Cellulose
C
Glycogen
D
Chitin
Verified step by step guidance

Understand the question: The problem is asking for the name of the energy-storage polysaccharide in plants. Polysaccharides are long chains of monosaccharides (sugar molecules) linked together, and they serve various functions such as energy storage or structural support.
Review the options: The given options are Starch, Cellulose, Glycogen, and Chitin. Each of these is a polysaccharide, but they have different roles and are found in different organisms.
Recall the function of each polysaccharide: Starch is the primary energy-storage polysaccharide in plants. Cellulose is a structural polysaccharide found in plant cell walls. Glycogen is the energy-storage polysaccharide in animals and fungi. Chitin is a structural polysaccharide found in the exoskeletons of arthropods and the cell walls of fungi.
Focus on plants: Since the question specifies plants and energy storage, eliminate options that do not fit this context (e.g., Glycogen and Chitin). Cellulose is structural, not for energy storage, so it is also not the correct answer.
Conclude: Based on the above reasoning, the energy-storage polysaccharide in plants is Starch.
