Answer:

B, The rigid cell wall of green plants is composed of cellulose.

Explanation:

Cellulose is an organic compound, classified as a carbohydrate, that makes up a tough cell wall surrounding plant cells. It is a polysaccharide with beta 1, 4 d-glucose linkages (very strong bonds) making it very difficult to degrade by hydrolysis and enzymatic action. Through that, cellulose serves an important structural component because it provides roots and stems their rigidity, toughness and protection from microbial degradation.
