What is Movement?
The action of MUSCLES in animals and slow growth in plants
What are the eight life processes?
.Movement
.Respiration

What is Respiration?
Release of ENERGY from food requires OXYGEN
What is Sensitivity (stimuli)?
Responding to their surrounding or like a plant responding to the stimulus of light.
What is Growth and Development?
Increase in size and complexity using the materials from their food
