Are plants produce oxygen in the morning and carbon dioxide at night??

Answer 1

That's a fairly common misconception. Overall, the net flow is close to that, but there are actually two processes going on.

During daylight hours, the plant photosynthesises. It uses the sunlight to make food for itself, and converts carbon dioxide into the air into (essentially) carbon and oxygen. The carbon it keeps as starch which it uses as energy and to grow. The oxygen is released into the air.

At the same time, and permanently, it also respires. This is the reverse process. carbon and wather are used, in conjunction with oxygen, to release energy. The waste prouct of this is carbon dioxide.

At night, the plants cannot photosynthesise, and so only respiration occurs. thus, in the night, the plant only produces carbon dioxide, but in the day it also prduces oxygen.

Incidentally, trees aren't the biggest producers of the world's oxygen. That comes from phytoplankton in the oceans.

Answer 2

Indoor plants actually "consume" carbon dioxide and emit oxygen. Therefore you're apt to breath better (not worse) when you sleep with plants. You would have to have a lot of plants, however, before the oxygen level in your room would be effected to the point you'd notice it. The amount of water to give a plant depends completely on the type of plant. Many just need a little water once a week. As a general rule you just need to water them when the soil is dry to the touch. Cactus obviously need very little water but sandy soil. If you let a plant get really dry and you water it a lot, the water will run right through, onto your table. A better option in that case is to water just a little, then come back 15 minutes later and water more. The dampened soil will actually absorb much more water the second time.

Answer 3

Plants - just like all other living organisms - require Oxygen as a means for generating ATPs (Adenosine TriPhosphate), the energy currency of the cell. So they take in Oxygen and exhale Carbon Dioxide. This is a continuous process. However, during the daytime, in sunlight, plants synthesize their own glucose utilizing the sun's energy using chlorophyll, which is the green pigment of plants. As a by product of this reaction, Oxygen is produced which is given out. So even though plants are taking in Oxygen, the quantity given out is far greater than the amount taken in! During the night, since there is no sunlight, the process of glucose synthesis stops. So no oxygen is produced. Respiration continues, oxygen is taken in continuously, but none is given out!

Answer 4

No, plants take in carbon dioxide and produce oxygen.

Answer 5

1) In daytime, plants photo-synthesize in sun-light, releasing oxygen in the process.
2) Plants breathe, like most other organisms. In respiration process, they release CO2, 24-hrs a day, not only in the night.

Answer 6

yes this is true.This is because of the absence of sunlight in night owing to which plants cannot perform photosynthesis and so follow the process of photo-respiration which is nothing but the process of releasing carbon dioxide.

Answer 7

no plants obsorb carbon dioxide and excrete oxegen its like an elephant eating peanuts(carbon dioxide) And "leaving behind" unmentionables (Oxygen)

Answer 8

hey everybody:
-During daytime, plants may do photosynthesis and abdorb CO2 and release O2 or it can do normal breathing.
-In darkness plants will only do normal breathing that's why you should not put a plant in your room at night.

Answer 9

plants breathe in co2 and exhale oxygen, just like we breathe in oxygen and breathe out co2

this isn't on a daily/nightly schedule...this is constantly
