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

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)
