Some of these terms/chemicals are associated with the `C_(4)` cycle. Explain.
(a) Hatch Slack pathway
(b) Calvin cycle
( c) PEP carboxylase ltbegt (d) Bundle shelth cells

Explanation

The terms associated with `C_(4)` cycle are
Hatch Slack Pathway The process of synthesis of glucose in `C_(4)` plants is different from `C_(3)` plants which was discovered by two scientist MD Hatch and CR Slack (1977). Hence, named Hatch Slack pathway.
PEP Carboxylase It is an enzyme present in mesophyll cell of `C_(4)` plants. It fixes `CO_(2)` to form 4-carbon compound, i.e.,oxaloacetate (OAA).
Bundle Sheath Cells These are specialised sclerenchymatous cells present arround the vascular bundle, in the veins of monocoat leaves. These have agranal chloroplast . `C_(3)` cycle occurs in these cells to manufacture glucose in `C_(4)` plants.
