Question

question 5 of 10
a plant is starting to fall over because the plant can no longer support its weight. students want to find out why this is happening. which of the following is a good hypothesis for their experiment?
a. the glucose molecules in the plant are breaking down.
b. the plant is not producing simple sugars to support its structure.
c. the plant is producing cellulose molecules.
d. the polysaccharides in the plant are breaking down.

Explanation:

Cellulose is a polysaccharide that provides structural support to plant cells. If a plant is falling over due to lack of structural support, a likely reason is that cellulose - related processes are disrupted. Glucose is a building - block for cellulose but not directly responsible for structural support in the way cellulose is. Option A is about glucose, not the main structural molecule. Option C and D are too general about polysaccharides without specifying cellulose. The plant not producing cellulose molecules would lead to a lack of structural support and cause it to fall over.

Answer:

B. The plant is not producing cellulose molecules.
