Detailed explanation-1: -Cork cambium is the tissue seen in several vascular plants as a portion of the epidermis. Found between the cork and the primary phloem, it is one of the several layers of the bark. Cork cambium is the lateral meristem that is accountable for secondary growth substituting the epidermis in the roots and stems.
Detailed explanation-2: -The cork cambium, or phellogen, produces the protective outer layers of the bark.
Detailed explanation-3: -Occurrence of secondary growth due to the activity of two laterally positioned meristems, viz. the vascular cambium and the phellogen (cork cambium) is a common feature of the gymnosperms and dicotyledons.
Detailed explanation-4: -The vascular cambium and cork cambium are secondary meristems that are formed in stems and roots after the tissues of the primary plant body have differentiated. The vascular cambium is responsible for increasing the diameter of stems and roots and for forming woody tissue. The cork cambium produces some of the bark.
Detailed explanation-5: -Phellogen – also called cork cambium.
