Edexcel IGCSE Biology 复习笔记 1.1.1 The Unifying Characteristics of Living Organisms

• In order for something to be considered 'living', it must fulfil specific criteria that are true of all living organisms
• These criteria can be remembered using the acronym MRS C GREN
  • Movement
  • Respiration
  • Sensitivity
  • Control
  • Growth
  • Reproduction
  • Excretion
  • Nutrition

   

• If something does not carry out all of these life processes, it is either dead or non-living
• Viruses are a good example of non-living particles/agents
