Question

IV. (6 points; 1 point each) Choose the single most appropriate group of protozoans and algae to complete the following statements. Use each group onlv once. A. Dinoflagellates B. Red algae C. Diatoms D. Green algae E. Brown algae F. Diplomonads and parabasalids of the Excavata or Discoba clade 1. Greatest complexity of algal multicellular morphology and specialization, including internal transport tissue of "trumpet cells" (sieve cells), is found in this photosynthetic group 2. Non-flagellated members of unicellular phytoplankton community with cell walls of silica 3. Lineages of eukaryotes that include anaerobic parasites with non-functional mitochondria 4. Mostly marine algae; have chlorophyll a plus phycobilin pigments in their chloroplasts; source of agar and sushi wrappers 5. Includes flagellated unicells protected by cellulosic plates internal to the cell membrane; many capable of bioluminescence 6. Have the same photosynthetic pigments and chloroplast structure as land plants; examples include Volvox, sea lettuce (Ulva), and Chlamydomonas

Explanation / Answer

1- e The greatest complexity of algal multicellular morphology and specialization, including internal transport tissue of trumpet cells, is found in brown algae

2-c diatoms are the non flagellated members of unicellular phytoplankton community with cell wall of silica.

3- f diplomonads and parabasalids of the excavata or discoba clade are the leanage of eukaryotes that include anaerobic parasite with non functional mitochondria

6-d green algae has the same photosynthetic pigment and choloroplast structure as land plants, eg. Inude volvox, sea lettuce, and chlamydomonas

5- a dinoflagellates include flagellated unicells protected by cellulosic plates internal to the cell membrane; many capable of bioliminescence

4- b red algae are mostly marine algae, have chlorophyll a plus phycobilin pigment in their choloroplast; source of agar and sushi wrappers.
