  1. Communities

  2. What is living?

  3. Microscope

  4. Cells All living things are made up of cells and cells are only produced form other cells.

  5. Animal vs Plant Cell basic

  6. Classification The 5 Kingdoms

  7. Monera (bacteria) vs Protista • Monera= Prokaryotic, therefore have no nucleus. • Protista = Eukaryotic, therefore have a true nucleus.

  8. Bacteria reproduction • http://www.youtube.com/watch?v=gEwzDydciWc

  9. Bad bacteria?

  10. Good Bacteria

  11. Protists

  12. What makes Fungi different from plants? They are not classified as plants since they cannot photosynthesis and be an Autotroph. Also their cell walls different from plants and are made with chiten.

  13. Honey Fungus

  14. Plants! • What is special about plants? • How can they reproduce? • How do they make their own food? • How do they get water? • How do they get gases?

  15. Carnivores Plants

  16. Animals

  17. Animals • What makes an animals unique? • How do they reproduce? • What is the advantage of having variation amongst Animals, even within the same species?

  18. Animal Variation… Selective breeding

  19. Plant Classification • Liverworts and Mosses • Ferns • Gymnosperms (conifers) • Angiosperms (flowering plants) • Monocotyledons • Dicotyledons

  20. 1. Liverworts & Mosses • No true roots/stems/leaves • No special transport system • Reproduce with spores • Needs to live in moist area

  21. 2. Ferns • Have roots & stem • Leaves are called fronds • Reproduce by spores • Needs to live in Moist area

  22. 3. Gymnosperms (Conifers) • Cone-bearing (cone contains seeds) • Have roots, stems & leaves. • Leaves are needle like or flattened and thicker. • Can live in dryer areas

  23. 4. Angiosperms (flowering plants) Have roots, stems and leaves Reproduction occurs in flowers and produces seeds. Can live in a wide range of habitats • Monocotyledons – usually wind pollinated • Dicotyledons – usually insect pollinated

  24. Monocotyledons • Mono = one Hence there is only one Cotyledon in the seed. Usually wind pollinated Leaves parallel veins.

  25. Dicotyledons • Di = two Hence there is two cotyledons in the seed. Usually insect pollinated Leaves have a network of veins

  26. Animal Classification • Vertebrates – have a backbone. • Invertebrates - No back bone.

  27. Molluscs - Inverterbrate

  28. Insects - Inverterbrate • A small arthropod animal that has six legs and generally one or two pairs of wings. • Any small invertebrate animal, esp. one with several pairs of legs

  29. Arthropods? What is similar about all these? • Invertebrate • Exoskeleton • Segmented Body • Jointed legs

  30. Vertebrates - Mammals • Suckle their young (feed them milk) • Warm blooded • Most have fur or hair • Most give birth to live young • Breathe using lungs

  31. Vertebrates - Birds • Have feathers, beaks and scales on their legs • Lay hard shelled eggs • Are warm blooded • Breathe using lungs

  32. Vertebrates - Fish • Cold blooded • Live in water • Have fins and scales • Breathe using gills • Lay many eggs which do not have shells

  33. Vertebrates - Reptiles • Cold blooded • Mostly land animals • Scaly, dry skin • Breath using lungs • Most lay round, leathery eggs

  34. Vertebrates - Amphibians • Cold blooded • Have thin, moist skin • Young live in water, adults live on land and in water • Breath using gills or lungs • Lay many eggs which do not have shells

  35. Keys • An easy way to classify an organism. • There can be many different ways of styling a key. ie.

  36. What do the arrow show? Is Energy conserved? No. Energy is lost as heat at every step in the food chain.

  37. Why the pyramid shape? Can any other shape work for the Tropic levels? • The pyramid shape is important as it shows the produces as having the largest energy (or largest mass). • This is essential as all the higher tropic levels rely on getting their energy from the one below so the producer must supply all of this and more. • The producer will need to have excessive energy (and mass) over the higher levels so it can account for energy lost as heat, and energy for growth and reproduction.
