The photosynthesis process that occurs at night is called the light-independent reaction, or the calvin cycle. It is a process that utilizes the materials created in the light dependent reaction, ( the process that requires light) and CO2 to produce carbohydrates and oxygen.

In the day! Because photosynthesis occurs more in the day than in the night. And photosynthesis puts CO2 into plants. :)

Where does a plant get the carbon dioxide it needs for the dark reactions of photosynthesis?

From the air around it. During the day, plants absorb oxygen from the air. At night - they absorb carbon dioxide.

When do plants use carbon dioxide night or day?

Plants use carbon dioxide in the daytime as part of photosynthesis which occurs in the chloroplast. They use the CO2 and make sugars. People breath in oxygen and breath out carbon dioxide, plants do the opposite. They breath in carbon dioxide and breath out oxygen.One small "technical" detail that should be mentioned. Plants really don't breath, they respire. People breath.So, at the night, the plant cells respire more than they photosynthesise, so they get rid of more carbon dioxide than oxygen.


What role did plants play in the oxygen cycle?

plants use a prosses of photosynthesis this means that the plants take in carbon dioxide and turn it into oxygen, that is why protecting the plants and envirment is so important. without plants the eath would be full of cabon dioxide making it impossible to live

Do plants exhale carbon di oxide at night?

Carbon dioxide is removed from the atmosphere by photosynthesis in plants and by dissolving in water, especially on the surface of oceans. Plants inhale carbon dioxide


Is carbon dioxide trapped by plants during the night?

Plants don't exactly "trap" carbon dioxide, they diffuse carbon dioxide into their leaves through tiny holes called stomata. No, at night plants do not photosynthesize (because they need light to do so) so they have no need for carbon dioxide. Instead, as they still need to respire, they produce carbon dioxide as a waste product from respiration.
