1. What is the etymology and morphology?Named for their lenticular (lens-like) shape, a characteristic used in tree identification
2. Why do trees need lenticels?Trees need lenticels because their bark is mostly solid and blocks air. Lenticels let oxygen reach the inside parts of the tree and let carbon dioxide leave. This keeps the tree's cells alive.
3. How do lenticels help trees breathe?Lenticels let air travel through the bark by creating gaps in the cork. Oxygen moves in, and carbon dioxide moves out, just like breathing. The gaps are made when the bark grows and splits a little.

Periderm: A multilayered protective tissue replacing the epidermis in woody plants, consisting of cork, cork cambium, and secondary cortex.
Suberization: The process by which cell walls become coated with suberin, a waxy substance that makes them impermeable to water and gases.
