CAS BI 108 Lecture Notes - Apicomplexa, Artemisinin, Ciliate
Document Summary
Life cycles: asexual reproduction common, sexual reproduction may occur when conditions deteriorate, some life cycles simple, many extremely complex, ecological importance, protists are of enormous ecological importance! Feed on other organisms: could be split into as many as a dozen kingdoms, the scheme chosen for this discussion is based on modes of nutrition (how they feed themselves, eukaryotic supergroups, archaeplastids. Land plants: chromalveolates, excavates, amoebozoans, rhizarians, opisthokonts. Heterotrophs: zooflagellates amoeboids foraminferans radiolarians cilates sporozoans plasmodial + cellular slime molds. Saprotrophs: water molds, archaeplastids green algae, where land plants have their origins, about 7,500 species, variety of environments: oceans, freshwater, snowbanks, tree bark, turtles backs, many symbiotic with fungi, plants, or animals, morphology varied: Store excess food as starch: archaeplastids red algae, multicellular; red, green; about 5,000 species, marine, mostly in warmer seawater, some as deep as 200 m, some filamentous, most branched, feathery, flat, economic importance:
