Transcript

  • 1. BIOLOGY as the study of LIFE
  • 2. <ul><li> WHAT IS BIOLOGY? </li></ul>
  • 3. What are the CHARACTERISTICS OF LIFE <ul><li>Cell </li></ul><ul><li>Genetic material </li></ul><ul><li>Energy use </li></ul><ul><li>Homeostasis </li></ul><ul><li>Growth and development </li></ul><ul><li>Reproduction </li></ul><ul><li>Response to environment </li></ul><ul><li>Evolution </li></ul>
  • 4.  
  • 5. CELLS <ul><li>All living things are composed of one or more cells </li></ul><ul><ul><li>Except the virus, why? </li></ul></ul>
  • 6. ENERGY USE <ul><li>All organisms use energy </li></ul><ul><li>The creation and use of energy is called metabolism </li></ul><ul><ul><li>Anabolism, </li></ul></ul><ul><ul><li>catabolism </li></ul></ul>
  • 7.  
  • 8. HOMEOSTASIS <ul><li>Ability to maintain a stable internal environment to remain alive </li></ul><ul><ul><li>Give examples that should be maintained to be alive. </li></ul></ul>
  • 9. GROWTH <ul><li>Growth and change is present in organisms and these lead to their development </li></ul>
  • 10.  
  • 11. REPRODUCTION <ul><li>The mechanism of organisms to maintain the proliferation of their species </li></ul><ul><ul><li>Asexual </li></ul></ul><ul><ul><li>sexual </li></ul></ul>
  • 12.  
  • 13. Genetic Material <ul><li>All living things are made up of a kind of genetic material </li></ul>
  • 14. Response to stimuli <ul><li>Living organisms tend to react to certain factors that originate from their environment </li></ul><ul><ul><li>Tropism- movement towards/away w/o complete motility </li></ul></ul><ul><ul><li>Taxis- movement towards/away with complete motility </li></ul></ul><ul><ul><li>Kinesis- non-directional response to stimuli </li></ul></ul>
  • 15.  
  • 16. Evolution <ul><li>The driver of speciation </li></ul><ul><li>Is an emergent property of population </li></ul>
  • 17. THEMES OF BIOLOGY <ul><li>Emergent properties </li></ul><ul><li>The cell </li></ul><ul><li>Heritable information </li></ul><ul><li>Structure to function relationship </li></ul><ul><li>Interaction with the Environment </li></ul><ul><li>Regulation (homeostasis) </li></ul><ul><li>Unity and diversity </li></ul><ul><li>Scientific inquiry </li></ul><ul><li>Science, Technology and Society </li></ul>
  • 18. Emergent Property <ul><li>Recall: HBO </li></ul>
  • 19.  
  • 20. Structure to function relationship <ul><li>The role of a particular part or structure is determined through its form </li></ul><ul><ul><li>Structure fits the function </li></ul></ul><ul><ul><li>Plays a role in determining the role of an organism in the environment </li></ul></ul>
  • 21.  
  • 22.  
  • 23.  
  • 24. Unity and diversity <ul><li>Diversity is the sum of all the variety of all organisms in the biosphere </li></ul><ul><li>The varied organisms play a role (niche) in the stabilization of the whole system </li></ul>
  • 25. Scientific Inquiry and Sci, Tech and Society <ul><li>The scientific method is a tool in creating answers to the problems inquired by man in their environment </li></ul>
