Question

In a transverse section of cork, dead cells from outer side to inner side will be present as


Epidermis-Phellem-Phellogen-Secondary cortex



Phellem-Secondary cortex-Phellogen-Epidermis



Epidermis-Phellogen-Phellem-Secondary cortex



Phellem-Phellogen-Epidermis-Secondary cortex
which opton corrct

Answer 1

Answer:

option a is correct

Explanation:

As stem increase it's width,outer epidermis layers get broken and another meristematic tissue called cork cambium or phellogen developes.phellogen cuts off cells on both sides,outer into cork or phellem and inner into secondary cortex or phelloderm.

hence, the order from outside to inside will be

Epidermis,phellem,phellogen and secondary cortex.

hope it helps...!!thank you...!!

Answer 2

In a transverse section of cork, dead cells from outer side to inner side will be present as:

Epidermis-Phellem-Phellogen-Secondary cortex

• The epidermis is the outermost part in a transverse section of cork.

• When the stem of a tree increases in width, the epidermis starts degenerating to form a structure called cork cambium or phellogen.

• This phellogen further initiates the formation of phellem and phelloderm in the cork cambium.

• Cells growing towards the inner side are referred to as phelloderm whereas the cells growing towards the outer side are referred to as phellem or cork.
