Plants get sugar from dark reaction of Photosynthesis. Then they use this sugar in cellular respiration and release #CO_2#, water and energy.

Explanation:

Dark reactions take place in the stroma of chloroplast. These reactions can occur in the presence or absence of light provided the assimilatory power in the form of #ATP# and #NADPH# which are produced during light reactions. Energy of these compounds is used inthe formation of sugar(carbohydrates) from #CO_2#.
These reactions can be summarized as:

#3CO_2# + #6NADPH# + #9ATP to (CH_2O)_3# + #6NADPH# + #9ADP# +# 9#Pi
