Question
Write two main functions of carbohydrate in plants.
✓

Answer

(i) Structural material for plant cell walls : For example, the polysaccharide cellulose acts as the chief structural material of the plant cell wall.
(ii) Bio-fuels : Carbohydrates such as glucose, fructose, sugar, starch and glycogen acts as bio-fuels and hence provide energy for the functioning of the living systems. For examples,
$\underset {\text {Glucose}}{C_6 H_{12} O_6}+6 O_2 \longrightarrow$$6 CO _2+6 H _2 O +2880 kJ$
