Where is the carbon taken in by plants during photosynthesis stored?
a. the ground
b. plant structures
c. the air
d. all of the abovewhere is the carbon taken in by plants during photosynthesis stored?
d. all of the above

The answer to this problem is B

The correct answer is option b) plant structures.

The carbon which is taken in by the plants for photosynthesis is stored in the plant structures in the form of polysaccharides like starch, cellulose etc. When plant fixes carbon in the form of glucose with the help of photosynthesis, some amount of glucose is used by the plants for the production of energy for its day to day activities  while the excess amount of glucose is stored by the plant for future use in special organelles known as amyloplasts. The photosynthate in the amyloplasts is then stored in various structures like roots, stems, tubers etc of the plant. Apart from this, some amount of glucose is also used by plant for making cellular structures like cellulose which is present in the cell wall of a plant cell. Cellulose is a very rigid polysaccharide and therefore it serves the purpose of providing mechanical support and protection to the plant.

i think its the first one

it's c. (to reduce the greenhouse effect/carbon gasses)
