Plants grow over time by balancing two chemical reactions: photosynthesis and cellular respiration. plants use the products of photosynthesis as the reactants of cellular respiration.
photosynthesis: 6co2 + 6h2o + energy c6h12o6 + 6o2
which is the chemical equation representing cellular respiration?
a. 6h2o + energy c6h12o6 + 6o2
b. c6h12o6 + 6o2 6co2 + energy
c. 6co2 + 6h2o + energy c6h12o6 + 6o2
d. c6h12o6 + 6o2 6co2 + 6h2o + energy

The answer to that I think would be D because:

A is wrong because it doesn't make sense the way the order it is in,

B doesn't make sense because it is in the wrong order,  and

C says the same exact thing that photosynthesis says which would mean that it is representing the photosynthesis equation not the chemical equation for cellular respiration.

Also it is D because D shows the correct way that the chemical equation representing cellular respiration is supposed to be in.

Hope this helped!
