Difference Between Tap Root and Fibrous Root

In a plant, the root is a crucial structure, constantly providing the leaves and the stem with all the required water and mineral salts through the process of photosynthesis that occurs in them. However, different plants exhibit different root systems. The two main types of root systems observed are tap root system and fibrous root system.

What Is Tap Root System?

It is a primary root, tapering vertically downwards forming the centre through which subsidiary rootlets branch out. This mass of roots develops from the radicle of the embryo consisting of the taproot, secondary root, tertiary roots and rootlets.

The persistent primary root is the thickest, largest and prominent of all which narrows down towards the tip whereas the secondary and tertiary roots branch out in the first and second order.

What Is Fibrous Root System?

Unlike the tap root system, the fibrous or adventitious root system is the one in which all of the root branches are approximately of the same thickness as typically observed in grasses. It is made of several thread-like strands typically emerging from the stems and does not penetrate deep into the soil. This is because their roots secure firmly to the soil particles.

Difference Between Tap Root and Fibrous Root

The table below lists some of the important differences between Tap Root and Fibrous Root

Tap Root Fibrous Root
Primary root
Presence of a one large and long root One large, long root is absent
Level of penetration into soil
Deeply penetrates Does not penetrate deeply
Differentiation of the primary root
Taproot is the differentiated primary root, which later emerges as the centre of the root system Fibrous root is not the differentiated primary root and is eliminated in later stages
Develops from the stem?
No Yes
Lateral roots
Develop from main root Absent
Dicot plants Monocot plants
Presence in gymnosperms
Yes No
Presence in grass
No Yes
Role as a storage structure
Can store in some cases Does not store
Holding on to soil particles
Formation of a net not observed in order to hold soil particles Forms a network, thereby holding soil particles together at the surface

Frequently Asked Questions


What is a taproot?

Taproots have a main central primary root upon which, small, lateral roots called root hairs are attached. Mustard, carrot, beetroot, parsley, china rose and all dicotyledons are examples of taproot systems.


What is a fibrous root?

Fibrous roots are bushy roots in which thin, moderately branching roots grow from the stem. Rice, wheat, maize, marigold, banana and all monocotyledons are some examples of the fibrous root system.


What are the functions of the root?

Root plays a vital role in anchoring, absorption, storage and reproduction. Also, they check soil erosion, provide sustenance and also habitat to various organisms.
