The differences between dicot root and monocot root can only be understood when you have clear information about angiosperms plants.
These flowering plants are divided into monocots and dicots. Both the plants differ in leaves arrangement, stems, and roots.
However, the guide provides detailed insight into the core distinction between monocot and dicot root. Let’s find out:
What Is Dicot Root?
Dicot root is a root structure common in dicot plants. The root tends to have a tap root-like structure that has a continuous amount of xylem and phloem tissues.
Xylem tissue is normally at the center of the root and surrounded by phloem tissues. Besides that, xylem has an angular shape.
Dicot roots tend to show secondary thickening and they are connected together by parenchyma tissue in the form of the vascular cambium.
Tap root-like structure is common in dicot plants like peas, mangos, oranges, and peanuts among many others.
What Is Monocot Root?
Monocot root has a fibrous root-like structure which is something common in monocot plants. The fibrous root-like structure tends to lie shallow on the ground surface making the plant easier to uproot.
Xylem and phloem tissue occur in ring-shape orientation. Xylem vessels are the oval shape and connected together by sclerenchyma tissues.
Monocot root does not show secondary growth due to a lack of cambium. Some of the common plants with monocot roots are maize, palm, and bananas.
Comparison Chart: Dicot Root Vs Monocot Root
|Basic Terms||Dicot Root||Monocot Root|
|Root Structure||Tap root-like structure||Fibrous root-like structures|
|Vascular Tissue Numbers||Have few numbers of xylem and phloem vessels||Have a lot of xylem and phloem vessels|
|Definition||The plant has two cotyledons||The plant has single cotyledons|
|Arrangement of Vascular Tissues||Xylem vessel is at the center and surrounded by phloem vessels||Both xylem and phloem vessels have a ring-like arrangement|
|The shape of the Xylem Vessel||Has an angular shape||Has oval shape|
|Cambium||Has cambium for secondary growth||Lack cambium hence no secondary growth|
|Size of Cortex||Quite Narrower||Quite large|
|Connective Tissues||Has parenchyma tissues||Has sclerenchyma tissues|
|Pith||Do not have pith||Has large and wide pith|
|Pericycle||Result in lateral roots and cambium formation||Forms lateral roots only|
|Xylem Vessels||Are tetrarch||Are polyarch|
|Examples||Peas, mangos, oranges, beans||Maize, bananas, palms|
Core Differences between Dicot Root and Monocot Root In Point Form
- Dicot root has planted with two cotyledons while monocot root has planted with a single cotyledon.
- Dicot root has a tap root-like structure and they are narrower while monocot root has a fibrous root-like structure which is comparatively larger.
- Monocot root has large and several xylem and phloem vessels while dicot root has a fewer number of both xylem and phloem vessels.
- Xylem is at the center and surrounded by phloem vessel in dicot root while in monocot root both xylem and phloem are in ring-shape.
- Pericycle in dicot root forms cork cambium lateral roots and vascular cambium while pericycle in monocot root only from lateral roots.
- The pith in dicot root is both very small and underdeveloped or not at all while in monocot root the pitch wide and large in size.
- Dicot roots are loaded with parenchyma connective tissues while the monocot root with sclerenchyma connective tissues.
- Cambium is present in dicot root while in monocot root cambium is absent.
- The size of the cortex in dicot root is quite narrower while that of monocot root is wide and large
- Dicot root typically experiences secondary growth due to vascular cambium while monocot root does not experience secondary growth.
- The older roots of dicot root are enclosed by cork while in monocot root they are covered with exodermis.
- Dicot root examples of plants are beans, peanuts, and mangos while monocot root plants are maize, palm, and bananas.
Similarities between Monocot and Dicot Roots
- Both have vascular bundles
- Both are used for anchorage
- Both occur in plants
- Both play a vital role in food, mineral and water transportation
Frequently Asked Questions
- How Are Monocot and Dicot Roots Different?
Monocots have fibrous roots webbed in many directions while dicot has a taproot system that digs deeper into the soil and has other smaller branches.
- Is Rice a Monocot or Dicot?
Rice is a grain that belongs to a monocot plant. Therefore, rice has fibrous roots just like millet, wheat, sugar cane, and corn among many other monocotyledonous plants.
- How Do You Identify a Dicot Root?
Dicot roots have cortex that is homogenous Endodermis consists of barrel-shaped compact parenchymatous cells. It contains both Casparian stripes and passage cells.
- What is the Difference between Dicot Stem and Dicot Root?
Dicot root has epidermis that contains root hairs whereas dicot stem has epidermis that contains trichomes, cuticle, and stomata.

It is always a good idea to know the plant based on the roots only and this will enable you to understand the full anatomy of the plant in the long run.
