1.1 Understand that living organisms share the following characteristics...

Note that I cut out a bit because I'm basically just going to list the things that the spec. point listed anyway...

Living organisms:

Move, respire, require nutrition, excrete waste, respond to surroundings, control their internal conditions, reproduce and grow/develop. A way to remember this is Mrs Grenc:

Move

Respire

Sense (respond to surroundings)

Control of internal conditions

Reproduce

Excrete

Nutrition (require nutrition)

Grow

(Note that for IGCSE purposes, you have to make it Mrs Grenc with a "c" at the end.)
