Best Answer: yes, plants use oxygen at night... However, plants can't produce glucose, carbohydrates and oxygen without light. To get through the night, most plants reverse the process of photosynthesis and breathe, like you and I, by burning carbohydrates and oxygen while producing carbon dioxide and water.
Photosynthesis from plants use carbon dioxide, sunlight, and water and a byproduct is oxygen. Before humans existed, the earth existed for millions of years creating an enormous supply of oxygen. Organisms and plants created a balance of oxygen and CO2. The Earth's net supply of oxygen comes from phytoplankton. Plants produce oxygen but use up what they make by producing carbon dioxide at night and when they are burned or decompose, so you see, the only thing that keeps us breathing is the tiny phytoplankton in the sea.
