Differentiate between exoskeleton and endoskeleton.

Hint: The body of a living organism consists of two parts namely, Endoskeleton and Exoskeleton. A complex network of several organs constitutes the skeletal system.

Complete answer:
Endoskeleton refers to the hard structure which is present as an inside support system. The structure is developed from an endodermal layer and is living in nature. Bone, cartilage, etc. are some of the examples of endoskeleton. On the other hand, exoskeleton is the hard structure found on the outer side of the body. It provides protection to muscles and various other soft tissues. It is formed from the ectodermal layer and moreover, it is non-living in nature. Horns, scales, feathers, hair, etc. are some examples of exoskeleton.



Note: The skeletal system serves as a support system for the body. It provides shape to the body and helps in its movement. It forms blood cells and helps in storage of minerals. Moreover, it also protects organs from injury. The skeletal system is also referred to as the musculoskeletal system.
