it doesn't it takes in the carbon dioxide and then turns that into the oxygen
==============
Actually, at night plants consume oxygen, but only a small fraction, compared to the amount they produce during the day.
Yes. Plants create oxygen through the process of photosynthesis. The plants take in carbon dioxide that animals and humans breathe, water, and minerals in the soil and produce oxygen and glucose.
No. Oxygen is produced as a waste product of photosynthesis and is excreted from the plant as it is not needed by the plant.
sugar and oxygen
No, they use carbon dioxide to make oxygen.
oxygen
The plant use at day time is carbon dioxide. The plant use at night time is oxygen.
no i dont think so they make oxygen so i dont think they need it
photosynthesis
Oxygen is a good example.
Yes, the burning candle will use up the oxygen inside the bell jar, leading to a decrease in the oxygen levels. However, plants also require oxygen for respiration, so if the oxygen levels drop too low, both the plant and the candle may eventually be deprived of oxygen and stop burning or respiring, rather than the plant being burned by the candle.
The easiest way is to use an aquatic plant (one that grows underwater). In sunlight this will release bubbles - collect the bubbles in an upturned (water filled) jar placed over the plant. Once you have collected the gas use the oxygen test (relight a smoldering taper) on the gas to see if it is oxygen.
Plants perform photosynthesis then use oxygen for cellular respiration.
