Explanation: 

Detailed explanation-1: -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-2: -The primary root, or radicle, is the first organ to appear when a seed germinates. It grows downward into the soil, anchoring the seedling. In gymnosperms and dicotyledons (angiosperms with two seed leaves), the radicle becomes a taproot.

Detailed explanation-3: -A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward.

Detailed explanation-4: -Taproots are commonly found in plants like beetroot, burdock, carrot, sugar beet, dandelion, parsley, parsnip, poppy mallow, radish, sagebrush, turnip, common milkweed, cannabis, and trees such as oaks, elms, pines, and firs are some of the taproot plant names.
