1 What is the difference between endoskeletons ... - SS1 Biology Tissues and Supporting Systems Question

Endoskeletons and exoskeletons are two distinct types of skeletal systems found in different organisms. An endoskeleton is an internal skeletal framework present within the body of an organism. It provides structural support, protects vital organs, and serves as an attachment point for muscles. Endoskeletons are commonly found in vertebrates, including humans, and are composed of bones or cartilage. The flexibility and adaptability of endoskeletons allow for efficient movement and growth.

 

On the other hand, an exoskeleton is an external skeletal structure that surrounds the body of an organism. It functions as a protective shield against predators, physical damage, and desiccation. Exoskeletons are typically composed of a tough and rigid material such as chitin, which provides strength and stability. Organisms with exoskeletons, such as insects, crustaceans, and some mollusks, undergo molting or shedding of their exoskeletons to accommodate growth.
