How would you describe the structure of the Endoplasmic Reticulum?

1 Answer

Structure of the endoplasmic reticulum is a network of membranes with either ribosomes present or absent.

Explanation:

Structure of the endoplasmic reticulum is a network of membranes. These network structures are interwoven together and form the cytoskeleton.
The phospholipid nature of membrane encloses the space or lumen. The spaces are continuous with the perinuclear space. On the basis of either ribosomes present or absent, the endoplasmic reticulums are following two types.
1. Rough endoplasmic reticulum-Ribosomes present and help in protein synthesis.
2. Smooth endoplasmic reticulum-The ribosomes absent.
