Tap Root vs. Fibrous Root: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 14, 2023
A tap root is a primary, dominant root from which smaller lateral roots emerge, while fibrous roots are a network of similarly sized roots without a dominant root.

Key Differences

A tap root is the main, primary root that emerges directly from the seedling and grows downward into the soil, becoming thicker over time. In contrast, a fibrous root system consists of numerous roots that are roughly the same diameter, forming a dense and fibrous mat just beneath the soil surface.

The tap root system is typically seen in dicotyledonous plants. It allows plants to access water and nutrients from deeper layers of the soil. On the other hand, fibrous roots are common in monocotyledonous plants and are more adapted to gather nutrients and moisture from the top layers of the soil.

The tap root system provides strong anchorage due to its deep penetration, helping plants withstand strong winds and erosion. In contrast, plants with fibrous roots spread out widely but not deeply, offering support across a broader area but not accessing deeper soil layers.

Many plants with a tap root system, like carrots and radishes, store nutrients in their primary root. On the other side, plants with fibrous roots, such as grasses, do not typically store large amounts of nutrients in their roots but rather spread out to efficiently gather nutrients from the surrounding soil.

As plants mature, modifications can occur in root systems. A tap root might develop secondary roots that further aid in nutrient absorption. In some plants, the initial fibrous root system can evolve, with one root becoming more dominant, though it may not fully transform into a traditional tap root system.
