Please mark me as brainliest only if this answer will help you

Explanation:

Following are the key difference between Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum (SER):

Smooth ER appears like containing many circular marks which are the interlocking tubular sheets, while Rough ER looks like the arrangement of the double membranes which are spotted with the ribosomes all over. RER appear like consisting of the parallel sheets of membrane.

Smooth ER is found near the cell membrane and Rough ER is found near the cytoplasm of the eukaryotic cells.

Smooth ER originates from rough endoplasmic reticulum by giving off the ribosomes, while Rough ER originates from nuclear membrane.

The main difference lies between the SER and RER is the presence of ribosomes, as SER do not have ribosomes but RER have ribosomes.

SER mainly produce and export lipids and protein and function for detoxification, while RER produces, secrete and export proteins and few hormones.

Answer 2

$\huge\bf{Answer :}$

1) RER ( Rough Endoplasmic Reticulum )

• It consists of ribosomes which are joint to it's membrane.
• Cisternae and few tubules have contributed to it's formation.
• It contributes in the formation of lysosomes.
• It actively participates in the formation of enzymes and proteins.
• It supplies proteins and lipids for Golgi Apparatus.

2) SER ( Smooth Endoplasmic Reticulum )

• It does not contains ribosomes with it.
• Vesicles and tubules have contributed to it's formation.
• It contributes to the formation of Oleosomes or spherosomes.
• It actively participates in the formation of steroids , lipids or glycogens.
• It supplies vesicles for cisface of Golgi Apparatus.
