PRESENTATION OUTLINE
FUNCTIONS
- the ER functions as a packaging system It does not work alone
- The ER works closely with the Golgi apparatus, ribososmes, RNA, mRNA, and tRNA.
- It creates a network of membranes found through the whole cell
The general structure of the endoplasmic reticulum is an extensive membrane network of cisternae (sac-like structures) held together by the cytoskeleton.
ROUGH ER LOOKS LIKE SHEETS OF BUMPY MEMBRANES WHILE SMOOTH ER LOOKS MORE LIKE TUBES
The ER may also look different from cell to cell, depending on the cell's function.
Smooth ER It acts as a storage organelle. It is important in the creation and storage of steroids.
