QUESTION 14.3

Write two main functions of carbohydrates in plants.

Answer 1

Functions of carbohydrates in Plants:
(i) Cell walls of plants are made up of cellulose and hemicellulose and both of them are polysaccharides. This structure provides rigidity to the plant cell. Therefore, carbohydrates support the growth of the plant.

(ii) After the production of glucose during photosynthesis, the glucose is converted to starch. Starch acts as the stored nutrient in plants that are used by the plant when it is unable to perform photosynthesis. This proves that carbohydrates support the biochemical processes inside the plant cells.
