What is Endoplasmic Reticulum Made up of
The endoplasmic reticulum is made out of a lipid
membrane. The endoplasmic reticulum is still
connected to the nuclear membrane that is wrap
around the cells DNA. So there is a straight
connection between the cells nucleus and the
endoplasmic reticulum.

Where is it situated in the Cell

• The rough endoplasmic reticulum is located around
  the nucleus in the cells of both plants and
  animals. It function and transports proteins and
  lipids throughout the cell.
• The smooth endoplasmic reticulum is connected to
  the nuclear envelope of cells in plants and
  animals. It's primary function is to facilitate
  the metabolism of carbohydrates and steroids in
  the cell

What is its function
The endoplasmic reticulum is a eukaryotic
organelle that forms an interconnected network of
tubules, vesicles, and cisternae within cells.
Rough endoplasmic reticula synthesize proteins,
while smooth endoplasmic reticula synthesize
lipids and steroids, metabolize carbohydrates and
steroids, and regulate calcium concentration,
drug detoxification, and attachment of receptors
on cell membrane proteins. Sarcoplasmic reticula
solely regulate calcium levels.
