ENDOPLASMIC RETICULUM

STRUCTURE OF ORGANELLE

• E.R. can be either smooth or rough.
• If it's smooth, it acts as storage.
• If it's rough, it packages proteins. Some proteins stay in the cell, others get sent out.

TYPE OF CELL IT'S FOUND IN

• E.R. is found in all cells.
• It acts like the cell's brain.
• E.R. can look different in each cell depending on the cell's function.
• E.R. creates large networks of membranes for all across the cell.

FUNCTION

• E.R. stores stuff like proteins.
• It sends these proteins out to where where they need to go or keeps in stored for the cell it's in.
