  2. Five Kingdoms of organisms • Kingdom Prokaryota • Kingdom Protoctista • Kingdom Fungi • Kingdom Plantae • Kingdom Animalia

  3. Kingdom Prokaryota • Unicellular and colonial • including true bacteria

  4. Kingdom Prokaryota • Shape: spherical/rod-shaped /helical • Example: Rod-shaped

  5. Kingdom Protoctista • Unicellular protozoans and unicellular & multicellular algae • Mostly aquatic and live in seawater, freshwater ponds, lakes and streams.

  6. Kingdom Protoctista • Example: Coralline Alga (Calliarthron tuberculosum)

  7. Kingdom Fungi • Have no true roots, stems and leaves and vascular bundles • Hyphae for anchorage and absorption • Lack chlorophyll->saprophytic

  8. Kingdom Fungi • Example:

  9. Kingdom Plantae • Eukaryotic, photosynthetic organisms (contains chlorophyll) • Mosses • Ferns • Gymnosperms • Angiosperms

  10. Mosses • Primitive land plants • Possess tiny rhizoids • Upright, stem-like structure • Do not have vascular tissue

  11. Mosses • Example: mosses in gorge

  12. Ferns • A group of terrestrial plants • Grow in shady and humid places • Posses stems, leaves and vascular tissue

  13. Ferns • Example:

  14. Gymnosperms • Naked seeds • No fruit because no ovary • Usually cones on which sporangia and spores develop • No vessels in xylem, only tracheids, no companion cells in phloem

  15. Gymnosperms • Example:

  16. Angiosperms • Seeds enclosed in ovary • Produce flowers in which sporangia and spores develop • After fertilization, ovary develops into a fruit • Xylem contains vessels; phloem contains companion cells

  17. Angiosperms • Example: angiospermmonocot angiosperms

  18. Kingdom Animalia • Multicellular animals, without cell walls and without photosynthetic pigments, forming diploid blastula

  19. Kingdom Animalia • Chordates-posses notochord • a single, dorsal and hollow nerve cord • paired gill slits developed on the sides of the embryonic pharynx. • Fishes • Amphibians • Reptiles • Birds • Mammals

  20. Kingdom Animalia • Chnidarians • Annelids • Molluscs • Arthropods • Echinoderms

  21. Fishes • Aquatic • Stream-lined body, propulsive tail • Paired pectoral and pelvic fins • Unpaired median fins to maintain stability • Gills as respiratory organs • Single circulation • Prominent lateral line system • Exoskeleton of scales

  22. Fishes • Example:

  23. Amphibians • Smooth most skin without scales (act as respiratory surface) • No external ear • Semi-terrestrial; dependent on fresh water for development • External fertilization • Urea and ammonia excreted • Teeth uniform, only one type of tooth in dentition

  24. Amphibians • Example:

  25. Reptiles • Dry hard scales • Lungs as respiratory organs • No pinna to ear • Uric acid excreted • Internal fertilization • Completely adapted to life on dry, both in adults and during development

  26. Reptiles • Example:

  27. Birds • Body covered by feathers • Endothermic • Bones are light and strong • Lungs as the respiratory organs • Fore Pectoral limbs modified to wings • No teeth • No pinna • Bipedal method of walking • Internal fertilization • Uric acid excreted • Acute sense of light, colour vision, extensive visual field

  28. Birds • Example:

  29. Mammals • Endothermic • Skin covered by hair • Lungs as respiratory organs, diaphragm present to increase efficiency of the respiratory system • Pinna present • Internal fertilizaion

  30. Mammals • Example:

  31. Chnidarians • Diploblastic metazoa: ectoderm and endoderm separated by mesogloea • Tissue level of organization achieved • The body wall encloses a central digestive cavity called enteron • No respiratory, circulatory or excretory system • body is radial symmetrical • presence of nematoblast

  32. Chnidarians • Example:

  33. Annelids • Matamerically segmented • Triploblastic coelomate • Body covered with thin cuticle • Chaetae typically present • Closed circulatory system

  34. Annelids • Example:

  35. Molluscs • triploblastic coelomate • soft body divided into head, foot and visceral mass • shell may be one spiral piece or with 2 valves joined by ligaments, or may be enclosed inside the mantle • blood contains respiratory pigment, circulated through an open circulatory system

  36. Molluscs • Example:

  37. Arthropods • bilaterally symmetric • metamerically segmented • coelomate ,but body cavity consists of a haemocel, and the coelom is much reduced to cavities of the gonads and the excretory organs • chitinous jointed exoskeleton • open blood system

  38. Arthropods • Example:

  39. Echinoderms • penta-radial symmetrical • star-shaped • with calcerous spines on upper surface • possession of a water vascular system, a complex tubes surrounding the mouth and passing into the arms and tube feet • anus in the centre of aboral surface • mouth in the middle of oral surface

  40. Echinoderms • Example:
