Detailed explanation-1: -The principal cell of connective tissues is the fibroblast, an immature connective tissue cell that has not yet differentiated. This cell makes the fibers found in nearly all of the connective tissues. Fibroblasts are motile, able to carry out mitosis, and can synthesize whichever connective tissue is needed.

Detailed explanation-2: -The ‘ground substance’ of extracellular matrix is an amorphous gelatinous material. It is transparent, colourless, and fills the spaces between fibres and cells. It actually consists of large molecules called glycosoaminoglycans (GAGs) which link together to form even larger molecules called proteoglycans.

Detailed explanation-3: -In connective tissue, the extracellular matrix consists of D) protein fibers and ground substance. Fibers that can be found in the extracellular matrix include collagen, reticular fibers, and elastic fibers. Ground substance is a material that occupies the spaces between the cells and fibers of connective tissue.
