Chapter Three: Cell Biology

Cytoplasm - Protein Producing Organelles - The Endoplasmic Reticulum

The endoplasmic reticulum
Spreading throughout the cytoplasm is the endoplasmic reticulum. It is a folded system of membranes that loop back and forth giving it a very large surface area. This membrane provides a surface area for cell reactions. It is also the Site of lipid production.

The E.R. comes in two forms:
  
Smooth E.R. has no ribosomes associated with it    The rough E.R. has ribosomes
