`C_(4)` pathway is advantageous over `C_(3)` pathway in plants as it

Options

A. occurs in relativity low `CO_2` concentration
B. uses more amount of water f
C. occurs in relativiely low `O_2` concentration
D. is less efficient in energy utilisation

Answer

A

Explanation

A plant with the `C_4` -pathway is advantageous over a plant wiht a `C_3` - pathway as `C_4`-pathway can occur in low `CO_2` concentration . When the weather is hot , acid and dry , the leaves close their stomata ot climinate less water.
In a `C_3`-plant this closure results in low carbon dioxide concentration and ultimately both loss of RuBP and intribution of the Calvin -Benson cycle occurs by photorespiration.
