1.6: Classification System
1.6.1: Three Domains of Life
Read this page to review the three domains of life. Microscopic forms of life can be found in all three domains.
Read this page. Genetic data indicate DNA transfer between species to some extent.
1.6.2: Prokaryotes and Eukaryotes
- Read this page to review the prokaryotic and eukaryotic cell structure.
Complete this brief ungraded assessment. Remember that there are microbes among prokaryotes and eukaryotes as well.
1.6.3: Archaea
Read this page. Archaea adapt to diverse environments. Many archaea are extremophile, meaning they live in an environment that seems very hostile to the human eye.
Read this page. Note the molecular differences between the bacterial and archaea cell membrane and cell wall.
Read this page. Some archaea traits are similar to eukaryotes, while other traits are similar to prokaryotes.
1.6.4: Bacteria
Read this chapter to learn about the structure and function of bacterial cells. Make sure to click on the "Chapter Continued" link at the bottom of each page to move on to subsequent pages.
1.6.5: Eukaryotic Cells
Navigate your way through these slides on organelles by pressing "Next," located at the bottom of the slide frame. There are a total of 13 slides. There are eukaryotic microorganisms among fungi and protists.
