Question

What is the difference between taproot and fibrous root? Explain the relationship between types of roots and leaf venation.

Answer 1

Answer:

Taproot is one of the two essential root systems where the primary root gives out branches of secondary and tertiary roots growing downwards as the primary root tapers towards the end.

The fibrous root is the other type of root system where the root develops from the stem in the form of thin and moderately branching roots without any primary root.

Explanation:

• Taproot has only one main long root. The smaller roots that grow from the main root are called lateral roots. Taproot grows vertically deep into the soil.
• Fibrous roots do not have a main root. All roots are similar. Fibrous roots are short and most of them grow horizontally in the soil.

If the leaf has parallel venation, the roots of the plant will be fibrous root and if the leaf has reticulate venation, the root is tap root. It is an interesting fact that the leaf venation and the type of roots in a plants are always related to each other.
