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

1. What is the related biological process?Integral to the Compartmentalization Of Decay In Trees (CODIT) theory
2. What are tyloses in trees?Tyloses are balloon‑like cells that grow into the tubes of a tree’s water system, called xylem vessels. They act like tiny plugs to stop damage from spreading.
3. Why do trees make tyloses?Trees make tyloses to keep insects, fungi, and air bubbles from moving through their water tubes. This helps the tree stay strong and healthy.

Xylem Vessels/Tracheids: The primary water-conducting cells in woody plants, forming continuous tubes for transport.
Parenchyma: Fundamental plant cells with diverse metabolic functions, including storage and wound response.
Embolism: A blockage in a xylem vessel, often caused by an air bubble, which disrupts water transport.
Heartwood: The non-living, central wood of a tree, providing structural support and often exhibiting increased decay resistance.
