DENDROLOGY

Detailed explanation-1: -Dicots, one of the two divisions of flowering plants (angiosperms), start with a taproot, which is one main root forming from the enlarging radicle of the seed. The tap root can be persistent throughout the life of the plant but is most often replaced later in the plant’s development by a fibrous root system.

Detailed explanation-2: -So, the correct answer is ‘Radicle axis of the seed’.

Detailed explanation-3: -A taproot refers to the presence of a large single root growing downward from the base of the plant. Taproots often have smaller hair-like roots that emerge from the central root. Some examples of plants with taproots include dandelions, carrots, parsnips, and beets.

Detailed explanation-4: -Root vegetables, including jicama, parsnips, salsify, and turnips, are considered taproots. Several weeds such as plantain and kudzu survive with the help of taproots.
