In $C_{4}$-plants,the RuBisCO enzyme is present in:

Which enzyme catalyzes the photosynthetic $C_4$ cycle?

Which of the following anatomical features characterize a $C_4$ plant?

Who proposed the $CAM$ pathway of $CO_2$ fixation?

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.

$A-$ 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.
