Plants need to photozynthesis during day does not enable them to respire.
Living things that do not respire 24/7 are soon dead things. Respiration occurs in all living cells to provide energy. in plants people often confuse photosynthesis with respiration. Photosynthesis is the extraction of carbon dioxide from the air using light energy to create oxygen and carbon, The carbon is changed into sugars and cellulose by the plant. The plant's respiration (using the sugars to create energy) goes on day and night.
