This is a complex membranous system, which consists of two unit-membranes enclosing a narrow apace about 4mm wide. These form a network of interconnected channels that extends from cell membrane to the nuclear membrane.
Types
i. Rough Endoplasmic Reticulum.
ii. Smooth Endoplasmic Reticulum.
1. Rough Endoplasmic Reticulum
Numerous Ribosomes are present on this type of Endoplasmic Reticulum giving it a rough texture.
2. Smooth Endoplasmic Reticulum
These are free from Ribosomes.
Functions
a. Rough Endoplasmic Reticulum helps in protein synthesis.
b. Smooth Endoplasmic Reticulum is involved in lipid metabolism.
c. These also help in transport of materials from one part of the cell to the other part.
d. These also help to detoxify harmful chemicals that have entered the cell.
