Detailed Solution

C₃ acids are not formed in mesophyll cells due to carboxylation but C₄ acids are formed.

C₃ acid Pyruvic acid is formed in bundle sheath cells due to decarboxylation.

C₃ acid 3-phosphoglyceric acid is formed in bundle sheath cells in the first reaction of Calvin cycle.

Mesophyll cells do not show decarboxylation of PEP during C₄ cycle reactions.
