Question : Mention important matters for C_(4) plants.

Answer»

Solution :In `C_(4)` plants photorespiraiton does not occur. This is because they have a MECHANISM that increase the concentration of `CO_(2)` at the ENZYME SITE.
This takes place when the `C_(4)` acid from themesophyll is BROKEN down in the bundle cells to release `CO_(2)`.
This RESULTS in increasing the intracellular concentration of `CO_(2)`.
In turn, this ensures that the RuBisCO functions as a carboxylase minimising the oxygease activity.
So the productivity of `C_(4)` is more
