This part carries "food" from the leaves to the rest of the tree.

This protects the tree from injury caused by insects, animals, humans, disease, and fire.

These anchor the tree in the ground and absorb water and nutrients from the soil.

These use sunlight, carbon dioxide, and water to create food for the tree.

This green pigment helps leaves absorb the sunlight needed to perform photosynthesis.

This byproduct of photosynthesis is beneficial to humans and the environment.

Photosynthesis is the process of converting
