Understand the term 'endoskeleton': An endoskeleton is an internal support structure of an organism, typically composed of bone and cartilage.
Differentiate between endoskeleton and exoskeleton: An exoskeleton is an external skeleton that supports and protects an animal's body, unlike an endoskeleton which is internal.
Identify the primary function of an endoskeleton: It provides structural support, facilitates movement by anchoring muscles, and protects internal organs.
Consider the composition of an endoskeleton: It is usually made up of bones and cartilage, which are living tissues that can grow and repair themselves.
Recognize the types of organisms with endoskeletons: Endoskeletons are characteristic of vertebrates, such as mammals, birds, reptiles, amphibians, and fish.
