Why do the `C_(4)` plants show better yield and high productivity than ` C_(3) ` plants ?

Text Solution

Verified by Experts

The `C_(4)` plants have evolved a mechanism to avoid photorespiration which may otherwise lead to 25 precent loss of `Co_(2)` fixes. These plants have a mechanism that increases the concentration of ` CO_(2)` at the RuBisCO site and thus minimising the oxygenase activity of the enzyme.
