Root hairs do not contain chloroplast(plastid) because root hairs are present in dark and do not carry out the process of photosynthesis.

Root is generally non-green, underground, positively geotropic (only main root), positively hydrotropic and often negatively phototropic descending cylindrical axis of the plant body.
The root which develops from the radicle of the embryo is called primary root. Primary root bears lateral roots called secondary roots, which are further branched into tertiary roots and so on, e.g. many dicot plants.
Primary roots and its branches constitute tap root system. In monocot plants, the primary root is short lived and is replaced by a large number of roots originated from the base of stem and constitute the fibrous roots, e.g. wheat, rice, etc.
In grasses, Monstera and the banyan tree, roots arise from parts of the plant other than radicle and are known as adventitious roots. A typical root consists of a cap-like structure called root cap (root pockets in hydrophytes like Lemna, Eichhomia and Pistia) region, i.e. the region of meristematic activity, the region of cell elongation and region of maturation.
Root hair are found in the region of maturation, which absorb water and minerals from the soil.
