When the cell was first discovered (and named) by Robert Hooke in 1665, it was hailed as a major discovery. However it was initially thought to be just a cell wall containing a mass of some sort of undifferentiated protoplasm.
It took years for scientists to learn just how complex that "simple cell" really was.
Gradually, they realized that even the standard animal cell contained many different highly specialized organelles-structures that perform various jobs inside cells. For example, these complex biological machines keep the cell healthy and thriving by handling critical manufacturing, processing, transportation, and communication functions for the cell. Even the cell wall turned out to be a very specialized structure. It admits or blocks the entry or exit of materials or molecular messages meeting very specific conditions, ready to perform very specific functions.
