Scientists estimate a safe oxygen consumption of 50 liters per hour for a human. Meanwhile, a leaf gives off about five milliliters of oxygen per hour. A person would need to be in a room with about ten thousand leaves. About 300 to 500 plants would produce the right amount of oxygen.
They photosynthesise to produce glucose, and then respire to convert that glucose into energy. During the day, plants give out more oxygen, and during the night, plants give out more carbon dioxide. Plants have two types of respiration arobic and anerobic. Plants do not breathe like humans, although they respire. This is when they absorb oxygen from the air around them and in return, release Carbon Dioxide. This is different from photosynthesis where they release oxygen and take in carbon dioxide.
