In sorghum grass,the first $CO_2$ acceptor is .....,the first product is .......,and the productivity is ...... .

Choose the correct statements regarding $C_4$ plants:
$(1)$ $C_4$ plants do not tolerate higher temperatures.
$(2)$ $C_4$ plants show a response to high light intensities.
$(3)$ $C_4$ plants lack a process called photorespiration.
$(4)$ Productivity of $C_4$ plants is less than $C_3$ plants.
$(5)$ $C_4$ acid $OAA$ is formed in the mesophyll cells.

As compared to a $C_{3}$-plant,how many additional molecules of $ATP$ are needed for the net production of one molecule of hexose sugar by $C_{4}$-plants?

$C_{4}$ pathway is advantageous over $C_{3}$ pathway in plants because it

$A-$ In $C_4$ plants,carboxylation takes place in the chloroplasts of mesophyll cells and bundle sheath cells.
$R -$ In $C_3$ plants,$CO_2$ fixation occurs in mesophyll cells and bundle sheath cells.
