What is the difference between cartilage and bones?

Cartilage and bone are stiff tissues which form the
essential structural form of animals. Though both of them serve many common functions
they are also different in many ways.

Cartilage consists of
cells called chondrocyte, and materials produced by the chondrocytes called collagen and
elastin fibers. Bones are made of a bodily tissue called osseous tissue and instead of
collagen as in cartilage bones are made up of calcium compounds. Bones also contain
centers for production of cells and storage of minerals. Cartilage is the slowest tissue
to grow and if damaged repairs itself at the slowest rate.
