Vedclass · Answer

(C) Let's analyze each statement:$(1)$ Incorrect: $C_4$ plants are adapted to high temperatures and show higher productivity at higher temperatures compared to $C_3$ plants.$(2)$ Correct: $C_4$ plants show a positive response to high light intensities and do not show saturation at lower light levels.$(3)$ Correct: $C_4$ plants lack photorespiration because they have a mechanism to increase the concentration of $CO_2$ at the enzyme site (Rubisco),which minimizes the oxygenase activity of Rubisco.$(4)$ Incorrect: $C_4$ plants have higher productivity than $C_3$ plants due to the absence of photorespiration and efficient $CO_2$ fixation.$(5)$ Correct: The primary $CO_2$ fixation occurs in the mesophyll cells where $PEP$ carboxylase fixes $CO_2$ into a $4$-carbon compound called Oxaloacetic acid $(OAA)$.Therefore,statements $(2), (3),$ and $(5)$ are correct.
