Given below are two statements :Statement I: The primary CO2 acceptor in C4 plants is phosphoenolpyruvate and is found in the mesophyll cells.Statement II: Mesophyll cells of C4 plants lack RuBisCo enzyme. In the light of the above statements,

📌Concept: Plants that are adapted to dry tropical regions have the C4 pathway.  C4 plants have a special type of leaf anatomy, they tolerate higher temperatures, they show a response to high light intensities, they lack a process called photorespiration, and have greater productivity of biomass. 
✅Explanation:  Plants in tropical desert regions commonly follow the C4 pathway. Here, a 4-carbon compound called oxaloacetic acid (OAA) is the first product of carbon fixation. Such plants have certain adaptations as well.
Statement I:  The primary CO2 acceptor is a 3-carbon molecule, phosphoenol pyruvate (PEP), and is present in the mesophyll cells. The enzyme responsible for this fixation is PEP carboxylase or PEPcase. This statement is correct.
Statement II:  Mesophyll cells of C4 plants lack the RuBisCO enzyme.  The C4 acid OAA is formed in the mesophyll cells. This statement is correct.
