The domain Eukarya encompasses a breathtaking range of size and form, from giant whales and sequoias to microbial fungi, algae, and protists. Some eukaryotic microbes are single cells as small as the smallest bacteria. Fungi include multicellular forms such as mushrooms, as well as unicellular yeasts and filamentous Penicillium and Neurospora. Fungal filaments interconnect the roots of forest plants, forming a vast underground network of nutrients. Algae conduct photosynthesis using chloroplasts. Algae include broad sheets of kelp as well as unicellular phytoplankton. Many algae turn out to be secondary endosymbionts— protists whose ancestors engulfed preexisting algae whole, only to assimilate them and utilize their prey’s chloroplasts. Protists include amebas, zigzag-swimming euglenas with their chloroplasts, paramecia with hundreds of cilia, and stalked vorticellae whose rings of cilia draw prey toward the mouth. Most protists are free-living, but some are deadly parasites, such as the trypanosome of sleeping sickness, and the plasmodium of malaria.

Organize

  1. Read the assigned sections from Chapter 20 in your text or ebook and review the bulleted “to summarize” lists that conclude each text section. This will provide an organizing framework for concepts introduced in lecture and help you take better notes.
  2. Use the flashcards to test your memory for new vocabulary terms.

Learn

  1. Take the diagnostic quiz to assess your understanding of basic concepts.
  2. Examine the diagnostic quiz feedback, then review your notes and re-read sections in your textbook or ebook that correspond to questions you missed.
  3. Study the Process Animations for this chapter. These animations bring key figures from the text to life, presenting key microbial processes in a dynamic format.
