1. Diversity of Life

2. The 5 Kingdom System
Kingdom
Phylum
Class
Order
Family
Genus
Species

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

4. Five Kingdom System
Monera
Protista
Fungi
Animalia
Plantae

5. Monera (Bacteria) Unicellular No nucleus Autotrophic or Heterotrophic
Prokaryotic
Autotrophic or Heterotrophic
Saprophytic: feed on dead substances
Parasitic: obtain nutrients from living organisms

6. Protists Unicellular Nucleus present Autotrophic or Heterotrophic
Eukaryotic
Autotrophic or Heterotrophic
Algae

7. Fungi Eukaryotic, mostly multicellular (yeast is unicellular)
No roots, stems or leaves
No chlorophyll, are heterotrophic
Saprophytic or parasitic
Reproduce by forming spores

8. Animals Eukaryotic, Multicellular, Heterotrophic
Divided into two groups according to the presence or absence of backbone:
Invertebrates : without backbone
Vertebrates (Chordates) : with backbone

9. Invertebrates

10. Invertebrates continued

11. Invertebrates continued

12. Vertebrates (Chordates)
Divided into 5 groups:
Fish
Amphibians
Reptiles
Birds
Mammals

13. Fish Aquatic Cold-blooded Body covered with wet and slimy scales
Streamline body for easy movement through water
Fins for balance and to control movement
Gills for breathing
External fertilization

14. Amphibians Cold-blooded Moist, scaleless skin Limbs present
tetrapods
Larvae (tadpoles) use gills for breathing; adults use lungs
External fertilization

15. Reptiles Cold-blooded Body covered with dry, hard scales Live on land
Breathe with lungs
Internal fertilization; lay shelled eggs

16. Birds Warm-blooded With feathers With wings Beak for feeding
Lungs for breathing
Internal fertilization; lay shelled eggs

17. Mammals Warm-blooded Hairs on skin
Females have mammary glands for producing milk
Lungs for breathing
Diaphragm present
Internal fertilization; embryos develop inside mothers’ bodies

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

19. Non-flowering plants
include:
Mosses
Ferns
Gymnosperms

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

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

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

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