Domains are larger than Kingdoms and are based on the kind of ____________ an organism has.

•What are the two broadest categories of the classification system????

DomainKingdom

How many domains are there?

3 Domains1.Bacteria2.Archea

3.Eukarya

•Domains are based on the characteristics of

1. Cell Type2. Cell Structure

•What are the 2 cell types again???

Domains

•Archaea and Bacteria are made up of unicellular prokaryotes

•Eukarya are made up of multicellular and unicellular organisms that have eukaryotic cells.

•The difference between Domain Bacteria and Domain Archaea is the cell structure.

•Domain Bacteria - the cell wall is made up of peptidoglycan.

•Domain Archaea - the cell wall DOES NOT have peptidoglycan

Polymer made of sugars and amino acidsfound outside the cell membrane in the cellwall in some bacteria = ______________PEPTIDOGLYCAN

http://www.scq.ubc.ca/?p=481

Peptidoglycan=Cell wall component.
