GRIMNER
Growth
Reproduction

Nutrition
Excretion
Respiration
What is Nutrition?
Organism needs to obtain food for energy and to maintain life
What is Food?
Food can
Provide energy
Provide material for growth
Keep healthy
Do plants have nutrition?
Yes
Plants make their own food by photosynthesis
What is Respiration?
Break down food to get energy for body activities
What does Movement means?
Organism move freely
Can plants move?
Plants usually move by growing
What is Growth?
Organism increase in size and complexity permanently
What is Irritability?
Organism sense their internal and external environment and to respond it
What is Reproduction?
The process which Organism produce new individuals
What is Excretion?
Organism remove the waste (metabolic waste) produced from chemical reactions inside their body
What is the difference between breathing and respiration?
Breathing - inhaling oxygen and exhaling carbon dioxide
Respiration - breaking down food to produce energy
