Characteristics of living things

  1. 1. 6 Characteristics of All Living Things Got 4 or 5? It’s not alive!
  2. 2. Characteristics <ul><li>1. Cells – the basic unit of life; small and very complex </li></ul><ul><li>Unicellular –one cell </li></ul><ul><li>Multicellular – more than one cell </li></ul>
  3. 3. Characteristics <ul><li>2. Organization – occurs at the molecular and cellular level </li></ul><ul><li>Differentiation  different cells perform different functions for the organism. </li></ul>
  4. 5. Characteristics <ul><li>3. Energy Use – organisms require energy to survive, grow and reproduce. </li></ul><ul><li>Autotrophs  organisms that make their own food. Ex. Plants </li></ul><ul><li>Heterotrophs  organisms that must take in food for energy. Ex. Humans </li></ul>
  5. 7. Characteristics <ul><li>4. Homeostasis – a stable level of internal conditions. </li></ul><ul><li>Ex. Humans regulate internal body temperature. </li></ul>
  6. 9. Characteristics <ul><li>5. Growth – living things grow by cell division. </li></ul><ul><li>Ex. Humans made up of 50 trillion cells, which came from one cell (fertilized egg). </li></ul><ul><li>Nonliving things grow by accumulating more material. Ex. Icicles. </li></ul>
  7. 11. Characteristics <ul><li>6. Reproduction – organisms produce new organisms like themselves. </li></ul><ul><ul><li>It is essential for a species to survive </li></ul></ul><ul><li>Organisms transmit DNA (hereditary information) to their offspring. </li></ul>
  8. 13. Vocabulary Words <ul><li>1. Organism – a living thing. </li></ul><ul><li>2. Homeostasis – maintianing a stable level of internal conditions. </li></ul><ul><li>3. Autotroph – organisms that obtain their energy by making their own food (photosynthesis). </li></ul><ul><li>4. Heterotroph – organisms that obtain their energy by taking in food(eating). </li></ul><ul><li>5. Microscope – an instrument that produces an enlarged image of an object. </li></ul>
  9. 14. Voc. Words <ul><li>6. Ecology –study how organisms interact with each other and their environment. </li></ul><ul><li>7. Gene – a short segment of DNA that contains the instructions for the development of a single trait. </li></ul>
  10. 15. Voc Words <ul><li>8. Evolve – to change over time. </li></ul><ul><li>9. Natural Selection – a theory stating that organisms that have certain favorable traits are better able to successfully reproduce in nature. </li></ul><ul><li>10. Photosynthesis – a process by which some organisms capture energy from the sun (light energy) and convert it into a form of energy they can store (chemical energy). </li></ul>
