  1. 1. Whats the odd one out and why?
  2. 2. B1. Characteristics of living organismsLesson Objective:1. List and describe the characteristics of livingorganisms.
  3. 3. Characteristics of living organisms- Respire- Irritability (Sensitivity)- Nourish- Grow and develop- Excrete- Reproduce RINGER
  4. 4. Respiration- Organisms use oxygen and nutrients to release energy- Oxygen is generally gained from the environment and taken in by gaseous exchange systems
  5. 5. Irritability• Organisms can detect changes to their environment• If conditions are extreme organisms will have to move (or die)
  6. 6. Nutrition• Organisms must take in food providing energy or materials for growth• Plants use photosynthesis to make their own food
  7. 7. Growth• Growth is a permanent increase in size and dry mass• Organisms generally grow as time goes on
  8. 8. Excretion• Removal of toxic waste from organisms
  9. 9. Reproduction• Sexual – fertilization to produce a new organism• Asexual – organism splits in two and produces two identical organisms
  10. 10. Questions1. When did the first living organism appear on earth?2. RINGER stands for what?3. Give two reasons why reproduction is so important for living organisms.
