The endoplasmic reticulum (ER) is a membrane-bound organelle which helps in the synthesis and transportation of proteins. Rough endoplasmic reticulum (RER) has ribosomes attached to its surface and helps in protein synthesis. Smooth endoplasmic reticulum (SER) has no ribosomes attched to its surface. It helps in the manufacture of fat molecules, or lipids, important for cell function.
Lysosomes are associated with the disposal of cellular waste material.
