morphology of flowering plants
the root
the majority of dicotyledonous plants the direct elongation of radicle leads to formation of primary root - grow inside soil
It bears lateral roots of several orders that are secondary roots
Functions of root
- 2m
Absorption of water / mineral
anchorage
storing reserve food material
plant growth regulators
Types of roots
Tap root
primary root and its branches constitute tap root system - in dicots
ex : carrot and mustard
Fibrous root
replaced by large no. of roots from base of stemm and form fibres - monocots
Adventitous roots
it grows from any part of plant than radicle
ex : grass, banyan and potato
Regions of the root tip - 5m
Root cap
protect tender apex
region of meristematic
cells divide continously
region of elongation
rapid elongation / enlargement it is responsible for cell growth of root length
Region of maturation
they differentiate mature and origin of root hair ad branches
root hair abosrb water and nutrient
Modification of roots
support
storage of food
for respiration
