Some of these terms/chemicals are associated with the C4 cycle. Explain.

1.  Hatch Slack pathway

2.  Calvin cycle

3.  PEP carboxylase

4.  Bundle sheath cells

 

 
The terms associatedwith C4 cycle are

Hatch Slack Pathway The process of synthesis of glucose in C4 plants is different from C3 plants which was discovered by two scientists MD Hatch and CR Slack (1977). Hence, named Hatch Slack pathway.
 
PEP Carboxylase It is an enzyme present in mesophyll cells of C4 plants. It fixes CO2 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 monocot leaves. These have agranal chloroplast. C3 cycle occurs in these cells to manufacture glucosein C4 plants.
 
Calvin Cycle This cycle operates in bundle sheath cells and fixes CO2 to form glucose molecules.
