Dicot Root vs. Monocot Root — What's the Difference?
By Tayyaba Rehman — Published on December 20, 2023
Dicot roots have two cotyledons, vascular bundles in a ring, and show secondary growth. Monocot roots have one cotyledon, scattered vascular bundles, and lack secondary growth.

Key Differences
Dicot roots are characteristic of plants that sprout two embryonic leaves or cotyledons during their initial growth. Monocot roots are found in plants that produce only one cotyledon. The structure of dicot roots is marked by the presence of vascular bundles, which are organized in a circular pattern. In contrast, monocot roots display these vascular bundles scattered throughout the root.
A significant feature of dicot roots is their ability to exhibit secondary growth, giving them the capability to become thicker over time. Monocot roots, on the other hand, don't typically show this secondary growth. This means that while dicot roots can expand in diameter, monocot roots maintain a relatively consistent width.
Lastly, when it comes to the type of plants these roots support, dicot roots are typically associated with a broader range of plant species, while monocot roots are limited to plants like grasses, lilies, and orchids.
