Autotrophic kab mob: ntxwv nta thiab ua tau hauj

Autotrophic kab mob muaj peev xwm ua tau nws tus kheej kom muaj lub zog rau tag nrho lub neej muaj dab. Raws li lawv nqa tawm no transformations? Yuav ua li cas tej yam kev mob uas yuav tsum tau rau qhov no? Cia peb kawm saib.

autotrophs

Txhais los ntawm cov Greek "pib" txhais tau tias "tus kheej" thiab "trofos" - "zaub mov". Nyob rau hauv lwm yam lus, autotrophic kab mob neeg zog los ntawm tshuaj dab uas tshwm sim nyob rau hauv lawv lub cev. Tsis zoo li heterotrophs uas pub tsuas npaj organic tshuaj.

Feem ntau ntawm cov neeg sawv cev ntawm cov organic ntiaj teb no mus rau lub thib ob pab pawg neeg. Tsiaj txhu, fungi, feem ntau cov kab mob yog heterotrophs. Tsob nroj kab mob tsim organic teeb meem rau lawv tus kheej. Kab mob kuj yog ib cais nceeg vaj nyob rau hauv cov xwm. Tab sis ntawm tag nrho cov sijhawm uas muaj sia nyob, lawv yeej tsuas muaj rau cov me nyuam lawv tus kheej zoo los ntawm nws tus kheej-los ua ke. Ntxiv mus, ua rau sab nraum lub party kab mob, kab mob no kiag li txawm thiab tsis qhia tej yam tshwm sim ntawm lub neej.

nroj tsuag

Autotrophic kab mob yog feem ntau zaub. Qhov no yog lawv qhov tseem ceeb txawv feature. Organic tshuaj, nyob rau hauv particular zib monosaccharide, lawv tsim nyob rau hauv tus txheej txheem ntawm photosynthesis. Nws tshwm sim nyob rau hauv cog hlwb, nyob rau hauv tshwj xeeb organelles hu ua chloroplasts. Qhov no dvumembrannye plastids muaj ntsuab xim. Photosynthesis txaus tej yam kev mob kuj muaj cov tshav ntuj, dej thiab carbon dioxide.

Lub essence ntawm photosynthesis

Carbon dioxide nkag mus rau hauv ntsuab hlwb ntawm tshwj xeeb tsim - stomata. Lawv muaj xws li ob flaps uas yog qhib rau nqa tawm no. Therethrough thiab nkev pauv yuav siv sij hawm qhov chaw: cov pa roj carbon dioxide nkag mus rau hauv lub cell, thiab oxygen generated los ntawm photosynthesis, - cov ib puag ncig. Dhau li cov roj, uas yog ib tug yuavtsum tau kawm uantej rau lub neej, cov nroj tsuag tsim qabzib. Lawv siv nws raws li ib tug khoom noj khoom haus cov khoom rau hauv tus txheej txheem ntawm txoj kev loj hlob thiab kev loj hlob.

Ib txhij nrog tus txheej txheem ntawm photosynthesis, nroj tsuag tsis tu ncua ua tsis taus pa. Raws li cov ob tug opposing dab zaum yuav tshwm sim ib txhij? Nws yog qhov yooj yim. Tus txheej txheem ntawm kev ua pa yog tsawg mob siab heev tshaj photosynthesis. Yog li ntawd, cov nroj tsuag emit ntau oxygen tshaj carbon dioxide. Txawm li cas los, ib tug ntev lub sij hawm nyob rau hauv ib chav tsev tsaus nrog ib tug ntau ntawm cov nroj tsuag, ua tsis taus pa yuav tsis yooj yim. Qhov tseeb hais tias tus nqi ntawm cov pa yuav txo thiab cov pa roj carbon dioxide, on qhov tsis tooj, ua rau kom.

Nyob rau hauv kev, photosynthetic cov kab mob no muaj ib tug planetary tseem ceeb. Ua tsaug rau lawv, muaj lub neej nyob rau ntiaj chaw lub ntiaj teb. Thiab qhov no yog tsis yog ib tug rant. Tom qab tag nrho, lub neej yog tsis yooj yim sua yam uas tsis tau oxygen.

kab mob

Autotrophic kab mob thiab cov kab mob yog. Thiab nws tsis yog hais txog xiav-ntsuab algae, hlwb muaj cov ntsuab xim chlorophyll.

Muaj yog ib tug tshwj xeeb cov pab pawg neeg ntawm cov kab mob - chemotroph. Lawv muab siab npuab txoj organic tebchaw mus yooj yim, uas muaj peev xwm yuav absorbed los ntawm cov nroj tsuag. Nrog rau cov kev puas tsuaj ntawm cov tshuaj bonds yog faib ib qhov nqi ntawm lub zog uas chemotroph siv rau lawv livelihoods. Cov no muaj xws nitrogen-kho, hlau thiab leej faj cov kab mob. Piv txwv li, cov kab mob oxidize ammonia rau nitrite - ntsev ntawm nitric acid, ib tug leej faj compound - mus ntsev ntawm sulfuric acid, sulfates.

Tiam sis ntau tshaj feem ntau pom cov kab mob hom heterotrophic kab mob - saprotrophs. Rau lub hwj chim lawv siv qhov seem ntawm tuag kab mob los yog lawv metabolic khoom. Qhov no kab mob putrefaction thiab fermentation.

Nthuav yog lub fact tias nyob rau hauv cov xwm muaj cov tsis muaj tshuaj uas tus kab mob no yuav tsis tau phua.

Autotrophic kab mob yog tsis ib txwm muaj peev xwm ntawm txoj kev organic tebchaw. Heev feem ntau nyob rau hauv qhov xwm ntawm tus nyob tej yam kev mob ntawm cov kab mob sib txawv. Ces, cov dab ua tsis yooj yim sua. Autotrophs nyob rau hauv tus txheej txheem ntawm cov evolution nruj heev heev rau no nyob rau hauv lawv tus kheej txoj kev. Piv txwv li, ib leeg-celled tsiaj euglena ntsuab thaum lub sij hawm unfavorable lub sij hawm uas muaj peev xwm ntawm npaj noj organic tshuaj. Thiab thaum cov nyob tej yam kev mob yog normalized, nws mus rov qab mus rau photosynthesis. Tej kab mob no yog hu ua mixotrophy.

Autotrophic kab mob ua si ib qho tseem ceeb luag hauj lwm nyob rau hauv cov xwm, kev muab cov tej yam kev mob rau lub hav zoov ntawm tag nrho cov lwm yam kingdoms ntawm qhov.
