Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the model name?CODIT (Compartmentalization Of Trees In Decay)
2. What is the primary developer?Alex Shigo, plant pathologist
3. How do trees make walls to stop decay?Trees change the chemicals in the wood, grow stronger cells, seal off the inside, and grow new wood around the wound. These steps create four different walls that act like a protective fence.
4. What are the four walls in the CODIT model?Wall 1 changes the wood’s chemistry to make it less tasty for germs. Wall 2 makes the wood cells thicker and harder. Wall 3 keeps germs from getting into the inner parts of the tree. Wall 4 is new wood that the tree grows to cover the wound.

Cambium: A layer of actively dividing cells in trees responsible for secondary growth, producing new wood and bark.
Vascular Tissues: The tissues (xylem and phloem) in plants that transport water, minerals, and nutrients throughout the plant.
Silviculture: The control and cultivation of forests, including the management of trees for timber production and ecological health.
