Dicot Root vs. Monocot Root

Both, Monocot and Dicot roots belong to plants. Monocots and Dicots differ from each other in four structures: leavesstems, roots and flowers. The difference between dicot and monocot root is, dicot root contains xylem in the middle and phloem surrounding it. While, monocot root contain xylem and phloem in another manner, forming a circle. The monocot roots are fibrous while that of dicot are tap roots.

As we all know that plants are mainly divided into two kinds, Namely flowering plants and non-flowering plants (angiosperms or gymnosperms). It needs to be kept mentioned that approximately 80 per cent of all of the present green plants are flowering plants. That flowering plants are further divided into monocots and dicots.

The monocot is the plant which has just a single cotyledon in the embryo, whereas dicot is the plant that has two cotyledons from the embryo. Monocots and dicots differ from one another in four structures: leaves, stems, flowers and roots. Here we will discuss difference between the roots of the monocot and dicot plant. In monocot roots, the pericycle present just produce the roots, whereas, in dicot roots, the pericycle gives rise to roots, cork cambium, and the component of the vascular cambium. The other major difference between the monocot roots and dicot roots is that the existence of xylem and phloem. In Monacot, the xylem and phloem are numerous in numbers. while, In dicot, the xylem and phloem are restricted in numbers.

What is Dicot Root?

Dicot root has xylem in the form of ‘X’ that Is surrounded by phloem. and, it has got tap roots. In a dicot root, the amount of xylem and phloem is continuous. Vessels of xylem are angular or polygonal shape, when we cut it in transverse section. Conjunctive tissue at a dicot root is parenchymatous, which creates vascular cambium.

What is Monocot Root?

Monocot Root has xylem and phloem within an alternating manner. What’s more, it has fibrous roots. Xylem and phloem are presents numerous in number in a monocot root. The vessels of xylem are rounded or oval shape. Conjunctive tissue at a monocot root is mostly sclerenchymatous, at times it could be parenchymatous also.

Key Differences between Dicot Root and Monocot Root

  1. In a dicot root, the number of xylem and phloem is continuous while in a monocot, they are numerous in number.
  2. Pith is absent or very small at a dicot root while it is Big and well developed at monocot root.
  3. Xylem vessels are curved in a monocot root and angular at a dicot root.
  4. The cortex of a Monocot root is broad while that of a dicot root is narrow.
  5. Secondary growth occurs in a dicot root but not in a monocot root.
