In sugarcane plants,$^{14}CO_2$ is fixed into malic acid. Which enzyme is responsible for the fixation of $CO_2$ in this process?

Which plant responds to higher temperature and shows a higher rate of photosynthesis?

The $C_{4}$ plants are twice as efficient as $C_{3}$ plants in terms of fixing $CO_{2}$ but lose only $........$ as much water as $C_{3}$ plants for the same amount of $CO_{2}$ fixed.

Suppose $Euphorbia$ and $Maize$ are grown in the tropical area. Which one of them is more efficient in terms of photosynthetic activity?

In the leaves of $C_4$ plants,malic acid formation during $CO_2$ fixation occurs in the cells of

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.
