Final answer:
A growing bone is porous, less dense, and actively undergoing growth, while a mature bone is compact, solid, and has completed its growth phase.
Step-by-step explanation:
A growing bone and a mature bone differ in their structure and composition.
A growing bone, also known as an immature bone, is characterized by a porous and less dense structure compared to a mature bone. It is also actively undergoing growth and development, which involves the process of bone modeling and remodeling.
In contrast, a mature bone has a more compact and solid structure. It has completed its growth phase and reached its final shape and size. The cells responsible for bone remodeling, such as osteoblasts and osteoclasts, are less active in a mature bone.
