ROOTS
External Structure of Roots
Oganization of root systems
Taproot
Penetrates deep in the soil
Fibrous root
does not penetrate deep in the soil
Aerial root
supplements the supply of moisture in the soil
Structure of individual roots
Individual roots
No lleaf
No axillary buds
No leaf scars
Internal Structure of Roots
Zone of Elongation
Function= great role in absorption that supports root growth
Zone of Maturation
Function= Absorption of water and minerals
Root Apical Meristem
Helps to be extended into mature root tissues
Mature Portions of the roots
Function= Keep water in for the further process of growth.
Root Cap
Function= Provides protection to the root apical meristem.
Origin And Development of Lateral Roots
Cell division in pericycle
Vascular Conncetion
Types of Roots And Roots Modifications
Storage Roots
Prop Roots
Areial roots of Orchids
Micorhizzae
Contractile Roots
Roots Modules and Nitrogen Fixation
#
Haustorial Roots of Parisitic Flowering Plants
Roots of Strangler Figs
Nitrogen Fixation
Chemical conversion of atmospheric nitrogen into usable compounds.
