity of Organisms and Classification

2. Classification of Organisms
Kingdom
Phylum / Division
Class
Order
Family
Genus
Species

3. Species
The smallest group of organisms classified which can interbreed with each other to produce fertile offspring

4. Six Kingdom System Archaebacteria Eubacteria Protists Fungi Animals
Plants

5. Bacteria Kingdoms
Split into two kingdoms according to chemical make-up
Unicellular
No nucleus
Prokaryotic
Heterotrophic or Autotrophic

6. The Bacteria Kingdoms Archaebacteria
One of the oldest life forms on Earth
Live in extreme environments
Eubacteria
Very common bacteria
Found on almost every surface

7. Protist kingdom Unicellular or Multicellular Nucleus present
Eukaryotic
Autotrophic or heterotrophic

8. Fungus kingdom Eukaryotic No root, stem and leaf No chlorophyll
Heterotrophic
Reproduce by forming spores

9. Animal Kingdom Eukaryotic
Divided into two groups according to the presence or absence of backbone:
Invertebrates : without backbone
Vertebrates : with backbone

10. Invertebrate
Cnidarians
Echinoderms
Annelids
Arthropods
Mollusks

11. Cnidarians Stinging Animals with no backbone
Include the jellyfish, corals, sea anemones, and box jellyfish
Most are found in oceans

12. Annelids Include earthworms, leeches, and some Marine worms
All have segmented bodies and bristles

13. Mollusks
Soft and unsegmented body
Sometimes covered by a hard shell

14. Echinoderms Marine animals with 5-radial plan body
Have external spines
Such as starfish, sand dollar, and sea urchin

15. Arthropods Segmented body Have a hard exoskeleton and several pairs
of jointed legs
Divided into 4 classes
Crustaceans
Arachnids
Myriapods
Insects

16. Vertebrates Also called the Chordates Divided into 5 groups: Fish
Amphibians
Reptiles
Birds
Mammals

18. Plant Kingdom Eukaryotic
Most plants contains photosynthetic pigments (e.g. chlorophyll) for photosynthesis
Autotrophic
Can be divided into two groups:
Non-flowering plants
Flowering plants

19. Non-flowering plants
4 groups:
Algae
Mosses
Ferns
Gymnosperms

20. Mosses With simple leaves and stems
No root; with rhizoids for anchorage and absorption of water
Reproduce by spores
No vascular tissues
Found in damp area

21. Ferns With true roots, stems, leaves and vascular tissues
Reproduce by spores
Live in damp places

22. Conifers Reproduction by producing seeds
Seeds develop in cones, not enclosed by fruits
 naked seeds
Needle-shaped leaves to reduce water loss

23. Flowering plants With flowers for reproduction
Seeds are produced inside the fruit (matured ovary)
