Anatomy of Dicot Root (Primary Structure)
(Primary Anatomical Structure of a Dicot Root- Tinospora / Ficus Cross Section under Microscope)

Ø  Anatomy of a dicot root primary structure can be studied through a Cross Section (CS).

Ø  Anatomically, the primary structure in a dicot root is differentiated into the following tissue zones:

(1).   Root cap

(2).   Epidermis

(3).   Cortex

(4).   Endodermis

(5).   Pericycle

(6).  Vascular Tissue

(7).   Conjunctive Tissue

(8).   Pith

Anatomy of Monocot Root Cross Section Key Points with PPT

Monocot Root Cross Section

Anatomy of Monocot Root
(Monocot Root Cross Section Under Microscope with Diagram)

Ø  The anatomical features of a monocot root can be studied through a cross section (CS) through the root.

Ø  Anatomically, the monocot root has been differentiated into the following parts:

(1).    Epidermis

(2).    Cortex

(3).    Endodermis

(4).    Pericycle

(5).    Vascular Tissue

(6).    Conjunctive Tissue

(7).     Pith

(1). Epidermis

Ø  Epidermis in the root is also known as epiblema, piliferous layer and rhizodermis.

Ø  It is the outermost layer in the root, composed of closely packed parenchymatous cells.

Ø  Usually, the epidermis is single layered with thin walled cells.
