Question

Why do we say that the cockroaches have exoskeleton?

• A. Because the skeleton has scales
• B. Because the skeleton is flexible
• C. Because the skeleton is on the outside
• D. Because the body is brown

Answer 1

The correct option is C

Because the skeleton is on the outside

Cockroaches have exoskeleton made up of chitin.

When a skeleton is on the outside, it is called an exoskeleton. The exoskeleton supports and protects the roach’s insides. Because it is hard, the exoskeleton cannot grow. The skeleton is made of a hard substance called chitin.
