The cell theory states that: cells are the fundamental building blocks of all living organisms (ie all living organisms are composed of cells) unicellular organisms are composed of one single cell (eg bacteria) and therefore are the smallest type of organisms possible.

Activity 1 evidence for cell theory read the cell theory timeline website, about robert hooke and the others involved in the development of the cell theory. The focus of this investigation of cell theory is to see how microscope images provide evidence to support the theory and how some notable exceptions challenge it cell theory was an important step in our understanding of living things it paved the way for robert koch and louis pasteur to establish the germ theory of disease two hundred years after the establishment of cell theory. Cells are the basic unit of life the smallest living thing is a cell and all life is made of cells ( schwann and schleiden) cells are the basic unit of structure as all tissues are made of one kind of cell working together towards one specific function cells arise from pre-existing cells (virchow.
