Question

what is Endoplasmic reticullum and its types. explain

Answer 1

HII DEAR !!

@ENDOPLASMIC RETICULLUM :--

♦ these are the membrane bound channels seen in the form of a network of delicate strands and vesicles in the cytoplasm.

♦these are single membrane cell organelles.

♦these form an interconnected network of tubules ,vesicles and cisternae with in cells.

♦first observed by ::--⭐Porter , claude and full am in ( 1945 ) as a network.

♦present in almost all euaryotic cell.


@TYPES OF ENDOPLASMIC RETICULLUM :--

●smooth endoplasmic reticulum (SER)
●Rough endoplasmic reticulum (RER)

@smooth ER :-
==========
☆SER is an arrangement of tubules , vesicles and sacs.
☆there is are no ribosome's attached to the membrane surface.
☆The SER is connected to the nuclear envelope.
☆SER is less stable.

@Rough ER :--
==========
☆The surface of the RER is studded with ribosome ,giving it a rough appearance .
☆it is mainly consists of cisternae.
☆RER is very important in the synthesis and packaging of proteins .
