Cells are the building blocks of life. According to Cell Theory, all living things are made of cells; cells are the basic unit of life; and all cells come from other cells. The nucleus of a cell has chromosomes made of DNA, which make each individual unique.

To understand why humans are the way they are, look at cells—especially the material in the center, called chromosomes. People have 23 pairs of chromosomes, so each cell has 46 in all. Parents pass chromosomes to their children. DNA carries the genetic information in alleles and is the blueprint for the cells of an organism. DNA tells one's body how to put certain materials together to produce certain traits.

British scientist Robert Hooke built an early microscope and was the first scientist to observe cells and give them their name. Anton van Leeuwenhoek created the best microscopes of his time and used them to study living organisms. Matthias Schleiden, Theodor Schwann, and Rudolf Virchow created Cell Theory, which says that all living things are made of cells; cells are the smallest part of a living thing; and all cells come from other cells.
