Describe the Internal Structure of Monocot Root

The internal structure of a typical dicot root shows following features. Many epidermal cells prolong to form long hairy bodies the typical unicellular hairs of roots.

It is single-layered and composed of thin- walled cells.

. It contains more cuticle than dicot roots. Primary Structure of Monocot Root Anatomy Monocot roots shows following distinct regions. The difference between dicot and monocot root is dicot root contains xylem in the middle and phloem surrounding it.

In dicot roots the vascular structures are located in the middle of the root surrounded by vascular cambium. Number of Vascular Tissues. They are epiblema or rhizodermis cortex and stele.

I Unicellular root hairs are present in the epiblema in which cuticle is absent. Internal Structure of Orchid Root. The outermost layer of parenchymatous cells without intercellular spaces.

ABOUT DIAGRAMThe internal structure of a monocot root like maize rice wheat etc. Epiblema is the outermost single layer made from compactly arranged parenchymatous cells without intercellular space. Epidermis of root is also called epiblema or piliferous layer pilus hair.

The radial and the inner tangential walls of endodermal cells are thickened with suberin. Dicot root is narrow and has a tap root-like structure. Region of root tip where cells get longer thus lengthening the root.

Outermost layer of the roots system which is single layer and thin layered. 1 Number of xylem bundles are more than six Polyarch in monocotyledon root exceptionally the number of xylem bundles are two to six in onion. Anatomy of primary monocot root.

It comprises of 2-3 layers of thick-walled. Pith Features of Different Regions of Monocot Root 1. A root system that is composed of one main primary root and many secondary roots branching off the primary root is called a taproot system.

Tulips onions lilies and garlic are examples of monocot stems. Epidermis is the outermost layer of the stem and it is sole layered and lack of chloroplast. It is the single outermost layer composed of small thin-walled somewhat barrel-shaped parenchymatous cells.

Root hairs increase the absorbing surface of the root. Monocot and Dicot differ from each other in four structures. Monocot roots have a larger number of vascular structures than dicot roots.

ABOUT VIDEOThe internal structure of a dicot root can be studied from transverse section of a young root of sunflower gram and pea. Root hairs are always single celled. The internal structure of the monocot roots shows the following tissue systems from the periphery to the centre.

While monocot root contains xylem and phloem in another manner forming a circle. The arrangement of tiss. Can be described as follows1.

Dicot root has fewer numbers of xylem and phloem ie 2 to 8. These cells are much tightly packed and small root hair having single cell hairs comes out of this layer. 2 Pith is well developed in monocotyledon root.

The outer walls of epidermal cells are not cutinised. Internal structure of monocot root The epidermis on the outside of the root consists of a single layer of cells. Internal Structure of Monocotyledon Root.

Outward extensions of epicermal cells which extend between soil particles to collect water and solutes minerals. A type of taproot highly specialized for the storage of starches is called a napiform root. It consists of a single row of thin-walled parenchymatous cells without any intercellular space.

Some of the epidermal cells have root hairs. Root hairs are always single celled. These plant roots have a comparatively wider and fibrous root-like structure.

Many dicot plants have taproot systems. Identifying characteristics of the internal structure of monocot root. Examples of napiform roots include radishes beets turnips and carrots.

Also read Anatomy of Monocot and Dicot Plants. Normally dicots and monocots differ in four aspects which include stems flowers leaves and roots. Cells of this layer are colourless polygonal in shape and are without intercellular spaces.

In monocot roots xylem and phloem tissue bundles are arranged in a circular fashion around the central pith which consists of ground tissue parenchyma. Leaves stems roots and flowers. These cells may store food reserves.

Monocot root has a large number of xylem and phloem ie 8 to many. It lies just below the epidermis. Epiblema is single covered thin-walled colorless polygonal without intercellular spaces with the existence of unicellular root hairs.

Internal Structure of Dicot root. It is made up of single layer of barrel shaped parenchymatous cells. The epidermis or outermost lay.

These plant roots have a comparatively narrow and tap root-like structure. Cortex consists of oval or rounded loosely arranged parenchymatous cells. Root system of the monocots is as follows.

The internal structure of a typical monocotyledon root is similar to dicotyledon root. The internal structure of a monocot stem mainly comprises a well-developed epidermis hypodermis ground tissue and numerous dispersed vascular bundles. It plays a significant role in protection.

It is the outermost layer of the root. Monocot root is comparatively wider and has fibrous root-like structure. The cortex forms the layer below the epidermis and is made up of thin-walled parenchyma cells.

Older section of root tip where the root begins adding cells to increase the width and where root hairs form. It is mainly composed of hard organised rectangular cells coated with a waxy substance known as cutin. Anatomical structure of Monocot Stem.

Stomata and cuticle are absent. Both Monocot and Dicot roots belong to plants. It lies below the epidermis.
