Question

Differentiate between Cork cambium and vascular cambium

Answer 1

Hint:The secondary growth of the plants is liable for the cork cambium and vascular cambium. Consequently, they are only present in dicotyledonous species.

Complete answer:
First we should know about cork cambium and vascular cambium to answer this question. Two lateral meristems (undifferentiated cells) that are responsible for the secondary development of plants are cork cambium and vascular cambium. Cork cambium is formed by dedifferentiated Parenchyma Cells. It lies in the cortex's outer portion. It develops cork cells and replaces the epidermis with cork cells. The vascular cambium is a cylinder of cells with a thickness of one cell layer. In order to expand existing rays or to create new rays, it adds secondary xylem to the interior and to the exterior and parenchyma cells the secondary phloem is added. It is found outside the pith and primary xylem in the woody stems and within the cortex and primary phloem. It is found outside the primary xylem in the woody roots and within the primary phloem.

Cork cambium	Vascular cambium
Cork cambium is secondary origin	Vascular cambium has both secondary and primary origin.
Cork cambium is found in the outer region of the cortex.	Vascular cambium is found between primary xylem and primary phloem
Cork cambium generates cells on its exterior.	Vascular cambium generates secondary phloem on its exterior.
Phelloderm is formed by Cork cambium in its interior.	Vascular cambium develops secondary xylem in its interior.
Cork cambium generates lenticels that facilitate the exchange of gas between wood and outside air.	Vascular rays generated by vascular cambium enable the transformation of water and nutrients between secondary xylem and secondary phloem.

Note:Both vascular cambium and cork cambium can be regarded as meristematic tissue that produces new cells in the secondary plant body that increase protection, girth, and allow efficient movements of gas, nutrients and water.
