 Explanation:

The endoplasmic reticulum is a network of membranous tubules found within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane.

It is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, such as protein and lipid synthesis, folding, modification, and transport of proteins. It usually has ribosomes attached and is involved in protein and lipid synthesis. 

The endoplasmic reticulum is a type of cell organelle made up of two subunits –

the rough endoplasmic reticulum, and smooth endoplasmic reticulum.
