Question

Rough endoplasmic reticulum structure and characterstics

Answer 1

$\huge\boxed{\fcolorbox{white}{pink}{answer}}$

Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. Protein molecules are synthesized and collected in the cisternal space/lumen.

Answer 2

Rough endoplasmic reticulum :

Rough endoplasmic reticulum or RER is largely made of sheets a two dimensional array of flattened sacks that extend across the cytoplasm in addition to ribosomes these membrane contains an import protein complex that's called as translocon which is necessary for protein translation with RER. It breaks compond sugar into simple sugar ... RER is an organelle found in eukaryotic cells it function is to produce protein it is made up of cisternae , tubles and vesciles. The cisternae are made up of flattened membrane disks which are involved in modification of protein.
