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.
CHARACTERISTIC OF PERMANENT TISSUE
- Permanent tissues might be either simple or complex in nature.
- Cells of these tissues have no power of division.
- These tissues are derivatives of meristematic tissue.
- Cells are well developed and properly shaped.
- Cells or tissues may be living or dead and cell walls may be thin or thick.

- Inter-cellular spaces might be present or absent.
- There may have inter-cellular spaces in between cells.
- Their cells are well differentiated and are found in a diversity of shapes.
- Metabolic activities are comparatively slow.
- The metabolic activity is low in these cells compared to meristematic tissues.
- Vacuoles are prominent. Their cells show large vacuoles.
- They are mature tissue and the cell has lost the capacity of cell division.
