Detailed explanation-1: -The common bottle cork is the product of phellogen. Phellogen produces cork or phellem on the outer side. The cork is impervious to water due to suberin deposition in the cell wall. Hence used as a bottle cork.
Detailed explanation-2: -Phellogen is the source of a traditional cork in a bottle. Phellogen develops cork, or Phellem, on the outer side. It consists of rectangular cells, dead and compactly organised, which have walls of suberized cells.
Detailed explanation-3: -Phellogen layer or cork cambium is a dividing zone of cells that forms phellem to the outside and phelloderm to the inside. In other words, it forms the outer bark. This cambial zone is constantly on the move outward as the tree grows.
Detailed explanation-4: -So the correct option is ‘Phellogen’.
