Given:
The solution decreased by 
ounces every hour for 5 hours.
Remaining solution at the end of the experiment = 
ounces.

3. Composition of Plant cell walls is that they are primarily made of cellulose. Cellulose fibers are linear long polymers of around 100 molecules of glucose. These fibers cluster into bundles, known as or called microfibrils. In plants the microtubule cytoskeleton are present, and there function is that they directs the orientation of cell wall as in which orientation cellulose is deposited in the cell wall.
