How is the function of the Endoplasmic Reticulum similar to a structure in a city?(Give an analogy.)

Explanation:

Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. Smooth ER (SER) acts as a storage organelle.

a adaptation is when organism changes itself to fit the environment
