Question

what is the Structure of endoplasmic reticulum

Answer 1

$\bold{\displaystyle \rm\blue{Endoplasmic⠀Reticulum}}$

The endoplasmic reticulum is a large network of membrane bound tubes and sheets.

It looks like long tubules or round or oblong bags. The ER membrane is similar in structure to the plasma membrane.

There are two types of endoplasmic reticulum :

Rough endoplasmic reticulum (RER)

Smooth endoplasmic reticulum (SER)

$\underline\bold{\displaystyle \rm{RER:-}}$

RER looks rough under a microscope because it has particles called ribosomes attached to its surface.

$\underline\bold{\displaystyle \rm{SER:-}}$

SER look smooth under a microscope because it doesn't have particles called ribosomes attached to its surface.

Answer 2

Answer:

The general structure of the endoplasmic reticulum is a network of membranes called cisternae. These sac-like structures are held together by the cytoskeleton. The phospholipid membrane encloses the cisternal space (or lumen), which is continuous with the perinuclear space but separate from the cytosol.
