Question

On what BASIS endoplasmic reticulum has been differentiated into two types? I AM ASKING BASIS PLS DONT TELL TYPES OF endoplasmic reticulum

Answer 1

$\large{\underline{\underline{\sf Endoplasmic \ Reticulum \ \colon}}}$

• Endoplasmic Reticulum is categorised into Smooth Endoplasmic Reticulum and Rough Endoplasmic Reticulum on the basis of presence of Ribosomes

• Under a microscope,the RER appears to be Rough and Granulated due to the presence of Ribosomes while SER is Agranulated and Smooth

• RER helps in production of Proteins while SER aids the production of Phospholipids

• Further ribosomes are of two types, namely 70S and 80S. Here, 'S' stands for Svedberg's Unit. It measures the sedimentation rate

• 70S ribosomes are found in prokaryotes and are made up subunits 50S and 30S

• While 80S ribosomes are found in eukaryotes with 60S and 40S as the subunits
