The Rough Endoplasmic Reticulum composed of - Cisternae Tubules Vesicles

The Rough Endoplasmic Reticulum composed of - Cisternae Tubules Vesicles Correct Answer All I, II, III

The correct answer is Option(4) .i.e.All I, II, III.    

  • The Rough Endoplasmic Reticulum composed of tubules, vesicles & cisternae. 
  • Endoplasmic Reticulum(ER): 
    • The network of membranous canals filled with fluid is called Endoplasmic Reticulum.
    • They are involved in transporting materials throughout the cell.
  • Functions of Endoplasmic Reticulum(ER): 
    • It is responsible for the synthesis of essential lipids such as cholesterol & phospholipids.
    • ER is associated with protein folding & protein synthesis.
    • It is also responsible for the metabolism of carbohydrates.
  • Types of ER: 
  • Rough Endoplasmic Reticulum: 
    • They are composed of vesicles, tubules, cisternae, etc elements.
    • These elements found throughout the cell and are involved with protein manufacture. 
  • Smooth Endoplasmic Reticulum: 
    • They are the storage organelle.
    • It is associated with the production of steroids & lipids.
    • It is also responsible for detoxifying the cell.
