Chitin

Real World Example

Imagine trying to protect your phone with a case that's both sturdy and lightweight. Just like how a phone case shields your device from damage while being easy to carry around, chitin serves as a protective barrier for insects and fungi, offering durability without adding much weight. In this analogy, the chitin is like the phone case; it provides a tough, resilient cover (like the exoskeleton or cell wall) that safeguards the delicate insides (insect organs or fungal cells) from external harm, much like how a case protects the phone from drops and scratches.
