  1. 1. UNIT 3: A PLANET FULL OF LIFE
  2. 2. <ul><li>A living thing is an organism that is able to perform three vital functions: nutrition, interaction and reproduction. </li></ul><ul><li>All living things are made of cells. </li></ul><ul><li>Nutrition: </li></ul><ul><ul><li>Autotrophs: They produce their own food. </li></ul></ul><ul><ul><li>Heterotrophs: They eat another organisms. </li></ul></ul><ul><li>Reproduction: </li></ul><ul><ul><li>Asexual: Produces identical copies of itself </li></ul></ul><ul><ul><li>Sexual: Two living things join and provide gametes. </li></ul></ul>
  3. 3. TYPES OF CELLS <ul><li>Prokaryotic cells: They don’t have a nucleus. </li></ul><ul><li>Eukaryotic cells </li></ul><ul><ul><li>Animal cell </li></ul></ul><ul><ul><li>Plant Cell </li></ul></ul>
  4. 5. THE FIVE KINGDOMS <ul><li>Monera kingdom: Ex: Bacterias </li></ul><ul><li>Protoctist kingdom: Protozoa and Algae. </li></ul><ul><li>Fungi kingdom: Ex: Mould and Mushrooms. </li></ul><ul><li>Plant kingdom: Ex: Oak tree </li></ul><ul><li>Animal kingdom : Ex: Dog </li></ul>
