Monocot and Dicot Stem

Plants are generally classified into two types namely angiosperms or gymnosperms scientifically or in simple terms they are divided as flowering plants and non-flowering plants. Most of the green plants that we see around belong to the flowering plants category. However, these flowering plants are also divided into two types which include monocots and dicots.

As such, we will be dealing with the topic of monocot and dicot in this page. We will try to understand what makes the two types unique and why is it important to understand the difference between a monocot and dicot plants.

Differences Between Monocot and Dicot Stem

Normally, dicots and monocots differ in four aspects which include stems, flowers, leaves, and roots. Here we’ll be looking at the differences between a monocot and dicot stem of a plant.

Differences Between Monocot and Dicot Stem

Dicot

Monocot

Dicot has two cotyledons.

Monocot has one cotyledon

Here the hypodermis is formed of collenchyma which is often green in color.

The hypodermis is made of sclerenchyma fibres and they are not green.

The arrangement of internal tissues are in concentric layers.

There is no concentric arrangement of tissues.

In dicot the ground tissue is differentiated as endodermis, cortex, pericycle, medullary rays, pith, etc.

The ground tissue is the same and is a mass of similar cells.

The stem is solid in most of the cases.

The stem is usually hollow at the center.

The vascular bundles of formed as broken rings.

The vascular bundles are scattered irregularly around the ground tissue.

Vascular bundles are less in number and are of uniform size.

Numerous vascular bundles of different sizes are found.

Dicot stem does not have a bundle sheath on the outside of a vascular bundle.

In monocots, a sclerenchymatous bundle sheath is found.

Due to the presence of cambium within phloem and xylem vascular bundles remain open.

In this case, vascular bundles are closed.

Dicot stem can feature secondary growth as a result of secondary vascular tissues and periderm formation.

No secondary growth is witnessed in case of monocots.

Vessels are of a polygonal shape and are arranged in rows or chains.

Vessels are rounded or oval and are arranged Y-shaped formation.

Usually vascular tissues stop functioning when they get old. New vascular tissues replace the old ones.

Vascular tissues remain the same throughout the plant’s life cycle.

These are some of the differences between monocot and dicot stem. To know more about plants and other biology topics you can keep visiting BYJU’s or download our app for interesting content and learning experience.
