Bones are organs that comprise the skeletal system. They are rigid and support the body of vertebrates. Bones are made of living tissue. The cells in bone are called osteocytes. Bones store minerals such as calcium and phosphorus and in the marrow portion of the bones they produce blood cells. They are lightweight, yet strong. Bones contain blood vessels as well as nerves. They store growth factor and in the yellow marrow, they store fatty acid reserves. Cartilage is a connective tissue that is flexible and found in humans and other animals. It is found in the joints (places where bones meet) as well as the knee, the nose and ear and rib cage. Cartilage does not contain blood vessels but gets what it needs by diffusion. Cartilage contains collagen fibers, ground substance and elastin fibers. Cartilage is not as rigid or hard as bone but it is stiffer and less flexible than muscle. The cells in cartilage are called chondrocytes.

Types Bones are either compact or spongy. Bones are classified into long, short, flat, irregular, sesamoid and sutural bones. Hyaline cartilage, fibrocartilage and elastic cartilage. Function Protect the body against mechanical damage, assist in the movement of the body, provid a framework and shape for the body, store minerals, and produce red blood & white blood cells. Reducing friction at joints, supporting the respiratory tract, acting as shock absorbers between weight-bearing bones, and maintaining the shape and flexibility of fleshy appendages. Structure Bones are made up mostly of osteoblasts (progenitor cells), osteocytes (mature bone cells), and osteoclasts (large cells that breakdown bone tissue for growth and repair). A bone is highly vascularized. Cartilages comprise chondroblasts, (precursor cells), chondrocytes, and a dense matrix of collagen and elastic fibers, in which the mature chondrocytes are embedded. Cartilage is avascular. Location Bones make up the majority of the axial and appendicular skeleton. Cartilage is a much softer, more pliable component that is mostly found in between joints of bones (articular cartilage), along the respiratory tract, and in a few other places where flexibility is needed. Fibrous Covering Periostium, rich in sensory nerve endings. Perichondrium (but does not surround articular cartilage).

Cartilage are connective tissues that are soft, flexible and can be bended easily. Cartilage is found between bones in joints. A newborn baby bones consist of cartilage so that the baby is born easily. With time his bones join together forming strong large bones. 

Where as bones are hard and rigid. It supports our skeletal system. Bones protects our organs. Bones can store minerals and also produce blood cells.

Bones and Cartilages belong to the same connective tissue . Bones are hard and porous tissues but cartilages are less hard and is found between the bones

Bones are hard and strong, and cannot be bent or twisted, it will break. Cartillage is soft, and are usually found between bones. It is slightly movable and less strong.
