Solution

The correct option is E I and III only
Cellulose forms an integral part of the cell wall which provides strength and rigidity to the cell. It helps to maintain the structural integrity of a particular cell. Cellulose is a complex polysaccharide which is made up of β(1→4) linked D-glucose units.
Starch is the important food reserve for the plants. The excess amount of glucose synthesized during dark reaction of photosynthesis is stored in food vacuoles of the plant which it again converted into a usable form of glucose in case of unfavorable conditions. It is a complex polysaccharide formed by 1,4-alpha linkage between two glucose unit.
So, the correct answer is option E.
