Composition of Exoskeleton in Arthropods
The exoskeleton of arthropods, which includes insects, arachnids, and crustaceans, is primarily made of chitin. Here’s a detailed explanation:
What is Chitin?
- Chitin is a long-chain polymer of N-acetylglucosamine, a derivative of glucose.
- It is a tough, flexible, and lightweight material, providing both protection and structural support.
Function of Chitin in Arthropods
- Protection: The exoskeleton acts as a barrier against physical damage and predation.
- Water Retention: It helps prevent water loss, crucial for terrestrial arthropods.
- Muscle Attachment: The rigid structure allows muscles to attach efficiently, facilitating movement.
Comparison with Other Options
- Cellulose: Found in plants, it is not present in arthropods.
- Glucosamine: While it is a component of chitin, it is not a structural material on its own.
- Cutin: This is a polymer found in the protective layer of plant leaves and stems, not in arthropods.
Conclusion
The unique properties of chitin make it an ideal material for the exoskeleton of arthropods, allowing them to thrive in various environments. This is why the correct answer to the composition of the exoskeleton in arthropods is option 'B', chitin.
