WebNov 14, 2024 · The bundle sheath cells are surrounded by a layer of mesophyll cells that are compactly arranged to form a concentric ring-shaped structure. These are generally only two mesophyll cells between vascular bundles in C 4 leaves as opposed to up to 18 cells in C 3 leaves ( Sage et al., 2014 ). WebThe mesophyll cells lack R u B i s CO enzyme. The C 4 acid O AA is formed in the mesophyll cells. The C O 2 released in the bundle sheath cells enters the C 3 or the Calvin pathway, a pathway common to all plants. The bundle sheath cells are rich in an enzyme Ribulose bisphosphate carboxylase-oxygenase (R u B i s CO), but lack PEP Case.
