Answer 2

Endoplasmic Reticulum -

• It is a well developed microscopic organelle of the cell.

• It is present in every cell expect prokaryotes and mammalian RBCs.

• ER is lipoprptenious and trilaminar like the Plasmalemma.

Types of Endoplasmic Reticulum -

• Smooth Endoplacmic Reticulum - Ribosomes are absent on the surface of SER.

• It plays an important role in manufacturing of lipids and fat.

• Rough Endoplacmic Reticulum - Ribosomes are present on the surface of RER.

• RER synthesis proteins with the help of ribosomes.
