Difference between collenchymas and sclerenchyma

Collenchyma

  • Collenchyma cells have thin primary walls with some areas of secondary thickening.
  • Collenchyma provides extra mechanical and structural support, particularly in regions of new growth.
  • It is in the form of oval, spherical or polygonal cells.
  • It provides mechanical support to the young growing parts of the plant.
  • Elongated cells are present. Less space is present between the cells.

Sclerenchyma

  • Sclerenchyma cells have thick lignified secondary walls and often die when mature.
  • It is in the form of sclereids and fibres.
  • It gives mechanical support to the plant organs.
  • It is found in wooden part or hard stem of the plant.
  • The cell wall is made up of lignin.
  • Sclerenchyma cells provide mechanical support to the plant as well as transportation of water and nutrients to the plants.
