Kranz anatomy is found in the leaves of

In this article, we have discussed the kranz anatomy. We have also discussed the examples and the diagram of Kranz anatomy. The mainly large cells surrounding the vascular bundles of the C4 plants are termed bundle sheath cells and the leaves which have such structure are said to have Kranz anatomy.

Additional Information. In C3 pathway the primary product from sunlight is 3-phosphoglyceric acid to produce energy. In C4 pathway sunlight is converted into oxaloacetic acid which is later converted into energy. Last updated on Feb 13, Get Started. SSC Exams.

The C 4 pathway requires the presence of two types of cells i. The particularly large cells around the vascular bundles of C 4 plants are called bundle sheath cells, these cells may form several layers around the vascular bundles, they are characterised by having large number of chloroplasts, grana are absent, thick walls impervious to gaseous exchange and no extracellular spaces. This special anatomy of leaves of the C 4 plants is called Kranz anatomy. Similar Questions. Give comparison between the following : a C 3 and C 4 pathways, b Cyclic and noncyclic photophosphorylation.

Kranz anatomy is a specialized structure in C 4 Plants where the mesophyll cells are clustered around the bundle-sheath cells in a ring-like fashion. The number of chloroplasts in the bundle-sheath cells is more than that in the mesophyll cells. This is found in C 4 grasses such as maize and a few dicots. The Kranz anatomy is developed in three different steps:. Also read: Photosynthesis in Higher Plants. The light-dependent reactions and the Calvin cycle are separated in the C 4 plants. The Calvin cycle occurs in the bundle-sheath cells and the light-dependent reactions occur in the mesophyll cells. The atmospheric oxygen is fixed first to form 4-carbon compound oxaloacetate in the mesophyll cells, catalyzed by PEP carboxylase. Oxaloacetate is converted to malate which is transported to the bundle-sheath cells.

Marjorie R. Lundgren, Colin P. C 4 photosynthesis is a complex physiological adaptation that confers greater productivity than the ancestral C 3 photosynthetic type in environments where photorespiration is high. In most C 4 plants, the CO 2 -concentrating mechanism is achieved via the confinement of Rubisco to bundle-sheath cells, into which CO 2 is biochemically pumped from surrounding mesophyll cells. The C 4 biochemical pathway relies on a specific suite of leaf functional properties, often referred to as Kranz anatomy.
