Concept:Plants store excess glucose as
Starch, a polysaccharide that acts as the internal energy reserve.
Explanation:Starch is a complex carbohydrate composed of many glucose units joined by glycosidic bonds.
It is synthesised during photosynthesis and stored mainly in plastids.
Being insoluble in water, starch remains stored without disturbing the cell's osmotic balance.
When energy is required, starch is broken down into glucose for cellular respiration.
Glycogen is the energy reserve in animals and fungi, not in plants.
Glucose is a simple sugar that serves as an immediate energy source.
Sucrose is a disaccharide mainly used for energy transport in plants.
Hence, the internal energy reserve in plants is starch.
Answer:Option B:
Starch
