Numerous plants of the family ......... are of the $C_4$ type.

Assertion: $C_4$ pathway of $CO_2$ fixation is found in some tropical plants.
Reason: In this pathway,$CO_2$ is fixed by $3C$ compound.

$C_4$ plants are less efficient at low temperatures due to:

In the maize plant,$CO_2$ fixation occurs in both mesophyll and bundle sheath cells. The enzymes involved in these cells for the process respectively are

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?

$C_4$ plants can tolerate saline conditions due to
