What is functional significance of kranz anatomy? |
| Answer» The word\xa0Kranz\xa0means “wreath” or “ring”.\xa0Kranz anatomy\xa0is a specialized structure in C4\xa0plants where the mesophyll cells\xa0are\xa0clustered 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\xa0anatomy\xa0wherein there are large, bundle sheath cells around the vascular bundles of C4 pathway plants. The bundle sheath cells form several cells around the vascular bundles. They have a large number of chloroplasts. They have thick walls that are impervious to gaseous exchange.\xa0The primary\xa0function\xa0of\xa0Kranz anatomy\xa0is to provide a site in which CO2 can be concentrated around RuBisCO, thereby avoiding photorespiration. | |
