Root System Video Lecture | Science & Technology for UPSC CSE

root system the underground part of
plant is called root system the
underground main axis of the plant body
is called root it is the prolongation of
radical of the embryo it is positively
geo tropic or negatively phototropic
it is not differentiated into nodes and
Internode's it is non chlorophyll as' or
brown colored it does not possess leaves
buds flowers and fruits lateral roots
are produced from main axis in a crop
Atal succession lateral roots are formed
from in the region of the main axis para
cycle so these are called endogenous
organs the small hair like outgrowth
present on the tips of lateral roots and
main axis are called root has root has
are exogenous organs root has are found
in Massa fights and Zehra fights and
absent in hydro fights the protective
layer present around the root tip is
called root cap root cap is made up of a
dead tissue called collector Jen hence
it is also called Culebra root cap is
well developed in Massa fights and zero
fights absent in hydro fights in
free-floating hydro fights root pockets
are present
types of root system
you
in angiosperms two types of root systems
are present they are one tap root system
two fibrous root system or advantageous
root system tap root system the central
main axis is called tap root tap root is
formed by the prolongation of radical of
the embryo lateral roots are produced
obliquely in all directions from tap
root in a crop Atal succession it is
most commonly found in dicotyledons
fibrous root system or adventitious
roots system a bunch of new roots are
produced from the base of the stem as
fibers so these roots are called fibrous
roots and the root system is called
fibrous root system in this roots are
not formed from radical so these are
also called adventitious roots and the
root system is called adventitious roots
system it is most commonly found in
monocotyledons functions of root system
roots provide Anchorage to the plant by
fixing it into the soil roots absorb
water and minerals from the soil roots
conduct the absorbed water and minerals
to the chute system
