Bone is a skeletal connective tissue and has a tough matrix containing collagen fibres and salts of calcium and magnesium. The cells of the tissue are called osteocytes. Provides support to the body and a place for attachment of muscles.

Cartilage:

Cartilage is a semi rigid connective tissue containing many fibres of collagen. The cells are called chondrocytes. They are present between the bones and protect the joints.
