Dicot Root vs. Monocot Root

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 3, 2023
Dicot roots typically have a xylem in star shape and cambium present, while monocot roots have a xylem and phloem in a ring shape and no cambium.

Key Differences
On the other side, monocot roots display a vascular bundle pattern where the xylem and phloem are organized in a circular manner. Monocot roots exhibit certain characteristic features which include a pith, and lack of secondary growth. This structural formation aids in a specialized nutrient transport mechanism which varies significantly from the dicot roots.

Dicot roots and monocot roots differentiate primarily through their vascular bundle arrangements and number of seed leaves or cotyledons. The dicot root generally demonstrates a specific anatomical pattern that distinguishes it from its monocot counterpart. In the case of dicot roots, the xylem and phloem are arranged in a star-like pattern, a feature that enables a distinct functionality in terms of nutrient and water transport.

Monocot roots, however, typically do not undergo secondary growth because they lack vascular cambium. Consequently, the absence of secondary growth in monocot roots implies that they don't thicken over time. This inherently affects the longevity and structural development of monocot plants, directing them towards a different evolutionary pathway in comparison to dicot plants.

Secondary growth, which is often associated with an increase in thickness, is commonly found in dicot roots due to the presence of a vascular cambium. This element of secondary growth is crucial for the support and longevity of dicot plants, ensuring that they can acquire and transport nutrients efficiently as they mature and grow.

It's also noteworthy that dicot roots usually initiate from the radicle (embryonic root), providing them a structural starting point that influences subsequent development. Whereas, monocot roots often tend to exhibit more adventitious roots, meaning they can sprout from stems and leaves, displaying a diverse array of origination points which in turn influences their overall growth pattern and structural support system.

Monocot Root
Generally, monocot roots lack a vascular cambium, preventing secondary growth and thickening of the roots.

Dicot Root
Dicot roots frequently originate from the radicle, developing into a primary root system.
In beans, the dicot root develops directly from the radicle, providing support and nutrient transport.

Monocot Root
Monocot roots typically do not undergo secondary growth and thus do not become woody or thick.
The garlic plant, having a monocot root, does not develop a thick, woody root structure.
