Eukaryotic hlwb tau txais mitochondriathiab plastids los ntawm kev ua rau cov kab mob tsis muaj sia nyob thiab tsim kev sib raug zoo nrog lawv. Mitochondria tau muab los ntawm cov kab mob aerobic thaum choloroplasts tau muab los ntawm cyanobacterium.
Dab tsi yog muab los ntawm aerobic prokaryote?
Mitochondria thiab chloroplasts zoo li hloov zuj zus los ntawm engulfed prokaryotes uas ib zaug ua neej nyob ywj pheej. Qee lub sij hawm, eukaryotic cell engulfed aerobic prokaryote, uas tom qab ntawd tsim ib qho kev sib raug zoo nrog tus tswv tsev eukaryote, maj mam loj hlob mus rau hauv mitochondrion.
Cov pab pawg twg ntawm cov neeg tawm tsam tau muab los ntawm daim ntawv twg ntawm endosymbiosis?
Cov kws tshawb fawb kwv yees tias, hauv cov txheej txheem hu ua endosymbiosis, cov poj koob yawm txwv prokaryote engulfed ib photosynthetic cyanobacterium uas hloov mus rau niaj hnub chloroplasts. Molecular thiab morphological pov thawj qhia tias chlorarachniophyte protistsyog muab los ntawm qhov xwm txheej thib ob endosymbiotic.
mitochondria tuaj qhov twg?
Mitochondria hloov zuj zus los ntawm an endosymbiotic alphaproteobacterium (liab) nyob rau hauv ib lub archaeal-derived party celluas yog feem ntau ze rau Asgard archaea (ntsuab). Cov poj koob yawm txwv ntxov ntawm mitochondria (uas tsis yog poj koob yawm txwv ntawm ib qho alphaproteobacterium uas tseem tshuav) yog pre-mitochondrial alphaproteobacterium.
How aerobicCov kab mob tau engulfed los ua mitochondria thiab yuav ua li cas cov kab mob photosynthetic engulfed thiab nws thiaj li los ua chloroplasts?
Thaum qee lub sijhawm, eukaryotic cell engulfed tus kab mob aerobic, uas tom qab ntawd tsim kev sib raug zoo nrog tus tswv tsev eukaryote, maj mam tsim mus rau hauv mitochondrion. Eukaryotic hlwb uas muaj mitochondria ces engulfed cov kab mob photosynthetic, uas evolved los ua tshwj xeeb chloroplast organelles.
