Select the incorrect statement as far as kranz anatomy is concerned.a)...
Kranz anatomy is a characteristic of C4 plants. In kranz anatomy, the mesophyll is undifferentiated and its cells occur in concentric layers around vascular bundles. Vascular which are surrounded by large-sized bundle sheath cells which are arranged in a wreath like a manner in one to several layers. The chloroplasts of mesophyll cells are smaller, they have well-developed grana and a peripheral reticulum but no starch. Mesophyll cells possess enzyme PEP case for initial fixation of CO2. The chloroplasts of the bundle sheath cells are agranal. They possess a peripheral reticulum and starch grains. Bundle sheath cells possess enzyme RuBisCO.

Incorrect Statement: Chloroplasts of bundle sheath cells possess well-developed grana lamellae.
Explanation:
Kranz Anatomy:
Kranz anatomy refers to the specialized anatomical arrangement of cells in certain plants, particularly in C4 plants. It involves the presence of two types of photosynthetic cells: mesophyll cells and bundle sheath cells. This anatomical arrangement helps in the efficient functioning of C4 photosynthesis.
Bundle Sheath Cells:
Bundle sheath cells are specialized cells that surround the vascular bundles in leaves. They play a crucial role in C4 photosynthesis by providing a protective and controlled environment for the Calvin cycle, which occurs in these cells. Bundle sheath cells are characterized by several features:
1. Large Size: Bundle sheath cells are larger in size compared to the surrounding mesophyll cells.
2. Arrangement: The bundle sheath cells are arranged in a wreath-like manner around the vascular bundles. They form one to several concentric layers.
3. Centrifugal Chloroplasts: Bundle sheath cells contain chloroplasts, which are generally located towards the periphery of the cell. These chloroplasts are called centrifugal chloroplasts.
4. Undifferentiated Mesophyll: The mesophyll cells surrounding the bundle sheath cells are undifferentiated and occur in concentric layers around the vascular bundles. This arrangement helps in the efficient transport of metabolites between mesophyll cells and bundle sheath cells.
5. Grana Lamellae: Bundle sheath chloroplasts possess reduced grana lamellae or may even lack them completely. Grana lamellae are the stacked membrane structures within chloroplasts that contain chlorophyll and other pigments involved in the light-dependent reactions of photosynthesis. Therefore, the statement that chloroplasts of bundle sheath cells possess well-developed grana lamellae is incorrect.
To summarize, the incorrect statement regarding kranz anatomy is that chloroplasts of bundle sheath cells possess well-developed grana lamellae. In reality, bundle sheath chloroplasts have reduced or absent grana lamellae. This adaptation allows for the efficient separation of the initial carbon fixation process (C4 pathway) in mesophyll cells from the Calvin cycle (C3 pathway) in bundle sheath cells.
