Item ME036003: To make its trunk, branches, and leaves, a tree makes glucose from carbon dioxide and water and then uses the glucose molecules to make carbohydrate polymers.
What does a tree do to make its trunk, branches, and leaves?
Tree. Photo by Jean Flanagan.
- The cells that make up the tree divide creating new matter that the tree uses to build its trunk, branches, and leaves.
- The tree takes in minerals and water from the soil. Its trunk, branches, and leaves are made up of these minerals and water.
- The tree makes glucose from carbon dioxide and water. Its trunk, branches and leaves are made up of these glucose molecules.
- The tree makes glucose from carbon dioxide and water. It then uses these glucose molecules to make carbohydrate polymers that become part of its trunk, branches, and leaves.
