The cell, first found by Robert Hooke around 1665, has a long and fascinating history that has led to most of today's scientific breakthroughs. Cell is a general term that refers to a single living entity within the body of an organism that has the capacity for growth and self-replication. In other words, inside each of us, there exist trillions upon trillions of tiny organisms that essentially regulate our entire lives. There are many things we don't know about cells yet, but hopefully this will help you understand what they are and how they work.
