  1. Characteristics of Living Things Cambridge IGCSE Biology ClickBiology

  2. There are 7 characteristics of living organisms: • Movement • Respiration • Sensitivity • Growth • Reproduction • Excretion • Nutrition MRS GREN

  3. Movement • Achange of position or place.

  4. Respiration • A chemical process in which oxygen is used to release energy from sugar molecules. Sugar (C6H12O6) reacts with oxygen (O2) to form Carbon dioxide (CO2), water (H2O) and ENERGY

  5. Sensitivity • The ability to detect or sense changes in the environment (stimuli) and to make responses.

  6. Growth • A permanent increase in size by increasing cell number or cell size or both.

  7. Reproduction • The process that makes more of the same kind of organism

  8. Excretion • The removal of toxic materials, waste products and excess substances from an organism

  9. Nutrition The process in which nutrients are taken into the body and converted into simpler substances used for energy, growth and tissue repair.

  10. Summary • Movement • Respiration • Sensitivity • Growth • Reproduction • Excretion • Nutrition

  16. Question 5: Sensitivity and Movement Which two characteristics are shown by this animation:

  17. Question 6: Sensitivity and Nutrition Other than movement, which characteristics are shown by this animation:

  18. Question 7: Growth and Respiration So far you should have named a total of five different characteristics. However there are 7 characteristics in total. Name the two remaining characteristics.
