Nyob rau hauv cov kab mob unicellular (ib leeg-celled) kab mob, diffusion hla cov cell membrane txaus rau muab cov pa oxygen rau ntawm tes. Diffusion yog ib qho qeeb, passive thauj txheej txheem. Txhawm rau ua kom muaj peev xwm muab cov pa oxygen rau hauv lub cell, tus nqi ntawm cov pa oxygen yuav tsum sib npaug ntawm qhov sib txawv ntawm daim nyias nyias.
Ua pa tshwm sim hauv cov kab mob unicellular zoo li amoeba li cas?
Kev ua pa hauv amoeba tshwm sim los ntawm yooj yim diffusion, cov pa oxygen yaj hauv dej lossis ib puag ncig ib puag ncig yog diffused rau hauv lub cell los ntawm cov cell membrane. Cov pa oxygen no yog siv rau kev ua pa metabolic. Cov pa roj carbon dioxide uas tsim tawm tau raug tshem tawm los ntawm qhov yooj yim diffusion mus rau ib puag ncig ib puag ncig.
Cov kab mob ib leeg yuav tsum ua pa?
Qee cov kab mob ib leeg tsis tas yuav ua pa kom muaj sia nyob … ntawm Israel's Tel Aviv University thiab kawm co-sau, hais rau Live Science. "Thiab tam sim no peb pom tias lawv tau poob lawv lub peev xwm ua pa. "
Cov kab mob ua pa li cas?
ua pa thiab ua pa | AMNH. Feem ntau cov tsiaj xav tau oxygen kom ciaj sia. Oxygen pab cov kab mob loj hlob, rov tsim dua, thiab hloov zaub mov mus rau lub zog. Tib neeg tau txais cov pa oxygen uas lawv xav tau los ntawm kev ua pa ntawm lawv lub qhov ntswg thiab qhov ncauj mus rau hauv lawv lub ntsws.
Cov kab mob me me tau txais cov pa oxygen li cas?
Nyob hauv cov kab mob unicellular, diffusion hla cov cell membrane txaus rau muab cov pa oxygen rau ntawm tes (Daim duab 20.2). Diffusion yog ib qho kev thauj mus los qeeb, passive.
