Rough Endoplasmic reticulum the structure

• The basic structure consists of sheets of
  phospholipid membrane, which ribosome's are
  attached to.
• Made up of a series of thin, intricate channels,
  and exists in the folds in the phospholipid
  membrane.
• Many ribosome's are attached to endoplasmic
  reticulum. These are small dense organelles,
  about 20nm in diameter.
• It also contains Cytosol, which is a solution
  containing enzymes.

Rough Endoplasmic reticulum the functions

• The narrow fluid-filled space between the
  membranes acts as a transport network which moves
  materials around the cell.
• The folded membrane of ER creates a large surface
  area.
• Ribosome's are the part of the RER which carry
  out protein synthesis. This is where RNA
  (produced by the nucleolus) binds to a ribosome,
  which uses the information encoded in the RNA to
  assemble amino acids in the correct order to
  produce the desired protein.
• The protein produce in RER is exported from the
  cell for use elsewhere
