In a plant cell, the excess of glucose is converted into subunits.
Correct answer: D. Starch
- A. Cellulose
- B. Galactose
- C. Sucrose
- D. Starch
Explanation
In plant cells, excess glucose is primarily stored as starch, which is a polysaccharide. This allows plants to store energy for later use. Starch is the correct answer because it serves as the primary storage form of glucose in plants.Cellulose, on the other hand, is used to construct plant cell walls and does not serve as an energy storage molecule. Galactose is a simple sugar that is not used for storage in plants. Sucrose is used for the transport of sugars but not for long-term storage.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
