Solution
The correct option is D Fibroblasts
Fibroblasts are large, flat, branching cells which appear spindle-shaped in a side view. In mature tissue they are quiescent. After injury, they begin to form new fibers. Under the electron microscope, the activated fibroblast shows the extensive rough ER needed for the synthesis of collagen and elastin fibers. Proteoglycans, a chief component of the ground substances of connective tissues are also synthesized by these cells. Fibroblasts have large, oval and faint staining nuclei with one or two conspicuous nucleoli.
Therefore, the correct answer is option D.
