उत्तर
The internal energy (cellular energy) reserve in autotrophs is starch.
Explanation:
Starch is the primary internal energy-storage molecule in autotrophs such as green plants and algae. During photosynthesis, autotrophs produce glucose as their main food source. Because glucose is highly soluble in water, any excess sugar that is not used immediately for energy is converted into insoluble starch and stored in plant tissues for later use when the organism needs it.
