A Correct answer
Explanation

Xyloglucans are the main hemicellulosic polysaccharides found in the primary cell walls of dicots and non-graminaceous monocots. Xyloglucan and cellulose together make up about two-thirds of the dry weight of primary cell walls and is the major tension bearing components of the matrix.
