BIOL 111 Lecture Notes - Cyanobacteria, Convergent Evolution, Chlorophyll

Make a table, for the following groups to keep track of the following characters: Locomotion – 1 , 2, more flagella? Cilia? Cell structure – alveoli? cell wall? secreted skeleton? Feeding mode – photoautotroph, chemoheterotroph (predador, parasite)

Groups: Alveolates (Apicomplexans, Dinoflagelates, Ciliates), Stramenopiles (Oomycota, Diatoms, brown algae), Plantae: Chlorophytes, Rhizaria; Foraminifera, Radiolaria, Amoebozoans

1. Describe SAR eukaryotic supergroup. Please discussseveral examples, their distinguishing (unique) features, and thecomplex interactions that each example can have with humanbeings.
   1. SAR supergroup
      1. Stramenopiles(Brown Algae, Golden Brown Algae, WaterMold, and Diatoms)
      2. Alveolates(Dinoflagellates, Ciliates, andApicomplexans)
      3. Rhizarians(Foraminiferans and Radiolarians)

Match the following groups of organisms with the statements that best describe them. Use the letter that represents the group. Some groups are used more than once or not at all.

b. Proteobacteria

c. Unikonta

d. Cyanobacteria

e. Spirochetes

f. Diplomonads

g. Achaeplastida
