Do plants consume CO2 at night?

  • do plants consume CO2 at night?

  • Answer:

    Soya (Glycine max) dark respiration rates http://jxb.oxfordjournals.org/cgi/content/abstract/25/5/987 http://aob.oxfordjournals.org/cgi/content/abstract/mcm071v1 http://www.plantphysiol.org/cgi/content/abstract/79/3/684 Respiration rates of plants are sensitive to temperature changes. Plants take in carbon dioxide during photosynthesis in the day, and release it during respiration at night. But they don't necessarily photosynthesize and respire at the same rates. Eventually half of the CO2 they use in photosynthesis is released back to the atmosphere by plant respiration As long as there is no water, CO2 or nitrogen limits warmer summer temperatures will require more dark respiration to deal with the photosynthates produced during the long summer days. Several factors affect dark respiration. Light intensity & duration, water, nutrients, [CO2], and temperature all work together. Once the temperature goes over 30C dark respiration increases sharply releasing a maximal [CO2].

As photosynthesis requires light, this process can only occur during the day. In this period, plants draw carbon dioxide from the water and release oxygen into the water. At night however, there is no photosynthesis and the reverse occurs - plants consume oxygen and release carbon dioxide.

Plants do not consume CO2 at night because photosyntesis dont take place at night. Plants consume Oxygen at night in process of respiration. At day time CO2 is consumed because rate of photosynthesis is higher than respiration.

Plants consume carbondioxide only during day time... during night, plants undergo dark reactions of photosynthesis and hence they utilise oxygen and release carbondioxide...

Some plants do. CAM plants (which are usually desert plants) open their stomata at night to engage in gas exchange. So the answer would be yes, some do.

Miri

yeah, depending on the plant's nature
