Solution:

ER is a single membrane-bounded structure that forms a channel-like structure in the cytoplasm. It consists of the empty lumen, luminal chamber, inside ER and extraluminal chamber, outside ER. SER carries out lipid synthesis and detoxification of toxic chemicals. It is a network of interconnected cisternae, tubules, and vesicles present in the endoplasm.
