Keen & Dehesh S09 -2- 6 . Which of the following are possible life styles for ameobae? a) living at the bottom of ponds b) floating at the ocean’s surface in a tiny glass shell c) floating at the ocean’s surface in a tiny calcareous shell d) feeding on cornea tissue in the human eye e) all of the above 7 . What is the “slug” stage of a cellular slime mold life cycle? a) a stage where slugs are parasitized b) a large-scale dispersal stage made of many cells c) a dispersal stage that alternates with a flagellated phase d) a spore-generating phase of the life cycle e) a stage that forms when the environment is very good 8 . Define each of the following statements as true or false: All photosynthetic bacteria form a clade. False All photosynthetic eukaryotes form a clade. False The red algae belong to clade Plantae. True The chloroplast is a homologous feature for Clade Plantae. True, they all obtained the chloroplast from a single common ancestor. The chloroplast is a synapomorphy for Clade Plantae. False—there are other taxa with chloroplasts outside of Plantae—if you say True, you would have to be sure there were details of the chloroplast for this group that would allow you to distinguish this chloroplasts from those chloroplasts in other clades. 9 . Define each of the following statements as true or false: Plants fix nitrogen from the air. False Plants use bacterial symbionts ( Rhizobium ) to fix nitrogen from soil. False Plants use bacterial symbionts ( Rhizobium ) to fix nitrogen from air. True Plants use fungal symbionts (mycorhizae) to fix nitrogen from air. False Plants use fungal symbionts (mycorhizae) to fix nitrogen from soil.
