$\underline{\boxed{ \rm \: Characteristics \: of Root}}$

1. Root is the descending or underground part of the plant axis.

2.Root is usually positively geotropic (i.e grows downward into the soil) and positively hydrotropic (i.e grows towards the source of water) but negatively phototropice ( i.e grows away from sunlight)

3. foot is usually cylindrical and non-green (i.e lack chlorophyll) but sometimes green as in Trapa and Taeniophylum.

4. Root does not bear nodes, internodes, leaves or buds (exceptions are sweat potato, wood apple etc.)

5. The growing point of root tip is subterminal and protected by a root cap or calyptra .

6.Unicellular root hairs present just behind the root caps which increase the absorptive surface area of roots.

7. Lateral roots are endogenous in origin ie arise from pericycle of the main root.
