Question
Write two main functions of carbohydrates in plants.
Advertisements
Solution 1
Two main functions of carbohydrates in plants are:
- Polysaccharides such as starch serve as storage molecules.
- Cellulose, a polysaccharide, is used to build the cell wall.
Solution 2
Two major functions of carbohydrates in plants are the following:
- Structural material for plant cell walls: The polysaccharide cellulose acts as the chief structural material of the plant cell walls.
- Reserve food material: The polysaccharide starch is the major reserve food material in the plants. It is stored in seeds and acts as the reserve food material for the tiny plant till it is capable of making its own food by photosynthesis.
