  1. Name the seven characteristics of a living organism:
    • Movement
    • Respiration
    • Sensitivity
    • Growth
    • Reproduction
    • Excretion
    • Nutrition
  2. What is Movement?
    This is the Change in position of a whole organism or part of and organism. (e.g. Monkey)
  3. Movement: Give an example of an animal that can move its whole body from place to place.
    A dog
  4. Movement:Give an example of an animal that can only move parts of its body.
    Coral moves just their tentacles.
  5. Movement:What part of a plant moves and where does that part move to?
    Plants move their roots towards water
  6. Respiration:Define Respiration
    Respiration is the process by which energy is released from food.
  7. Define Aerobic respiration
    This is when energy is released from food using oxygen and takes place in most cells.
  8. What is the formula for Aerobic Respiration
    • C6H12O4+6O2⇒6CO2+6H2O+ENERGY
    • glucose+oxygen⇒carbon dioxide +water+energy
  9. Define Anaerobic respiration
    Anaerobic respiration is when energy is released from food and doesn't involve oxygen. It takes place in some cells such as some bacteria and yeast.
  10. What is Sensitivity?
    Sensitivity is the ability of organisms to detect and respond to changes in the environment or within themselves
  11. Sensitivity - What causes these changes in Sensitivity?
    These changes are caused by stimuli and are detected by receptors (sense organs) e.g. light is a stimulus detected by the eyes which are our receptors. Plants detect sunlight and grow towards it.
  12. Define Growth
    Growth is the permanent increase in size and  complexity of an organism. Growth occurs by an increase in the number of cells and/or size of cells in an organism.
  13. What is Reproduction?
    Reproduction is the process in which living organisms make new organisms with similar characteristics of their parents. Replication of the parents coded information needs to take place in order for the organisms to look and behave like their parents.
  14. Reproduction - How many types of reproduction are there?
    • There are two types of reproduction - a. Asexual reproduction - requires only one organism e.g. Bacteria, (binary fission), starfish, worms, sugar cane.
    • b. Sexual reproduction - requires 2 organisms.
  15. What is Excretion?
    Excretion is the process by which waste and harmful substances are removed from the body. This waste and harmful substances are produced by the body's metabolism.
  16. Excretion. What is metabolism?
    Metabolism is all of the chemical reactions taken place in the body. E.G. Ammonia is formed when the body breaks down protein. It is removed from the body as urea when we urinate. Ammonia is toxic.
  17. What is Nutrition (feeding)?
    • Nutrition is the process by which living organisms...food. Organisms that take in ready-made food and are called...
    • Organisms that make their own food and are called....

Description:
Biology is the study of living organisms. All living organisms from the simplest unicellular organism to the most complex multicellular organism carry out all 7 of these characteristics.
