VOTE FOR SMOOTH AND ROUGH ENDOPLASMIC RETICULUM!!!

Cell_ER_labeled.jpg

The ER creates a chain of membranes throughout the entire cell
The cell wouldn't stand a chance without this packaging system!
The Smooth ER acts as a storage unit for steroids
The Rough ER has ribosomes attached to it and packages proteins
Some of those proteins are used in the cell but other are shipped out be delivered at another cell
Without the ER other cells couldn't have the proteins that they need to survive!
