Hint: Endoplasmic reticulum is a cell organelle that helps in the production and distribution of proteins in the cell and are together known as endomembrane systems. It is mainly of two types that are Rough endoplasmic reticulum and smooth endoplasmic reticulum. Here in the question they are asking about the part of the cell which is in continuation of endoplasmic reticulum.

Complete answer:
Cell contains so many organelles in it which helps in various functions. Endoplasmic reticulum is one of them. The endoplasmic reticulum is in continuation with the outer nuclear wall. The reason behind this is whenever a cell makes proteins, it transcribes mRNA from the DNA that is present inside the nucleus. The mRNA that is formed is then carried out of the nucleus into the rough endoplasmic reticulum. After it exits the nucleus, it binds with ribosomes and forms polypeptides.
Endoplasmic reticulum (ER) is basically composed of membranous sheets and tubules that start near the nucleus and stretch throughout the cell. The membranous sheets vary from cell to cell and the size and shape of the endoplasmic reticulum are dictated by the activity/function of the cell.

Therefore, we can conclude that the endoplasmic reticulum is in continuation with the “nuclear wall”.

Note:
The endoplasmic reticulum is of two types and it all depends on the presence or absence of ribosomes. If ribosomes are present on its surface then it is called rough endoplasmic reticulum (RER). And if ribosomes are not present on its surface then it is called a smooth endoplasmic reticulum (SER).
