Transcript

  • 1. <ul><li>By: Josehpine M. Maningas </li></ul><ul><li>Biology Teacher </li></ul>
  • 2. Think of making a list of characteristics the “line” between life and nonlife there are certain accepted traits 1. Made of cells 2. Reproduce 3. Grow, develop 4. Obtain/use energy 5. Respond to the environment
  • 3. 1. Made up of CELLS • small, self-contained units • separated from it’s surroundings • can make an entire organism – called unicellular: • multicellular is made of many cells • Cells are never formed by non- living things
  • 4. 2. Living things REPRODUCE • This means they produce new organisms of the same type • individuals will die; thus they must reproduce if the group of similar organisms (species) will survive
  • 5. Two basic kinds of reproduction: 1. Sexual reproduction- requires 2 cells from different individuals unite 2. Asexual reproduction- a single organism can reproduce without the aid of another – some single-cell organisms will simply divide into two new cells
  • 6. 3. Grow and Develop • at some stage, living things are capable of growth: taking in materials from the surroundings and transforming it into living tissue – different from a snowball “growing” • development- a cycle of change
  • 7. • As development continues, a process called aging occurs – processes become less efficient – ability to reproduce ceases – death is the end result – life span: • Death is then also a process of change that separates living and nonliving
  • 8. 4. Obtain and Use Energy • energy comes from the surroundings, or environment • energy used to grow, develop, reproduce • Anabolism- process of putting together simpler materials into more complex materials (a building process)
  • 9. Plants- obtain energy from sunlight in a process called photosynthesis • photo- means light • synthesis- means put together • Animals cannot perform photosynthesis – they must take in energy in the form of food
  • 10. • Catabolism- breakdown of complex materials into simpler items • Living things have both anabolism and catabolism • Sum total of both is metabolism - the balance of all chemical reactions in the body3
  • 11. <ul><li>5. Respond to the environment </li></ul><ul><li>• some can be rapid, some are slow </li></ul><ul><li>• they react to a stimulus </li></ul><ul><li>– light, temperature, odor, sound, gravity, heat, water, pressure, etc. </li></ul><ul><li>• Irritability - ability to react to stimulus </li></ul><ul><li> • Homeostasis – a balance of conditions </li></ul>
  • 12. <ul><li>Thank you for listening!! </li></ul>
