Qauv Spirogyra - ib tug raug tus neeg sawv cev ntawm lub tuam tsev Green algae
Spirogyra hais txog lub Department of ntsuab algae. Nws lub cev yog ib tug filamentous thallus zoo, uas yog tsim los ntawm cov tug neeg lub hlwb thiab tsis tsim ntaub so ntswg thiab kabmob. Nws yog ib tug yam ntxwv feature ntawm tag nrho cov neeg ntawm cov pab pawg neeg ntawm sab nroj tsuag. Rau attaching rau lub hauv paus, raws li nyob rau hauv tag nrho cov algae, nyob rau hauv Spirogyra muaj rhizoids. Nrog rau cov formations filamentous thallus txuas mus rau lub substrate. Rhizoids tseem tuaj txuam nrog ntawm lub hlwb thiab tsis tsim ntaub so ntswg.
Spirogyra teej tug mus rau lub department Ntsuab algae txiav txim los ntawm lub xub ntiag ntawm chloroplasts nyob rau hauv lub hlwb ntawm cov nroj tsuag lub cev. Cov lug sawv cev rau ib hom ntawm plastids. Vim muaj cov chloroplasts Algae, zoo li tag nrho cov nroj tsuag, yog muaj peev xwm mus nqa tawm hauv tus txheej txheem ntawm photosynthesis - self-txoj kev carbohydrates yuav tsum tau rau txoj kev loj hlob thiab kev loj hlob.
Qauv Spirogyra hlwb
Qhov no sawv cev ntawm lub ntsuab algae yog ib tug multicellular kab mob. Spirogyra qauv (daim duab saum toj no qhia tau hais tias qhov yooj yim qauv) yog sawv cev los ntawm ib tug ntev filamentous qauv. Chloroplasts ntawm lub algae muaj rau hauv daim ntawv ntawm ib daim hlab, uas yog spirally qhwv. Qhov no feature, thiab qhia txog lub npe ntawm tus piav kab mob. Hlwb raug kuj elongated kom muaj ib tug cylindrical zoo. Lawv muaj kev cob cog los ntawm pores nyob rau hauv lub week, thiab los ntawm kev uas yog ua tus txheej txheem ntawm metabolism.
Zoo li tag nrho cov cog hlwb, feem ntau ntawm lawv nyob vacuoles sawv cev tso tsheb hlau luam sau nrog dej thiab yaj muab kev pab cuam. Plhaub impregnated carbohydrate cellulose, muab lawv lub dag lub zog thiab rigidity.
Alga Spirogyra, zoo li tag nrho cov nroj tsuag, yog ib tug eukaryotic kab mob. Qhov no txhais tau tias nws lub hlwb muaj ib tug nucleus. Lub organelle yog lub caj khoom muaj nyob rau hauv lub DNA molecules.
vaj tse
Alga Spirogyra nyob rau hauv feem ntau ntawm cov neeg mob yog ib qho cov neeg ntawm dej tsis qab ntsev lub cev ntawm sawv dej. Tab sis nws muaj raws li thiab nyob rau hauv lub seas. Nws xov, nws nyob rau hauv loj tus xov tooj, zoo li ntsuab wool, floating rau ntawm qhov chaw.
khoom noj khoom haus
Qauv Spirogyra txiav txim nws hom thiab lub hwj chim, vim hais tias lub hlwb comprise ntsuab algae chloroplasts plastids uas muaj peev xwm sawv ntawm photosynthesis. Nws essence lies nyob rau hauv lub tsim ntawm cov organic tshuaj los ntawm inorganic vim hnub ci tawg. Qhov no hom ntawm noj hu ua autotrophic.
Cov uas ua glucose algae yog siv rau qhov tseem ceeb heev muaj dab thiab kab txoj kev loj hlob. Ib tug tso oxygen yog yuav tsum tau los ntawm tag nrho cov uas muaj sia nyob rau kev ua pa - ib tug tsim nyog mob ntawm cov hav zoov nyob rau hauv lub ntiaj chaw. Yog qhov uas tus tshuaj tsim nyog rau photosynthesis, namely, dej thiab cov pa roj carbon dioxide, yog ncaj qha lawv tej vaj tse.
tu tub tu kiv
Rau no ntsuab alga yog predominant vegetative hais tawm qhov chaw ntawm lub thallus. Heev heev strands yog tawg rau hauv qhov chaw, txhua tus uas muab sawv mus rau ib tug tshiab kab. Qhov no ua rau cov kev siv thiab siab productivity ntawm tus txheej txheem. Txawm li cas los, tus qauv yuav ua rau nws ua tau rau Spirogyra thiab kev sib deev kev. Nws yuav siv sij hawm rau hauv daim ntawv ntawm conjugation. Yog li algae filaments yog intertwined, kev kawm tshwj xeeb tshwm sim therebetween - copulatory channel. Raws li nws lub internal txheem ntawm ib tug cell uas muaj caj ces cov ntaub ntawv uas ntws mus rau lwm lub. Cov no tsim ntawm ib tug kaw - zygospore. Nyob rau hauv lub xeev no, seaweed theem phiv tej yam kev mob, thiab nyob rau hauv lub caij nplooj ntoos hlav ntawm nws hlob hluas filamentous tshem me me.
Cov kev sib deev kev ua tau lub rov tshwm sim ntawm tshiab thaj chaw ntawm lub cev, uas yog ib qho kev cog adaptation rau hloov ib puag ncig tej yam kev mob.
Tus nqi rau ecosystems thiab tib neeg lub neej
Spirogyra qauv ua rau nws lub ntsiab yam khoom nyob rau hauv lub laboratory vim hais tias nws muaj ib tug kuj loj hlwb uas ncav cuag cov 0.01 hli nyob rau hauv txoj kab uas hla. Qhov no algae ntaub ntawv tuab thickets nyob rau hauv ntau reservoirs. Qhov no biomass yog tau faib ib tug txaus loj npaum li cas ntawm cov pa. Tab sis cov cuab yeej no yog ib tug tsis zoo nqi, raws li nws ua rau yus waterlogging kev ntawm lwj thiab algal blooms. Raws li ib tug tshwm sim, ntau yam tsiaj tej zaum yuav tsuas tuag. Yeej cov lus ntawm ib tug me nyuam txoj kev song "sucked rau xim av expanse ntawm ancient cov av nkos pas dej" yog mob siab rau ntsuab filamentous pawg Spirogyra. Txawm li cas los, vim nws tau cawm ib tug loj tus naj npawb ntawm dej lub neej, thiab biomass, uas nws tau tsim, ob peb lub sij hawm tshaj zoo xws li cov cim qhia tias terrestrial nroj tsuag.
Spirogyra yog ib tug raug tus neeg sawv cev ntawm cov pab pawg neeg ntawm sab nroj tsuag - namely, lub Department of ntsuab algae. Nws ua hauj lwm pab ib feem ntawm ecosystems ntawm zoo siv tag nrho cov dej tsis qab ntsev, qhov ntawm cov organic teeb meem thiab oxygen.
