• Jakoba species
• Giardia intestinalis
• Trichomonas vaginalis
• Euglena

Question 2

supergroup Excavates : Distinguishing features

Answer 2

• Unicellular flagellates, often with a feeding groove.
• The euglenoids (many are photosynthetic) and
• diverse heterotrophic protists (some are parasites) are grouped with excavates.

Question 3

supergroup Land plants and relatives: KINGDOMS, phyla, classes, orspecies

Answer 3

• Rhodophyta (red algae)
• Chlorophyta (most green algae)
• KINGDOM PLANTAE and close green algal relatives

Question 4

supergroup Land plants and relatives: distinguishing features

Answer 4

• Land plants, green algae, and red algae have primary plastids derived from cyanobacteria.
• Cryptomonads (most of which possess secondary red plastids) and plastidless relatives

Question 5

supergroup Alveolata: KINGDOMS, phyla, classes, orspecies

Answer 5

• Ciliophora (ciliates)

Question 6

supergroup Alveolata: distinguishing features

Answer 6

• Peripheral membrane sacs (alveoli)
• Ciliates are distinguished by presence of cilia,
• some possess photosynthetic algal symbionts;
• Apicomplexa often have nonphotosynthetic secondary plastids;
