Question
Be able to recognize pictures, drawings of common protists and structures on each. For example, know the following: Euglena, Paramecium, Amoeba, Volvox, diatoms, dinoflagellates. Know flagella, pseudopods, cilia, contractile vacuole, macro/micronuclei, test, eyespot (photoreceptor). Know some of the disease-causing protists. Know ecological importance of protists. Which supergroups belong to the bikonta? List the three supergroups and the distinguishing feature of each supergroup Describe the distinguishing features of the following three groups within the Unikont clade: Slime molds: Entamoebas Choanoflagellates: Which NON-protist group belongs to the bikont clade? Which NON-protist groups belong to the unikont clade? Are fungi more closely related to plants or animals? Explain.Explanation / Answer
Bikonta belongs to Eukaryotes. The three supergroups are: Excavata, SAR Clade, Archaeplastida.
Excavata are asymmetrical, single-celled organisms with a feeding groove. They include heterotrophic predators, photosynthetic species, and parasites. SAR Clade includes heterokonts, alveolates, and Rhizaria. Archaeplastida consist of red algae, green algae, land plants, and glaucophytes.
Slime molds have jelly-like protoplasm which contains nuclei. They are a mass of amoeboid cells. Entamoeba is anaerobic parasitic amoebozoan which causes amoebiasis. Choanoflagelates are free-living unicellular and colonial flagellate eukaryotes, closely related to animals.
