Characteristics of life2012

  1. 1. Characteristics of Living Things (pg 8)
  2. 2. All living things:
  3. 3. 1. Share a universal genetic code • All organisms use DNA to store the information they need to live, grow, and reproduce
  4. 4. 2. Grow and Develop • Growth can involve adding more cells, or cells getting larger • Development = changes during a lifetime
  5. 5. 3. Respond to their environment • Detect a condition in the environment (a stimulus) and respond
  6. 6. 4. Reproduce • Production of offspring (Sexual or Asexual)
  7. 7. 5. Maintain a stable internal environment • Keeping a constant internal environment, even when external conditions change dramatically, is called homeostasis
  8. 8. 6. Obtain and use material and energy • Chemical reactions that break down materials and then reassemble them to build the organism are called metabolism
  9. 9. 7. Groups of organisms evolve over time • All living things share a common origin more than 3.5 billion years ago and have evolved over time into the species present today
  10. 10. 8. Made of cells • All living things are composed of one or more cells
  11. 11. Output (pg 9) • Foldable
