Solution
The correct option is D 250 Microfibrils are composed of glycoproteins and cellulose. The cellulose microfibrils are laid present in the primary cell wall. An aggregation of 250 microfibrils constitutes a fibril of cellulose. On absorption of water, the volume of cell increases and the existing microfibrils separate and new ones are formed to help increase cell strength.
