11 Important Functions of Endoplasmic Reticulum (ER) Class 9

11 Important Functions of Endoplasmic Reticulum explained with diagram for class 9

11 Important Functions of Endoplasmic Reticulum are as follows

  1. The Endoplasmic Reticulum (ER) is the site of protein synthesis and modification, and also the synthesis of lipids for new membranes. 
  2. It forms the supporting framework of the cell and also serves as a pathway for the distribution of the materials from one part of the cell to the other.
  3. Ribosomes present in all active cells act as sites for protein synthesis. Proteins manufactured here are transported throughout the cell by Endoplasmic Reticulum.
  4. Fat and lipid molecules manufactured by Smooth Endoplasmic Reticulum (SER) helps in building cell membrane and other cell components. This process is called membrane biogenesis.
  5. Some other proteins and lipids synthesized byEndoplasmic Reticulum(ER) function as enzymes and hormones.
  6. Smooth Endoplasmic Reticulum(SER) plays a crucial role in detoxification of poisons and drugs in liver cells of vertebrates (group of animals).
  7. It forms a network system, providing channels for the transport of materials, especially proteins.
  8. It transports between various regions of the cytoplasm or between the cytoplasm and the nucleus mainly.
  9. Endoplasmic Reticulum (ER) functions as a cytoplasmic framework.
  10. Endoplasmic Reticulum (ER) provides a surface for some of the biochemical activities of the cell.
  11. It gives mechanical support to the cells.
