$A$ plant in your garden avoids photorespiration,has improved water-use efficiency,shows a high rate of photosynthesis at high temperatures,and has improved nitrogen-use efficiency. To which physiological group would you classify this plant?

How many additional $ATP$ molecules are required in the $C_4$ pathway compared to the $C_3$ pathway for the fixation of one molecule of $CO_2$?

The correlation between 'Kranz' anatomy and the $C_4$ pathway of $CO_2$ assimilation was first established by:

The $C_4$ plants are photosynthetically more efficient than $C_3$ plants because

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.

Describe the internal anatomy of $C_{4}$ plants.
