Answers
The root is normally an underground piece of the plant which helps in obsession and ingestion of water.
The root with its branches is known as the root framework.
Qualities of the Root
(I) The root is the diving part of the plant pivot and is decidedly geotropic.
(ii) It is non-green or darker in shading.

(iv) when in doubt the root does not hold up under leaves and genuine buds.
(v) Usually, the root tip is secured by a root tip.
(vi) The root bears unicellular root hairs.
(vii) Lateral roots emerge from the root which is endogenous in inception (emerges from pericycle).
Answer:
A root hair[1], or absorbent hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. As they are lateral extensions of a single cell and only rarely branched, they are visible to the naked eye and light microscope. They are found only in the region of maturation of the root. Just prior to and during root hair cell development, there is elevated phosphorylase activity.[2] Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. Another adaptation that they have is a large permanent vacuole.
hope it helps.....
thank me latter.... :-)
