Explanation:
The network of membrane-enclosed tubules and sacs with an interconnecting network that is responsible in protein synthesis is called reticulum.
The ER becomes flattened as it spreads throughout, it helps in carrying out a lot of protein synthesis.
The ER are of 2 types:
The rough ER: The outer surface is covered by large number of ribosomes and is responsible in production of proteins.
The smooth ER: It is not connected with ribosomes and is responsible in functioning lipid instead of production of protein, metabolism.
