Protistan Habitats,Origin of Eukaryotes,Endosymbiosis

Protistan Habitats
Most are aquatic. Make up plankton. Swim near waters surface. Some are symbiotic. From mutualism to parasitism. Malaria agent is protistan


Origin of Eukaryotes
Eukaryotes arise due to membrane bound nucleus, Endomembrane system, Mitochondria, Chloroplasts, Cytoskeleton, Multiple linear chromosomes and Complex life cycles

Endosymbiosis
Eukaryotes evolved from prokaryotes through gradually increasing levels of complexity. Mitochondria and Chloroplasts share prokaryotic characteristics. Circular DNA. Replicate through binary fission
