A bone is a hard connective tissue, while cartilage is soft connective tissue. Bones form the skeletal structure of the body, whereas cartilage is present in nose, ear, ribs, larynx, and joints and also act as a shock absorber in these joints.
Bones protect against the mechanical damage and supports the movement of the body, provide shape to the body. And as cartilage being soft they are usually found along the respiratory tract, between the joints and in other flexible parts of the body.
Our body’s skeletal system is made up of bones and cartilage. They provide proper shape, rigidity to the body. Both protect the delicate organs from internal and external shock also. They are also responsible for movement and locomotion of the body, along with the flexibility. In this content, we will take up the important differences between both along with their functions.

Meaning Bones are the complex structure, made up of connective tissues which are hard and are helpful in providing protection, shape to the body. Cartilage is the simple structure, made up of connective tissue which is soft and are useful in providing flexibility to the joints and also protect from the external and internal shocks.
Features They are rigid, non-flexible, and tough. They are flexible and are soft-elastic.
Bones grow in both directions (bidirectional). Cartilage grows in single direction (unidirectional).
Haversian system and Volkmann's canals are present. Haversian system and Volkmann's canals are absent.
Bone marrow is present (it is a kind of haematopoietic tissue from which all blood cells are made). Bone marrow is absent.
Lacunae possess canaliculi where each lacuna consist of only one cell (osteocyte). Lacunae do not possess canaliculi, and each lacuna has two-three chondrocytes.
These are active participants of blood supply. They are not the participants in blood supply, except in perichondrium.
Matrix consist of the protein called ossein and can be both organic and inorganic. They occur in lamellae and are vascular. They have the deposit of calcium salts largely of calcium phosphate. The matrix consists of the protein called chondrin, and they are organic. In cartilage, a matrix is said to be as homogenous mass without lamellae. They do not possess calcium salts.
Bones cells are also known as Osteocytes. Cartilage cells are also known as Chondrocytes.
Bones are hard due to the deposition of phosphates and carbonates of calcium in the matrix. Cartilage is soft, except the calcified cartilage and matrix is made up of proteins and sugars.
They are responsible for the formation of the skeletal system, which gives the shape to the body. Cartilage is found in ear, nose, larynx and trachea.
Types Two types
1. Compact bone.
2.Spongy bone.
Three types
1. Fibrocartilage.
2. Elastic cartilage.
3. Hyaline cartilage.
1. They are hard .
2. Bones form the skeletal structure of the body .
3. Bones protect against the mechanical damage . They supports the movement of the body, provide shape to the body.
4. Bones grow in both directions (bidirectional).
5. Bone marrow is present .
Cartilage :-
1. It is soft .
2. Cartilage is present in nose, ear, ribs, larynx etc. .
3. Cartilage being soft they are usually found along the respiratory tract, between the joints and in other flexible parts of the body.
4. Cartilage grows in single direction (unidirectional) .
5. Bone marrow is absent .
