When a plant is not strong enough to support its own weight, what is most
likely the problem?
o
a. the plant is producing too many polysaccharides.
o
b. the plant needs more monosaccharides to add strength.
o
c. the plant does not have enough starch.
o
d. the plant is not producing enough cellulose.

When a plant is not strong enough to support its own weight, the problem is the plant is not producing enough cellulose.

Option D

A plant is unable to support itself when it is not producing enough cellulose. Cellulose is a biochemical present in all living beings. In the case of plants, cellulose is a critical component that is required by plants for their strength. Cells of a plant are surrounded by cell walls which are made tough due to the presence of cellulose in them.

Hence, the different parts of a plant such as a stem, branches, leaves, etc, are strong in nature. When the amount of cellulose in a plant is less than it should be, the plant fails to support itself and starts bending.

b is the correct answer
