Cells of these tissues have no power of division.

Cells are well developed and properly shaped.

Cell wall is comparatively thick.

Nucleus of the cells are bigger and cytoplasm is dense.

Usually there are vacuoles in the cell.

There may have intercellular spaces in between cells.

Answer and explanation

    Tissue is a cellular organisational level between cells and a complete organ. Example xylem and phloem.

The permanent tissues in a plant are those tissues that contain non dividing cells. Permanent plant tissues are found in mature plants.

  13. Their cells are well differentiated and are found in a diversity of shapes.
  14. Metabolic activities are comparatively slow.
  15. The metabolic activity is low in these cells compared to meristematic tissues.
