Who is credited with the discovery of the endoplasmic reticulum?

The discovery of the endoplasmic reticulum is credited to Porter and Thompson, who described the organelle in 1945. Later, in 1953, Porter coined the term "endoplasmic reticulum" to refer to this organelle. The endoplasmic reticulum is a system of membrane-lined channels found in all eukaryotic cells except adult erythrocytes. It plays a crucial role in the synthesis, folding, and transport of proteins and lipids in the cell. The discovery of the endoplasmic reticulum was a significant milestone in cell biology, contributing to our understanding of the complex organization and function of eukaryotic cells.
