Difference Between Monocot and Dicot Stem

Plants are classified in many ways, and one of the most common methods is flowering plants vs. flowering plants. non-flowering plants. Most of the green plants we see around are flowering plants. Historically, flowering plants have been divided into two classes that include monocots (monocots) and dicots.

Difference Between Monocot and Dicot Stem

Monocots or monocots generally refer to flowering plants or angiosperms with seeds that usually have only one embryonic leaf or cotyledon Peppers, onions, wheat and grasses are good examples of monocots.

Dicots or leaves are often referred to as flowering plants or angiosperms, the seeds of which usually have two embryonic leaves or leaves. Beans, peas, peas, and peas are all examples of dicots. There are about 1.0 – 1.5 million dioecious species.

What is Monocot Stem?

Monocot stems are a rectangular stem with lateral branches, bordered by a membrane layer. It is basically composed of hard, organized, rectangular cells covered with a wax-like substance known as cutin.

The internal structure of a monocot consists mainly of a well-developed epidermis, epidermis, folds, and many scattered vascular bundles. Tulips, onions, lilies, and garlic are examples of a monocot.

What is Dicot Stem?

Dicot stems have a well-defined cuticle, a layer of multicellular root hairs. The internal structures of a diploid root are mainly epidermis, subcutaneous tissue, cortical endoderm, pericycle, vascular cords, and pith. Sunflower and zucchini are examples of two leaves.

Usually two leaves and one species are divided into four elements, namely stem, flower, leaf and stem. Read on to learn how monocot and bivalve leaves differ from each other.

Difference Between Monocot and Dicot Stem

Dicot

Monocot

The dicot stem is solid in most of the cases. The monocot stem is usually hollow at the centre.
The hypodermis is formed of collenchyma fibres which are often green in colour. The hypodermis is made of sclerenchyma fibres and they are not green.
The internal tissues are arranged in concentric layers. There is no concentric arrangement of tissues.
The ground tissue is differentiated as endodermis, cortex, pericycle, medullary rays, pith, etc. The ground tissue is the same and is composed of a mass of similar cells.
The vascular bundles are formed as broken rings. The vascular bundles are scattered irregularly around the ground tissue.
Phloem parenchyma is present. Phloem parenchyma is absent.
Pith is well-developed. Pith is not as well-developed in monocots (usually absent in most)
Epidermal hair may or may not exist. Presence of epidermal hair.
Vascular bundles are less in number and are of uniform size. There are numerous vascular bundles of different sizes.
The dicot stem does not have a bundle sheath on the outside of a vascular bundle. The monocot stem has a sclerenchymatous bundle sheath on the outside of a vascular bundle.
The dicot stems have trichomes. The monocot stems do not have trichomes.
The vascular bundles always remain open, due to the presence of cambium within phloem and xylem. The 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 in a 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.
