Q. With regard to $C_3$ and $C_4$ plants, consider the following statements:
(1) $C_4$ plants are twice as efficient as $C_3$ plants in terms of fixing carbon.
(2) $C_4$ plants lose double the amount of water than a $C_3$ plant for the same amount of $CO_2$ fixed.
Which of the statement(s) given above is/are correct?

Transport in Plants

Solution:

The evolution of the $C _4$ photosynthetic system is probably one of the strategies for maximising the availability of $CO _2$ while minimising water loss.
$C_ 4$ plants are twice as efficient as $C_ 3$ plants in terms of fixing carbon.
$C_ 4$ plant loses only half as much water as a $C_ 3$ plant for the same amount of $CO _2$ fixed.
