dear student,
The difference between bones and cartilage are-
Bones         Cartilage
Types: Bones are classified into long, short, flat, irregular, sesamoid and sutural bones. Types of cartilage include hyaline cartilage, fibrocartilage and elastic cartilage.
Function: Bones perform a variety of functions like protecting the body against mechanical damage, assisting in the movement of the body, providing a framework and shape for the body, storing minerals and producing red blood and white blood cells. The main function of cartilage tissue include reducing friction at the joints, supporting tracheal and bronchial tubes, acting as shock absorbers between vertebrae, and maintaining the shape and flexibility of ear, nose and so on.
Structure: Bone or osseous tissue is made up of osteoblasts (progenitor cells), osteocytes (mature bone cells), and osteoclasts (large cells that breakdown bone tissue for growth and repair), and bone lining cells (that regulate the movement of calcium) Cartilage comprises of chondroblasts, which are precursor cells, chondrocytes, and dense matrix comprising of collagen and elastic fibres, in which the mature chondrocyte cells are embedded.
