Monophyletic - Study guides, Class notes & Summaries

Endosymbiosis Ans: Organelles originated when a single-celled organism engulfed another single-celled organism • Usually obligate: the survival of one depends on the other the process in which unicellular organisms engulf other cells, which will then function as organelles within the host cell. Studies of DNA sequencing suggest that green and red algae developed when heterotrophic eukaryotes engulfed cyanobacteria. Algae Ans: -Eukaryotic • Aquatic • Photo-autotrophs • Unice...

Bio 114 Exam 2 Questions and Answers Already Passed What characteristic sets bacteria apart from archaea? Bacteria are distinguished by having peptidoglycan in their cell walls, a feature absent in archaea. How would you define a synapomorphy? A synapomorphy is a trait shared by members of a specific monophyletic group but not found outside that group. In ocean ecosystems, who are the primary producers? Photosynthetic protists are the main primary producers. Why are protists ...

species - evolutionarily independent population or group of populations synapomorphy - a trait that is found in certain groups of organisms and their common ancestor, but is missing in more distant ancestors; identifies monophyletic groups; homologous traits that can be identified at the genetic, developmental, or structural level biological species concept - reproductive isolation between populations (they don't breed and don't produce viable, fertile offspring) - reproductive isolation...
