Document Summary

Kinesin: always moves away from the centriole. Don"t know: they have some set of instructions of the placement of structures, may be the answer to the protein first hypothesis. Flagellum in eukaryotes are different from the bacteria. Centrosomes are also the source of locomotion by pushing cell membrane. This is not amoebic motions, its cell gliding/creeping. Unikont: eukaryote that provided a wiggling projection from the body, created a water current to bring nutrients, animalia and fungi. Bikont: has two of flagella and used for motion into the photosynthetic zone, ingested photosynthetic organisms which ended up surviving, creating chloroplasts inside the eukaryote, plants. Eukaryotes ate each other, creating larger structures. Developed chlorophyll a and b in separate lines: cell that swallowed one a and one b making it a and b, where plastids came from. S much diversity but only 3 kingdoms really survived (animalia, fungi, plantae. Flagellar: 9+2 organization, flagellum are either bikont or unikont.
