In what polysaccharide form do plants store glucose to be available later as an energy source?
A
Glycogen
B
Cellulose
C
Protein
D
Fatty acids
E
Starch
Verified step by step guidance1
Understand that polysaccharides are long chains of monosaccharides linked together. In plants, these are primarily used for energy storage or structural purposes.
Identify the role of each option: Glycogen is a storage form of glucose in animals, not plants. Cellulose is a structural component in plant cell walls, not primarily for energy storage.
Recognize that proteins and fatty acids are not polysaccharides. Proteins are made of amino acids, and fatty acids are components of lipids.
Recall that starch is the primary storage form of glucose in plants. It is a polysaccharide composed of amylose and amylopectin.
Conclude that starch is the correct answer, as it is the polysaccharide form in which plants store glucose for later energy use.
