What is a Cell?
A cell is the basic structural and functional unit of life. All living organisms are made up of cells. Some organisms, such as Amoeba and Paramecium, consist of only one cell and are called unicellular organisms. Organisms made up of many cells, such as humans, animals, and plants, are called multicellular organisms.
The discovery of cells was made by Robert Hooke in 1665 when he observed thin slices of cork under a microscope.
