Identify the specialized connective tissue on the basis of following features

A) Hard and non-pliable ground substance

B) Serve weight bearing function

C) Site of production of blood cells

Bone has a very hard matrix due to calcium salts. Bones support and protect softer tissues and organs. The bone cells (osteocytes) are present in the spaces called lacunae. Limb bones, such as the long bones of the legs, serve weight-bearing functions. They also interact with skeletal muscles attached to them to bring about movements. The bone marrow in some bones is the site of production of blood cells.
