Question

Which type of connective tissue has a mineralized different matrix?

a. loose connective tissue

b. fibrous connective tissue

c. cartilage

d. bone

Short answer

The correct answer is (d) bone

The bone as one of the connective tissues has a mineralized different matrix.

Step-by-step solution

Step1. Introduction 

Connective tissue is a tissue that not just supports, and protects, but also provides structure to other tissues and organs of an organism's body. There are four classes of connective tissues.

Explanation for correct answer  

d. bone

Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts—mostly calcium salts—that give the tissue hardness. Without adequate organic material in the matrix, the tissue breaks; without adequate inorganic material in the matrix, the tissue bends.

Explanation For Incorrect options 

a. loose connective tissue

Loose (areolar) connective tissue type of connective tissue with small amounts of cells, matrix, and fibers; found around blood vessels.

b. fibrous connective tissue

Fibrous connective tissue type of connective tissue with a high concentration of fibers. Fibrous connective tissue or dense connective tissue has most fibers as it is made up ofbundle of collagen fibers present parallel . These are present in tendons, ligaments, and dermis.

c. cartilage

Cartilage type of connective tissue with a large amount of ground substance matrix, cells called chondrocytes, and some amount of fibers
