Acting as genetic material

Catalyzing metabolic reactions

Verified step by step guidance

Understand the role of polysaccharides in plants. Polysaccharides are long chains of monosaccharides linked by glycosidic bonds, and they serve specific biological functions in plants.

Identify the two main types of polysaccharides in plants: starch and cellulose. Starch is used for energy storage, while cellulose provides structural support in the cell walls.

Eliminate incorrect options: Polysaccharides do not transport oxygen (this is the role of hemoglobin in animals), act as genetic material (this is the role of DNA and RNA), or catalyze metabolic reactions (this is the role of enzymes).

Focus on the correct functions: Starch stores energy in the form of glucose units that can be broken down when needed, and cellulose forms rigid structures in plant cell walls, giving plants their shape and strength.

Conclude that the best description of the main functions of polysaccharides in plants is 'Energy storage and structural support.'
