  1. How is the diversity within this group recognized, and what are the relationships among the subgroups? By: Katie Boudreau, Cosmo Kunzelmann, Heather Gosnell, and Leah Bilski

  2. Diversity in Eukaryotes -The word ‘eu-karyote’ literally means ‘true kernel’, in reference to the sequestering of the genome into the membrane-bounded compartment called the nucleus (Eukaryotes) -Display much greater degree of structural organization and complexity -Share several complex structural characteristics -Eukaryotes are both autotrophic and heterotrophic

  3. Different Forms and Functions • Protozoa are unicellular but perform and act as different structures such as • Skeletons • Sensory structures • Conducting mechanisms • Feeding structures • Special features of an organelle can be used to distinguish that organelle into a certain clade based on characteristics • Euglenozoa has nucleoli persist during mitosis • Apicomplexa: associated with anterior end present in developmental stages

  4. Subphylum Mastigophora • Unicellular, Flagellated • Class Phytomastigophorea (plant like-many contain chloroplast) • -Ex.Peranema, Phacus, Chlamydomonas, Gonium, Ceratium, Noctiluca, Eudorina, Pandorina • Class Zoomastigophrea • -Codosiga: collared flagellates (important in most primitive multicellular “animals”) • -Trypanosoma: sleeping sickness and chagas diseases • -Trichonympha • -Trichomonas: an STD • -Giardia: human intestinal parasite • http://www.microscope-microscope.org/applications/pond-critters/protozoans/mastigophora/mastigophora.htm

  5. Phylum Ciliates - Locomotion by cilia - Multilayered pellicle - Heterotrophic, many feeding modes - Two types of nuclei: macronuclei and micronuclei ~ 8,000 species - Reproduce sexually Types of Ciliates -Euplotes -Epistylis -Dileptus -Vorticella stentor -Acineta -Zoothamnium -Tetrahymena http://biology.unm.edu/ccouncil/Biology_203/Summaries/Protists.htm
