Detailed explanation-1: -Without the endoplasmic reticulum, the cell will not survive. Without rough ER the cell will not be able to synthesize new lysosomal enzymes, plasma membrane proteins, proteins for Golgi apparatus, and proteins essential for extracellular secretion.
Detailed explanation-2: -The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins.
Detailed explanation-3: -The ER has a central role in lipid and protein biosynthesis. Its membrane is the site of production of all the transmembrane proteins and lipids for most of the cell’s organelles, including the ER itself, the Golgi apparatus, lysosomes, endosomes, secretory vesicles, and the plasma membrane.
