Explain the role of the leaves, stem and roots of plants.
Leaves-- collects sunlight and gases from the air to make food for the plant
Stems-- hold up leaves and carry water and nutrients throughout a plant

What is a habitat?
What happens if a habitat changes?
A habitat is a place where a plant or animal lives.
