Mr Ten Departure Betwixt The Secondary Increase Inwards Dicot Stalk In Addition To Dicot Root

The increase inward thickness past times the action of secondary tissues is called secondary thickening. It involves stelar increase past times the action of vascular cambial band in addition to extra stelar increase past times the activity  of cork cambium.
Dicot stem

1. The cambial band formed is circular inward cross department from the foremost onwards.
2. The cambial band is partially main (fascicular cambium) in addition to partially secondary (interfascicular cambium).
3. Periderm orginates from the cortical cells (extra stelar inward origin).
4. In Dicot stem, for mechanical back upwards xylem is alongside comparatively smaller vessels, greater fibers in addition to less parenchyma.
5. More total of cork is produced for protection.
6. Lenticels on periderm are real prominent.

Dicot root

1. The cambial band formed is wavy inward the foremost in addition to after becomes circular.
2. The cambial band is completely secondary inward origin.
3. Periderm originates from the pericycle (intra stelar inward origin).
4. In Dicot root, xylem is alongside big sparse walled vessels alongside few fibers in addition to to a greater extent than parenchyma.
5. Less total of cork is produced every bit root is underground.
6. Lenticels on periderm are non real prominent.
