Biology 201 Spring 2013 Todd Hennessey – Notes on Cells 1.1. The discovery of cells cells were discovered by Robert Hooke Theodor Schwann- concluded that the cells of plants and animals are similar structures  and proposed these two tenants of the cell theory All organisms are composed of one or more cell The cell is the structural unit of life  (added by Rudolf Virchow later on) cells CAN arise ONLY from division of preexisting  cells  1.2. Basic Properties of Cells life death- if something can die, it must be living to begin with cells are highly complex and organized  the more complex the structure and organized, the ore likely things are in their place  and less likely for errors each type of organelle has a consistent composition of macromolecules, which are  arranged in a predictable pattern. Information obtained by studying cells from one type of organism often has direct  application to other forms of life Many of the most basic processes, such as the synthesis of proteins, the conservation  of chemical energy, or the construction of a membrane, are remarkably similar in all  living organisms.
