Permanent Tissue: Definition, Types and Characteristics

Permanent tissue: The kind of tissue in which the cells lose their dividing capacity after originating from meristematic tissue is known as permanent tissue. A group of cells which are similar in origin; similar in structure and similar in function are called simple permanent tissue.

Permanent tissues may be classified into three main groups: Simple, Complex and Special tissues.

Simple Tissues: They are homogenous and composed of structurally and functionally similar cells. These are of three types: Parenchyma, collenchyma and sclerenchyma.

Complex Tissues: The complex tissues are composed of different types of cells performing diverse functions. These are of two types xylem and phloem.

Special tissues: They are structurally modified and specially organized for secretary function.


  • Cells may be living or dead.
  • Cell walls may be thin or thick.
  • Both living and dead cells may be present in permanent tissue.
  • Nucleus is comparatively small.
  • Metabolic activities are relatively slow.
  • Intercellular space is present in between the cells.
  • Cytoplasm is comparatively little.
  • Cells may contain reserve, excretory or secretory substances.
  • Permanent tissue stored foods.
  • Chlorophylls permanent tissue produces food.
