In the case of the $C_4$ pathway:

Compared to $C_3$ plants,how many additional $ATP$ molecules are required to produce one molecule of hexose in $C_4$ plants?

For the observation of $Kranz$ anatomy,which plant is useful?

Observe the diagram and answer the following:
$(a)$ Which group of plants exhibit these two types of cells?
$(b)$ What is the first product of the $C_4$ cycle?
$(c)$ Which enzymes are present in bundle sheath cells and mesophyll cells?

The enzyme which catalyzes the primary carboxylation step in the photosynthetic $C_4$ cycle is:

The net requirement of assimilatory power for the formation of $6$ hexose molecules in a maize plant is:
