The cell theory states that cells are the basic unit of life, new cells are formed from existing cells, and cells and their products make up living organisms. Evidence for the cell theory came from early microscope observations by Hooke, van Leeuwenhoek, and others showing the presence of cells.

Cell Theory (3-1) Four basic concepts of the cell theory Cells are the building blocks of all plants and animals. Cells are the smallest functioning units of life. Cells are produced through division of preexisting cells. Each cell maintains homeostasis.
