DENDROLOGY

Detailed explanation-1: -Primary roots are the early roots in young plants that consist of taproots, basal roots, and lateral roots. Secondary roots are the side branches of the primary roots.

Detailed explanation-2: -Root tips ultimately develop into two main types of root systems: tap roots and fibrous roots. The growing root tip is protected by a root cap. Within the root tip, cells differentiate, actively divide, and increase in length, depending on in which zone the cells are located.

Detailed explanation-3: -taproot, main root of a primary root system, growing vertically downward. Most dicotyledonous plants (see cotyledon), such as dandelions, produce taproots, and some, such as the edible roots of carrots and beets, are specialized for food storage.

Detailed explanation-4: -(A) A typical taproot system of dicots (e.g. Arabidopsis thaliana), consisting of embryonic primary root (PR, red) and branching lateral roots (LRs, brown). Ultimately, the LRs will undergo higher order branching to form secondary and tertiary LRs.

Detailed explanation-5: -1.1 The tap root or primary system. Dicotyledonous plants possess a primary root called the tap root with lateral secondary roots branching out from it and sometimes additional tertiary roots branching from the secondary roots.
