what are the characteristics of Parenchyma, Collenchyma, and Sclernchyma?

Features of parenchyma:

  • They form basic packing tissue.
  • Cells of this tissue are relatively unspecialised and may be oval, rounded or elongated in shape.
  • Their cell walls are thin.
  • These cells are living.
  • They show large intercellular spaces.
  • Cytoplasm is dense with a small nucleus.
  • The celss possess a large central vacuole.
  • Parenchyma provides support to plants and also stores food

Features of Sclerenchyma:

  • Their cells are dead.
  • Cells are long and narrow.
  • Cells are empty and devoid of protoplasm.
  • Cell walls are highly thickened due to lignin deposition.
  • There is no internal space inside the cell.
  • Cells are closely packed, with no intercellular spaces.
  • It is a strengthening or mechanical tissue.

Features of collenchyma:

  • They possess living cells.
  • It shows deposition of extra cellulose at the corners of the cells.
  • Intercellular spaces are generally absenjt.
  • Their cells are elongated in shape.
