Write a short note on kranz anatomy.

1.	Write a short note on kranz anatomy.
Answer» The word\xa0Kranz\xa0means “wreath” or “ring”.\xa0Kranz anatomy\xa0is a specialized structure in C4\xa0Plants 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.\xa0The particularly large cells around the vascular bundles of the C4\xa0pathway plants are called bundle sheath cells, and the leaves which have such\xa0anatomy\xa0are said to have \'Kranz\'\xa0anatomy.\xa0Kranz\' means \'wreath\' and is a reflection of the arrangement of cells.\xa0It has been thought that a specialized leaf\xa0anatomy, composed of two, distinctive photosynthetic cell types (Kranz anatomy), is required for C4 photosynthesis. We provide evidence that C4 photosynthesis can function within a single photosynthetic cell in terrestrial plants.
