Cortex
Cork cambium is the layer of tissue that produces cork cells, which accumulate to form the protective cork layer. This cork layer functions to protect the stem or trunk of a plant from physical damage, pathogens, and water loss. Cork is a natural insulator and has properties that make it resistant to fire and decay, providing additional protection to the plant.
Cork cells form a protective layer around plant stems.
Cork.
cork layer
Natural cork is a layer harvested from the cork oak and so was once part of a living thing. Once harvested and formed for use, it is no longer alive. -------------------------------------------------------------------------------------------------------- Cork is a type of tree bark and forms a dead outer protective layer on the tree. Once harvested from the trees and made into corks for bottles, cork boards, etc. it is long dead.
Cork is an external, secondary tissue that is impermeable to water and gases, and is also called the phellem. The cork is produced by the Cork cambium which is a layer of meristematically active cells which serve as a lateral meristem for the periderm. The cork cambium, which is also called the phellogen, is normally only one cell layer thick and it divides periclinally to the outside producing cork. The phelloderm, which is not always present in all barks, is a layer of cells formed by and interior to the cork cambium. Together, the phellem (cork), phellogen (cork cambium) and phelloderm constitute the periderm. Cork cell walls contain suberin, a waxy substance which protects the stem against water loss, the invasion of insects into the stem, and prevents infections by bacteria and fungal spores.
subcutaneous layer. its the third layer of skin made up of adipose tissue (fat) which is made up of adipocytes. it lies benath the dermis which lies beneath the epidermis, your outermost layer of skin.

A cork is seal for a bottle. Traditionally, corks were made out of a type of aged wood. Nowadays, most corks are made out of plastic, though wooden corks are still used for higher end wines. The verb form of cork means to close or sealsomething. The idiom, put a cork in it, means to stop speaking.Cork is the buoyant, light brown substance obtained from the outer bark layer of the cork oak. It is used to seal bottles.
Cork is a plant cell; it is the bark of the "cork oak" a type of oak tree that grows in Spain and similar climates.
