  1. Living Things Mr. Skirbst Life Science Topic 03

  2. Living Things * All living things (on Earth) share similar characteristics

  3. 6 Characteristics of Living Things 1. Made of cells

  4. 6 Characteristics of Living Things • Made of cells • Ability to move

  5. 6 Characteristics of Living Things • Made of cells • Ability to move • Perform complex chemical activities (ingestion, digestion, respiration, excretion)

  6. 6 Characteristics of Living Things • Made of cells • Ability to move • Complex chemical activities • Grow and develop

  7. 6 Characteristics of Living Things • Made of cells • Ability to move • Complex chemical activities • Grow and develop • Respond to stimulus

  8. 6 Characteristics of Living Things • Made of cells • Ability to move • Complex chemical activities • Grow and develop • Respond to stimulus • Reproduce

  9. Origins of Life Spontaneous Generation Theory - stated that living things came from non-living matter, all by itself

  10. Origins of Life Francesco Redi (Italy, 1668)

  11. Origins of Life Francesco Redi (Italy, 1668) - disproved theory with his famous experiment (meat & flies)

  12. Origins of Life Francesco Redi • He showed that “living things do NOT come from non-living matter.”

  13. Origins of Life Francesco Redi • He showed that “living things do NOT come from non-living matter.” • “Living things come from living things.”

  14. 6 Basic Needs of Living Things • Energy primary source is the sun

  15. 6 Basic Needs of Living Things • Energy • Food (provides chemical nutrients)

  16. 6 Basic Needs of Living Things • Energy • Food • Water (allows chemical activities to occur)

  17. 6 Basic Needs of Living Things • Energy • Food • Water • Oxygen (from air or water)

  18. 6 Basic Needs of Living Things • Energy • Food • Water • Oxygen • Living Space (competition for resources)

  19. 6 Basic Needs of Living Things • Energy • Food • Water • Oxygen • Living Space • Temperature

  20. Testing for Life Can soil from another planet be tested for life?
