Question

Hi....can you explain about cork cambium

Answer 1

=>the meristematic tissue which develops in the cortex region called as cork cambium or phellogen .
=>the phellogen cut off cells on both sides
the outer cell differentiation to form cork or phellem while the inner is differentiated to the
secondary cortex or phelloderm
=> phellogen, phelloderm,phellem is collectively called as periderm

Answer 2

★ CORK CAMBIUM:-

→ The outer cortical and epidermis layers get broken and need to be replaced to provide new protective cell layers.

→ Hence another meristematic tissue called cork cambium develops, usually in the cortex region.

→ Phellogen is a couple of layers thick.

→ Phellogen cuts off cells on both sides. The outer cells differentiate into cork while the inner cells differentiate intosecondary cortex.

→ Cells of secondary cortex are parenchymatous.

→ The cork is impervious to water due to suberin deposition in the cell wall.

→ Phellogen, phellem, and phelloderm are collectively known as periderm.

→ The pressure builds up on the remaining layers peripheral to phellogen and ultimately these layers die and slough off.
