Simple tissues are of three types namely parenchyma, collenchyma and sclerenchyma.

  1. Parenchyma – they are living cells and walled, soft in nature due to the presence of thin-walled cells.
  2. Collenchyma – These are characterized by uneven thick-walled living cells. This unevenness in the thickening of the cell walls imparts partially hard giving mechanical support derived essentially from the elongated cells of the ground meristems, procambium sometimes.
  3. Sclerenchyma – They have cells with thickened lignified walls, providing them strength and making them waterproof.
