in night plants respire by taking oxygen and releasing CO2 in air due to unavailability of sunlight. thus, plants undergo dark reaction at night as it works total opposite than in day..

Answer:
no plants do not do dark reaction at night.
Explanation:
in dark phase, CO2 is reduced to glucose by means of energy(ATP) and reducing power(NADPH) produced during light reaction.
This process occurs in the stroma of chloroplast in this phase excitation of CO2 .
Dark reaction does not mean that it takes place in dark it simply means that dark reaction does not need light energy. Time gap between the two is less than one thousand second..
hopefully this will help you.
