The endomembrane system is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport proteins and lipids. It includes the endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, and the plasma membrane. These structures collaborate to perform various functions such as protein synthesis, sorting, and transport within the cell.
The endoplasmic reticulum (ER) serves as the transportation system in the cell. It is responsible for synthesizing proteins and lipids, and acts as a pathway for these molecules to move throughout the cell.

The endoplasmic reticulum and Golgi apparatus are often referred to as the cell's transportation system. The endoplasmic reticulum is involved in the synthesis and transport of proteins and lipids, while the Golgi apparatus processes and packages these molecules for delivery to their final destinations within or outside the cell.
The part of a cell that sends messages from the nucleus to the cytoplasm is the endoplasmic reticulum. It acts as a transportation system within the cell, facilitating the movement of proteins and other molecules between the nucleus and cytoplasm.
The function of cytoplasm within a cell is to provide a medium for the organelles to be suspended in and to facilitate various cellular processes, such as metabolism and transportation of molecules.
