The carbon taken in by plants during photosynthesis stored in "plant structures".
Option: B
Explanation:
The carbon drawn in by photosynthesis plants is contained in the structures of the plants in the form of polysaccharides such as starch, cellulose, etc. When plant absorbs carbon in the context of glucose using photosynthesis, plants use a certain amount of glucose to generate energy for their day-to-day activities, while the plant retains the excess amount of glucose for potential use in special organelles understood as amyloplasts and stored in roots, stems, tubers, etc like various structures of the plant.
