Question

Differentiate between rough ER and smooth ER.





​

Answer 1

Rough Endoplasmic Reticulum (RER)

Smooth Endoplasmic Reticulum (SER)

It possesses ribosomes attached to its membrane.

It does not have ribosomes on its membrane.

Formed of cisternae and a few tubules.

Formed of vesicles and tubules.

It participates in the synthesis of enzymes and proteins.

Synthesises glycogen, lipids and steroids.

It helps in the formation of lysosomes.

Gives rise to Spherosomes/ Oleosomes

It is internal and connected with the nuclear envelope.

It is peripheral and may be connected to plasmalemma.

Answer 2

$\large\purple{\underline{\rm{\star\:RER\::-}}}$RER help in transport of protein which are synthesised by ribosomes on their surface.

$\large\purple{\underline{\rm{\star\:SER\::-}}}$ SER to makes cellular products like hormones and lipids.

Hope it helps!!
