Document Summary
Cell cycle differs when the organism reproduces sexually or asexually. Differences are most obvious in the proportion of time spent as haploid versus. Lynn margulis (in 1967) resurrected this theory with new support from tem. No longer need a big genome since they are not independent (free-living: they are no longer their own organism, they now live in plant cells. This has happened at least three times that we know of so far : red algae, green algae, photosynthetic amoeba, these examples happen when it is beneficial for both organisms. Mitochondria: same process as chlorophyll but with proteobacteria except for a few extreme types in oxygen-poor environments. Nuclear genes of eukaryotes are loaded with other organism genes. Low oxygen plus hydrogen sulfide is a poor environment for eukaryotes but symbiosis with bacteria makes all the difference. Seven superkingdoms : opisthokonts, amoebozoans, archaeplastids, stramenopiles, alveolates, rhizarians, excavates. 150 species: not important to remember all the number of species for each.
