The basic units of structure for all living organisms are cells. All living things are made up of cells. Every
person, animal and plant, as well as tiny organisms that can only be seen under a microscope are made up
of cells. Living organisms may be made up of billions and billions of cells or a single cell.
The introduction of the term cell is credited to a physicist named Robert Hooke. The invention of the
microscope helped Hooke describe the cells of the bark of a tree and other plant cells. The term cell was
introduced by Hooke in 1665, because they reminded him of the tiny rooms or cells used by monks.
Cells are the basic units of life because cells make up all living things. Cells come from other cells,
meaning they can reproduce to create new cells of the same kind.
