These steps need not take place one after the other immediately. For example, desert plants take up carbon dioxide at night and prepare an intermediate which is acted upon by the energy absorbed by the chlorophyll during the day.

(ii) When do the desert plants take up carbon dioxide and perform photosynthesis ?

Stomata remain closed in desert plants during day time. How dothey perform photosynthesis?

In the carbon cycle, CO2 is taken in by plants through the process of what .

Recall the processes in corn plants that require the transfer of carbon dioxide to or from the atmosphere. PhotosynthesisTranspirationRespirationPollinationI'm not sure

Plants continually respire but photosynthesis requires sunlight. Explain how this produces a day-night cycle in the concentration of atmospheric CO2, seen in the video as a rapid pulsing.
