Detailed explanation-1: -Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.

Detailed explanation-2: -The endoplasmic reticulum (ER) is a complex, extensive network that transports materials throughout the inside of a cell.

Detailed explanation-3: -Organelles, including the Golgi apparatus and endoplasmic reticulum, are responsible for the transport of different substances throughout the cell.

Detailed explanation-4: -The ER has been shown to be closely apposed to almost all membrane-bound organelles, including the PM, mitochondria, lipid droplets, Golgi, endosomes, and peroxisomes (Fig.

Detailed explanation-5: -The ER, Golgi apparatus, and lysosomes are all members of a network of membranes, but they are not continuous with one another. Therefore, the membrane lipids and proteins that are synthesized in the ER must be transported through the network to their final destination in membrane-bound vesicles.
