Question

Innermost layer of cortex is

• A. Endodermis
• B. Epidermis
• C. Exodermis
• D. Hypodermis

Answer 1

The correct option is A Endodermis

• Epidermis is the outermost covering of the primary plant body and is mostly represented by a single layer of compactly arranged, barrel-shaped parenchyma cells that delimit cotex on outer side.
• The inner most layer of cortex is the endodermis, which has compactly arranged barrel shaped cells.
• The outer suberized sub-epidermal layer of cortex is exodermis and it has unthickened passage cells and is mostly present in roots.
• Hypodermis refers to 5-7 layers of cortical cells present just beneath the epidermis. It is present in leaves not in roots.

So, the correct answer is option A.
