Difference between endodermis and pericycle

Endodermis

  • In a plant stem or root, a cylinder of cells the separates the outer cortex from the central core.
  • The endodermis controls flow of water and minerals within the plant.
  • In most plants, this tissue is restricted to the roots.
  • The cells are barrel-shaped and due to the accumulation of starch it is also called starch sheath
  • It is in a plant stem or root, a tube of cells the separates the external cortex from the central core the endodermis controls flow of water and minerals within the plant.
  • Function: It acts as a stellar sheath and it also stores food.

Pericycle

  • In a plant root, the cylinder of plant tissue between the endodermis and phloem.
  • Pericycle may be composed of parenchyma cells or sclerenchyma cells or both.
  • Lateral branches and phellogen may arise from pericycle.
  • It is formed of alternate bands of parenchymatous and sclerenchymatous cells.
  • Pericycle generates cells of various kinds, including those that create lateral root development and enable secondary root growth.
  • Function: It stores all other food materials except nitrogenous foods.
