- The main support of the tree. ____________________
- The protective outer layer of the truck. ____________________
- The structures that obtain food and water from the soil, store energy, provide support for the plant. ____________________
- The upper parts of the tree, where the branches and leaves are located. ____________________
- The core of the trunk that contains very strong, dead tissue that supports the tree. ___________________
- Woody parts of the tree that grow from the trunk. ____________________
- A single layer of living cells in the trunk that is located between the sapwood and the inner bark. It produces the sapwood and the inner bark. ____________________
- The layers of wood just outside the heartwood. ____________________
- The layer of the trunk through which the tree’s food flows-it is located between the outer bark and the cambium. When this short-lived layer dies, it is called cork. ____________________
