Describe the structure of collenchyma tissue.

Answer: Collenchyma tissue is a living, flexible, simple permanent tissue.

A group of cells along with intercellular substances that perform a specific function is called tissue. The tissues that are completely grown and have lost the ability of division are known as permanent tissues.

Simple Permanent Tissue

Homogeneous tissues are another name for this type of tissue. They are made up of a single cell type, which has the same origin, structure, and function in most cases.

Simple permanent tissue is divided into three categories:

  • Parenchyma
  • Collenchyma
  • Sclerenchyma


  • Cells are long and thick-walled.
  • The cell wall is made up of cellulose and pectin.
  • It is the only tissue with the highest refractive index due to the presence of pectin.
  • It is found in the epidermis and the vascular bundle of dicot leaf.
  • The amount of chloroplast is less in the cells.
  • The cells have no intercellular spaces.
