A Correct answer
Explanation

Endoplasmic reticulum a system of membrane-enclosed channels which extends throughout the cytoplasm of the cell and interconnects with the plasma membrane and the nuclear envelope. Endoplasmic reticulum has several functions. Such as:

  1. It divides the cytoplasm up into interconnected compartments.
  2. Serves as routes for the transport of materials from one part of the cell to another.
  3. Plays an important role in the synthesis of proteins and some lipids.
  4. Responsible for generating new layers for Golgi bodies.
  5. Expanded regions of the endoplasmic reticulum may serve as storage areas.
