Glycogen is to Animal Cells as ________ is to Plant

Question

Glycogen is to animal cells as ________ is to plant cells.
A)lipid
B)cellulose
C)starch
D)protein
E)sugar

Accepted Answer

Glycogen is the carbohydrate storage molecule in animal cells, while starch fulfills the same role in plant cells. Cellulose is a type of carbohydrate, but it forms the structural component of plant cell walls rather than serving as a storage molecule. Lipids and proteins are biomolecules with various functions, but they are not directly analogous to glycogen or starch. Sugars are an important type of carbohydrate, but they do not serve as long-term storage molecules like glycogen or starch.
