The Root Flashcards
the three types of roots
tap root system
fibrous root system
adventitious root system
which root system in found in dicots
tap root system
an example of a dicot plant in which tap root system is seen
mustard
which root system is found in monocots
fibrous root system
give an example of a monocot which has fibrous root system
wheat
examples of plants where adventitious roots are seen
grass
monstera
banyan tree
what are adventitious roots
roots that arise from parts of the plant other than the radicle
main functions of roots
absorption of water and minerals from soil
providing proper anchorage to the plant parts
storing reserve food material
synthesis of plant growth regulators
thimble-like structure the root is covered with at the apex
root cap
what does the root cap do
it protects the tender apex of the root as it makes its way through the soil
how are the cells of the region of meristematic activity
small, thin-walled and with dense protoplasm
what happens to the cells in the region of elongation
cells undergo rapid elongation and enlargement and are responsible for growth of the root in length
what happens to the cells in the region of maturation
after elongation, cells gradually differentiate and mature
from which region and which cells form root hairs
region of maturation
epidermal cells
what do these root hairs do
they absorb water and minerals from the soil
