(C) The periderm is a collective term for the secondary protective tissues formed in the stem and root of woody plants. It consists of three layers: the phellogen (cork cambium),the phellem (cork),and the phelloderm (secondary cortex). The phellogen is a meristematic tissue that gives rise to the periderm by producing phellem towards the outside and phelloderm towards the inside. Therefore,the periderm originates from the phellogen.
