Do plant take in oxygen and give out carbon dioxide at night?

Answer 1

Plants take in carbon dioxide and give off oxygen during the day but the do the opposite at night. Plants take in a small amount of oxygen so you don't have anything to worry about if you have them in your bedroom.

Answer 2

Basically plants like most living things breathe oxygen, but during day they take up more CO2 and negligible amount of O2 to prepare food.....But during night, they do not prepare food due to absence of sunlight, so do not require CO2 and take in more O2.....

Answer 3

No, plants don't produce oxygen in night, because there is no sun light and sun light is essential for photosynthesis. therefore, instead of producing oxygen, they consume oxygen and produce carbondioxide.

Answer 4

Yes.

In addition to performing photosynthesis which is fixation of carbon to produce sugars (food), plants also carry on respiration (just like animals do). To do this they use some of the food (sugars) they created by photosynthesis and oxidize it (using the same oxygen they produce by photosynthesis). This provides energy to perform the myriad of energy-intensive functions in the plant.

One example is that plants build strong fibers in order to grow tall and withstand the wind. To accomplish this, they create cellulose and lignin which are polysaccharides (complex sugars). This is an energy intensive process and the energy comes from respiration. Some plants carry on such functions mainly at night.

Answer 5

Yes a plant can make oxygen at night but only produces a gas in the day. That is what i remember my sciece techer telling me so please do not blamae me if this answer is wrong because i only tried but i do know that plants make oxygen at night!!

Answer 6

plants do not take in oxygen they take in carbon dioxide, and yes the do it at night.

Answer 7

Plants will stay active for a few hours after the sun is gone. So yes they can but only for a little while

Answer 8

yes
