Detailed explanation-1: -(adenosine triphosphate) chemical found in most living cells and used for energy. Used by the majority of plants, it involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become a sugar called glucose.

Detailed explanation-2: -Carbohydrates. Quantitatively, the most important of nutrients are the carbohydrates synthesized by plants, since they provide most of the energy utilized by the animal kingdom.

Detailed explanation-3: -Glucose is stored as polymeric glucan, in animals as glycogen and in plants as starch.

Detailed explanation-4: -Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source.

Detailed explanation-5: -Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules. ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups.
