1.1 Understand that living organisms share the following characteristics:


  • they require nutrition
  • they respire
  • they excrete their waste
  • they respond to their surroundings
  • they move
  • they control their internal conditions
  • they reproduce
  • they grow and develop.


What you need to know is that to be a living organism you must do all of the above.

A good way to remember this is a pneumonic: Mrs C. Gren is one example, trying to think of the colour sea green may help.

Movement
Respiration
Sensitivity
Control
Grow
Reproduce
Excrete
Nutrition

Here, C can be replaced by H to represent homoeostasis (control of internal conditions).
