In the previous segment of the chapter ‘Cell Structure and Functions’, we learnt about the Nucleus. In this segment, let us get ourselves introduced to the cell organelle, Endoplasmic Reticulum.
What is Endoplasmic reticulum?
The transportation system of the cell which carries out various important functions is called the
Endoplasmic Reticulum (ER).
It is a long tube which is bound by a membrane. This tube is placed around the nucleus and moves outward throughout the cell.
There are two distinct types of tubes in this network:
- Rough Endoplasmic Reticulum (RER) – This part of the tube has some granular structures attached to it called the Ribosomes. The tubes of RER appear rough due to ribosomes.
- Smooth Endoplasmic Reticulum (SER) – This part is a plain tube. It lacks ribosomes and so the tubes of this part appear smooth.
