Vedclass · Answer

(D) During the day,when stomata are open for photosynthesis,$CO_2$ diffuses into the leaf while water vapour diffuses out due to transpiration.These two processes occur simultaneously because the diffusion of gases is independent of each other.According to Fick's law of diffusion,the rate of diffusion depends on the concentration gradient and the diffusion coefficient of the specific gas.Since the diffusion coefficients of water vapour and $CO_2$ are different,they can move in opposite directions through the same stomatal pore at the same time without interfering with each other.

List-$I$	List-$II$
$(1)$ Heavy water	$(a)$ Bicarbonates of $Ca$ and $Mg$ in water
$(2)$ Temporary hard water	$(b)$ No foreign ions in water
$(3)$ Soft water	$(c)$ $D_2O$
$(4)$ Permanent hard water	$(d)$ Sulphates and chlorides of $Ca$ and $Mg$ in water

Water vapour comes out from the plant leaf through the stomatal opening. Through the same stomatal opening,carbon dioxide diffuses into the plant during photosynthesis. Reason out the above statements using one of the following options:
