Document Summary
Phyla rhizopoda (amoebas), euglenozoa, ciliophora, granuloreticulosea, and apicomplexa. Some behave like animals (heterotrophic, consume food, protozoans) See in these protists traits used in multicellualar forms. Important event: surrounding of nuclear material with membrane (nuclear membrane) Invagination inside and nuclear material in own environment. Important: internal environment is specialized for all things involved in making copies, transcribing etc. Invagination turned into er: secret passage way because of its origins seperate for cytoplasm to export things, enlarged membrane surface. Aerobic bacteria is incorporated in a euk cell and becomes specialized in breaking down pyruvate to carbon and make atp for the cell. Mitochondria is receiving pyruvate from the host cell and providing atp back to the cell. Was bacterium because it has its own dna (circular), membrane similar to bacterial membrane, has own ribosome and transcription and translation system. Second: take in photosynthetic bacterium (origins of plastid and chloroplast) Nuclear membranes: where they came, why appear, and structures/organization.
