Processes Of Life

  1. 1. Life Processes The Activities ALL living things need to perform to stay alive… from elephants to bacteria!
  2. 2. <ul><li>Write what is in black </li></ul><ul><li>What is in blue is optional </li></ul>
  3. 3. Organism <ul><li>Any living thing </li></ul><ul><li>6 Kingdoms </li></ul><ul><ul><li>Plant - Protists </li></ul></ul><ul><ul><li>Animal - Bacteria </li></ul></ul><ul><ul><li>Fungi - Archaebacteria </li></ul></ul>
  4. 4. Cell Theory <ul><li>All living things are made of cells </li></ul><ul><li>All life functions are performed by individual cells or groups of cells. </li></ul><ul><li>All cells come from preexisting cells. </li></ul>
  5. 5. Metabolism <ul><li>Life Functions = All the chemical reactions that occur in an organism </li></ul><ul><li>We are bundles of chemicals! </li></ul>
  6. 6. What are the Processes? <ul><li>STRANGER C </li></ul><ul><li>(Mnemonic) </li></ul>
  7. 7. Processes <ul><li>S ynthesis </li></ul><ul><li>T ransport </li></ul><ul><li>R espiration </li></ul><ul><li>A daptation/ Regulation </li></ul><ul><li>N utrition </li></ul><ul><li>G rowth/ G enetics </li></ul><ul><li>E xcretion </li></ul><ul><li>R eproduction </li></ul><ul><li>C ells </li></ul>
  8. 8. Synthesis <ul><li>“To Make” </li></ul><ul><li>Ex Dehydration Synthesis makes a bond </li></ul>
  9. 9. Transport <ul><li>Moving materials around the organism </li></ul>
  10. 10. Respiration <ul><li>Creating/Using the Energy </li></ul><ul><li>Energy = ATP molecule </li></ul><ul><li>Aerobic – “With Oxygen” </li></ul><ul><li>Anaerobic – “Without oxygen” </li></ul>
  11. 11. Adaptation/ Regulation <ul><li>Organism changes to “fit” environment </li></ul><ul><li>Adaptation – Gradual change over time (aka Evolution) </li></ul><ul><li>Regulation – Maintaining a constant state inside the organism = homeostasis </li></ul><ul><ul><li>Stimulus outside  change inside </li></ul></ul><ul><ul><li>Low temperature  shiver </li></ul></ul>
  12. 12. Nutrition <ul><li>Getting the raw materials (molecules) necessary for synthesis </li></ul>
  13. 13. Growth/Genetics <ul><li>Growth – An increase in the size or number of cells </li></ul><ul><li>Genetics – code that is passed from one generation to the next </li></ul><ul><li>DNA </li></ul><ul><li>Blueprint for protein synthesis </li></ul>
  14. 14. Excretion <ul><li>Getting rid of metabolic wastes </li></ul><ul><li>#2 is NOT excretion, #1 is! </li></ul><ul><li>Exhaling IS excretion </li></ul>
  15. 15. Reproduction <ul><li>Not necessary for the individual organism…but necessary for survival of the species </li></ul><ul><li>Asexual – one parent, duplicate genetic code </li></ul><ul><li>Sexual – two parents, recombination of genes </li></ul>
  16. 16. Life Span <ul><li>All living things must eventually die </li></ul><ul><li>Average Life Span of Humans 87 years </li></ul><ul><li>Some cells live only 20 minutes </li></ul>
  17. 17. Cells <ul><li>All living things are made of cells ! </li></ul>
  18. 18. Levels of Organization Small/ Simple Big/ Complex Multicellular organisms Cells Cell Organelles Organic molecules
