The Root System and Its Types

  • The roots arise from the direct elongation of the radicle in the majority of the angiosperms.
  • Roots are positively geotropic, positively hydrotropic and negatively phototropic.
  • It is non-green and is not differentiated into nodes and internodes.
  • The direct elongation of the radicle produces primary root which grows inside the soil.
  • This primary root then bears lateral roots called secondary roots, tertiary roots etc. 

 

Adventitious Root System: In some plants like grasses, banyan tree, Monstera, etc. the roots arise from parts of the plant other than the radicle. These are called adventitious roots.
