What is Endoplasmic Reticulum(ER) ? Name its types?
The cell organelle, Endoplasmic reticulum
(ER) is an extensive, interconnected, membrane- bound network of tubes and sheets. It consists of various channels like cisternae, vesicles and tubules.
ER carries materials throughout the cell.
There are two type of ERs:
Rough Endoplasmic Reticulum (RER) - bears ribosomes, involved in protein synthesis.
Smooth Endoplasmic Reticulum (SER) - Does not bear ribosomes, involved in lipid synthesis.
