GENERAL HISTOLOGY

Detailed explanation-1: -Connective tissues are composed of a matrix consisting of living cells and a non-living substance, called the ground substance. The ground substance is composed of an organic substance (usually a protein) and an inorganic substance (usually a mineral or water).

Detailed explanation-2: -The ground substance of connective tissues is made up of GAGs or glucosaminoglycans which are basically complexes of proteins and carbohydrates. They were formerly known as mucopolysaccharides. So, the correct answer is ‘Mucopolysaccharides’.

Detailed explanation-3: -Connective tissue consists of cells, fibers, and ground substance. The ground substance consisting of glycoproteins and water, and the insoluble protein fibers collectively are called matrix.

Detailed explanation-4: -Connective tissue consists of cells embedded in an extracellular matrix. The matrix, in turn, consists of fibers and ground substance.

Detailed explanation-5: -Ground substance is primarily composed of water and large organic molecules, such as glycosaminoglycans (GAGs), proteoglycans, and glycoproteins. GAGs are polysaccharides that trap water, giving the ground substance a gel-like texture.
