Detailed explanation-1: -This primary root is a taproot. In plants in which the taproot persists, smaller lateral roots (secondary roots) commonly arise from the taproot and may in turn produce even smaller lateral roots (tertiary roots). This serves to increase the surface area for water and mineral absorption.

Detailed explanation-2: -A taproot is a large, central, and dominant root from which other roots sprout laterally.

Detailed explanation-3: -Fibrous root systems have many small branching roots, called fibrous roots, but no large primary root. The huge number of threadlike roots increases the surface area for absorption of water and minerals, but fibrous roots anchor the plant less securely.

Detailed explanation-4: -The tap root system has one main root, which is short lived hence smaller roots called lateral roots/secondary roots emerge from it.

Detailed explanation-5: -A tap root system has a main root that grows down vertically, from which many smaller lateral roots arise. Dandelions are a common example; their tap roots usually break off when these weeds are pulled from the ground; they can regrow another shoot from the remaining root.
