If concentration of co2 (formed from malic acid)increases how does it effect the rate of transpiration and stomatal opening

Dear student

Please refer the solution below for the said query

The CO₂ acts as anti-transpirant. The increase in the concentration of CO₂ outside the leaves decreases the stomatal aperture and hence induces partial closure of the stomata. This in turn reduces transpiration.

The decrease in CO₂​ concentration favours opening of stomata. 



Hope this information clears your doubt about the topic.
