Cell Theory The work of these scientists provided information significant to the development of the cell theory All living organisms are alike because they are composed of cells … by studying the composition and chemistry of the cell, we understand the chemistry and composition of all kinds of life forms

Cell Organelles – Their parts, structure, and function
