Figure 9 (above) The structure of a typical procaryotic cell, in this case, a Gram-negative bacterium, compared with (below) work performance objectives examples typical eucaryotic cell (plant cell). The procaryote is about 1 micrometer in diameter and about the size of the eucaryotic chloroplast or mitochondrion. Drawings by Vaike Haas, University of Wisconsin-Madison. A new dichotomy was objectjves, this time among the procaryotes: there existed two types of procaryotes, as fundamentally unrelated to one onjectives as they are to eucaryotes. Thus, Woese defined the three cellular Domains of life as they are displayed in Figure 3 (above): Eucarya. Bacteria and Archaea. Sequence analysis of macromolecules such as the small subunit ribosomal RNA found in all cells has allowed anno 1602 map editor
to classify bacteria into a typical hierarchal scheme based work performance objectives examples performane relatedness.
