two types: smooth and rough
Smooth ER: (SER) lipid synthesis and Ca storage
Rough ER: (RER) ribosomes, protein synthesis, protein folding, protein glycosylation |

Definition
three major components: microtubules, microfilaments, intermediate fibers
three major roles: maintain cell shape, facilitate movement of cells (plants), and facilitates movements and trafficking within cell
microtubules (MT): girderlike protein tubes made of tubulin that are compression resistant
microfilaments: polymerized globular actin, tension within the cell, such as muscle contraction
intermediate fibers: IF proteins that connnect MT's and MF's to provide mechanical support |
