Endoplasmic Reticulum : Basics and Functions
According to Dallmer (1966), Endoplasmic Reticulum is originated from the plasma membrane by the investigation. According to Derobertis (1970), the ER originates from the nuclear envelope. The Endoplasmic Reticulum (ER) is a strikingly complex structure within the cell and has three morphologically distinct regions: Sheets of the nuclear envelope A network of interconnected peripheral ER tubules Peripheral ER sheets […]
