Question

How many microfibrils combine to form a fibril of cellulose?

• A. 50
• B. 100
• C. 200
• D. 250

Answer 1

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.

So, the correct answer is option D.
