Sugar is a simple molecule used by the plant for energy, starch is a complex sugar molecule used for long term energy storage. predict which part of the might be used for starch storage and give an explanation of why in this location

starch is stored in a special cell organelle called amyloplasts. glucose is energy source for plant but for storage starch is preferred. it stores in stroma and when needed converts starch into glucose.

the amyloplasts contain all the basic properties and materials like enzyme and pH which are needed to do both the process efficiently (polymerization into starch and breakdown to glucose) and also the storage capacity so they are used as storage.

looks like the answer is     c     to me!
