Root and Shoot Studies 1

Plant belongs to kingdom Plantae is having a simple body consisting of the underground root system and the above ground shoot system (Fig 1).

The Root

·         Root is the underground part of the plant.
·         The main functions of the root system are absorption of water and minerals from the soil, providing a proper anchorage to the plant parts, storing reserve food material and synthesis of plant growth regulators like cytokines. Roots penetrate, bind, and stabilize the soil, helping to prevent soil erosion. Roots also stimulate the growth of soil micro- and macro-organisms, compact the soil, alter soil chemistry, through their secretions and add organic material upon their death.

  ·         In majority of the dicotyledonous plants, the direct elongation of the radicle leads to the formation of primary root which grows inside the soil. It bears lateral roots of several orders that are referred to as secondary roots, tertiary roots etc. The primary roots and its branches constitute the tap root system, as seen in fig 1.
·         In monocotyledonous , the primary root is short lived and replaced by a large number of roots. These roots originate from the base of the stem and constitute the fibrous root system, as seen in the wheat plant.
·         In some plants, like grass, Monstera and the banyan tree, roots arise from parts of the plant other than the radicle and are called adventitious roots. by subhrajyoti's horticulture
