CHAPTER 7A TOUR OF THE CELL
Section A: How We Study Cells
1. Microscopes provide windows to the
world of the cell
Cell biologists can isolate organelles to study
1838: Schleiden and Schwann proposed cell theory
These first three are the very basic foundations of Cell Theory. All six
of these components make up modern Cell Theory
1.Prokaryotic and eukaryotic cells differ in size and complexity
2.Internal membranes compartmentalize the functions of a eukaryotic cell
Fig. 7.4 The prokaryotic cell is much simpler in structure, lacking a nucleus and the other membrane-enclosed organelles of the eukaryotic cell.
