A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one unicellular to many trillions multicellular.

Cell biology is the study of cells, their physiology, structure, and life cycle. Teach your students about cell biology using these classroom resources. Scientists once thought that life spontaneously arose from nonliving things.

Thanks to experimentation and the invention of the microscope, it is now known that life comes from preexisting life and that cells come from preexisting cells. Cells function differently in unicellular and multicellular organisms. A unicellular organism depends upon just one cell for all of its functions while a multicellular organism has cells specialized to perform different functions that collectively support the organism.

From the single cells that make up the simplest organisms to the trillions of cells that make up the complex structure of the human body, each and every living being on Earth is made of cells. This idea is part of the cell theory and is one of the central concepts of biology. Cell theory also states that cells are the basic building blocks of living organisms and that all cells come from other cells. This knowledge is foundational today. Scientists did not always know about cells, though. The discovery of the cell would not have been possible if not for advancements to the microscope.

Interested in learning more about the microscopic world, scientist Robert Hooke improved the design of the existing compound microscope in His microscope used three lenses and a stage light, which lit up and enlarged the specimens.

These advancements allowed Hooke to see something amazing when he placed a piece of cork under the microscope. To him, the cork looked as if it was made of tiny pores, which he came to call "cells" because they reminded him of the cells in a monastery. Not long after Hooke's discovery, Dutch scientist Antonie van Leeuwenhoek detected other hidden, tiny organisms called bacteria and protozoa.

It was unsurprising that van Leeuwenhoek would make such a discovery. Mouse embryonic stem cell line established.
