Autotrophs - yog tus kab mob uas muaj peev xwm ua ke lawv tus kheej organic teeb meem

Muaj ntau ntau taxonomic pawg uas muaj sia nyob. Qhov ntau yam nta raws li lawv cais. Ib tug ntawm lawv - lub hom ntawm lub hwj chim. Heterotrophs, autotrophs - yog dab tsi? Cov lus teb yog nyob rau hauv tsab xov xwm.

Muaj - mus nyob

Khoom noj khoom haus - ib qho ntawm lub ntsiab qhov zoo ntawm nyob kab mob. Dab metabolism thiab lub zog hloov dua siab tshiab, txoj kev loj hlob thiab kev loj hlob yog tsis yooj yim sua yam uas tsis tau txais daim ntawv ntawm cov as-ham. Cov neeg sawv cev ntawm txhua lub nceeg vaj ntawm qhov nyob rau hauv lawv tus kheej txoj kev nruj heev heev rau lawv kev npaj.

Hom khoom noj kab mob

Autotrophs thiab heterotrophs - cov no yog cov tseem ceeb ntawm kev kab mob nyob rau hauv cov zaub mov hom. Tus thawj ntawm cov no yog cov nroj tsuag thiab cyanobacteria, lub thib ob - tus tsiaj thiab fungi.

Heterotrophs tau noj xwb npaj tshuaj. Lawv yog cov organic (cov nqaijrog, lipids, carbohydrates) thiab inorganic. Piv txwv ntawm lub tom kawg yuav ua li mineral ntsev. Nyob rau hauv cov tsiaj, rau lawv cov hloov dua siab tshiab muaj kev tshwj xeeb lug ntawm txawv complexity ntawm lub koom haum. Protozoa xws li amoeba ciliate los yog muaj digestive vacuoles. Coelenterates Hydra hlwb muaj tib lub npe. Nyob rau hauv mollusks thiab arthropods muaj tshwj xeeb kabmob tshwm sim. Tab sis lub zoo meej tshaj plaws digestive system - nyob rau hauv cov tsiaj. Nws muaj tsis tsuas yog ntawm txoj kev, tab sis cov qog, enzymes uas pab splitting ntawm loj molecules ntawm biopolymers. Peb tsis xav tau no system, tsuas yog tus cab cab. Lawv muab lawv tus kheej mus rau lub plab hnyuv ducts thiab nqus twb ua zaub mov.

Autotrophs: nws yog dab tsi

Yog hais tias peb txhais no lub sij hawm los ntawm lub Greek lus, nws yog ib qho yooj yim to taub dab tsi yuav tsum tau tham. "Nws pib" txhais tau tias "tus kheej", "trofos" - "zaub mov". Thiab xwb, cov kab mob rau lawv tus kheej tsim rau lawv tus kheej cov kev tsim nyog cov ntaub ntawv uas.

Autotrophs - yog tus kab mob no, uas yog siv los tsim carbohydrate zog ntawm solar tawg. Tab sis tej yam tej yam kev mob uas tsim nyog rau qhov tshwm sim ntawm txoj kev no.

Lub essence ntawm photosynthesis

Qhov no txoj kev yuav siv sij hawm qhov chaw xwb nyob rau hauv lub ntsuab plastids - chloroplasts, uas yog lub luag hauj lwm rau cov uas tsim nyog xim ntawm tej yam tsob nroj kabmob. A yuavtsum tau kawm uantej no kuj muaj cov teeb, dej thiab carbon dioxide.

Nroj tsuag - qhov no autotrophs, uas nqa tawm ib tug tham tshuaj cov tshuaj tiv thaiv. Tab sis lub gist ntawm nws yog yooj yim: tawm ntawm cov dej thiab cov pa roj carbon dioxide yog cov carbohydrate piam thaj thiab oxygen. Lawv lub luag hauj lwm nyob rau hauv qhov mus overestimate cia li tsis yooj yim sua. Tom qab autotrophs - yog tus kab mob uas ua rau tau cov txheej txheem ntawm kev ua pa, thiab chaw pib lub hav zoov ntawm tag nrho lub neej nyob rau hauv lub ntiaj chaw.

Photosynthesis yog ib tug theej nyuab txheej txheem yuav siv sij hawm qhov chaw nyob rau hauv ob theem. Tus thawj yuav siv sij hawm qhov chaw nyob rau hauv lub teeb, lub thib ob - nyob rau hauv qhov tsaus ntuj nti, tiam sis tsis tas nyob rau hauv lub chloroplasts ntawm cov nplooj ntsuab. Carbon dioxide penetrates lawv los ntawm lub qhov nyob rau hauv lub cover ntaub, uas yog hu ua stomata. Lawv muaj peev xwm kuj tshwm sim kev ua pa thiab transpiration - evaporation ntawm cov dej los ntawm qhov chaw ntawm cov nroj tsuag.

Qabzib yog tau los ntawm photosynthesis, nws yog ib tug yooj yim carbohydrate - monosaccharide. Yog hais tias lub lwg me me ntawm lub substance yog kev cob cog rua pheej tsim complex biopolymer cov hmoov txhuv nplej. Nws yog nws leej twg nroj tsuag yog ncua raws li ib tug cia rau ib tug "rainy hnub." Qhov no piav qhia qhov tseeb hais tias tag nrho cov cog khoom noj nplua nuj nyob rau hauv carbohydrates uas yog ib qho yooj yim mus pib mus ua txhaum down twb nyob rau hauv lub qhov ncauj kab noj hniav.

Thiab ces tam sim ntawd rau lo lus nug tshwm sim: Yog autotrophs peb tus kheej kev ua pa? Tom qab no tus txheej txheem yog qhov fab ntxeev ntawm photosynthesis. Ntawm cov hoob kawm, yog, vim hais tias cov nroj tsuag - creatures. Ntawm daim card no yog hais tias tus nqi ntawm cov pa evolution ntawm ntau npaum li cas tshaj carbon dioxide. Txawm li cas los, Yog hais tias koj muab tso rau houseplants hauv tsev, qhov chaw uas tsis muaj tshav ntuj penetrates, lawv yuav cia li ua taus pa. Ua nyob rau hauv tej yam yog undesirable.

Leej twg yog chemotroph

Autotrophs - nws tsis yog tus tsuas yog pab pawg neeg ntawm cov kab mob uas muaj peev xwm ntawm nws tus kheej-ua rau nws tus kheej "zaub mov". Lawv yog ib hom ntawm chemotroph. Yog xav tau tus tsim nyog ntaub ntawv uas lawv siv yog tsis tshav ntuj, tab sis lub zog ntawm tshuaj bonds. Cov no muaj xws nitrogen-kho cov hauv paus hniav nodule kab mob uas tsim nyob rau hauv cov keeb kwm ntawm cov neeg sawv cev ntawm leguminous thiab cereal. Lug paub thiab leej faj cov kab mob.

Lawv oxidize tsim nyog tshuaj compound, thiab nyob rau lub resulting zog yog siv rau qhov tseem ceeb heev muaj dab.

Mixotrophy thiab complexity ntawm taxonomy

Tab sis muaj ib tug tshwj xeeb "lo qhia" cov kab mob no. Pom zoo cov tej yam kev mob rau photosynthesis tsis muaj ib txwm. Ntuj qhuav heev los yog tsis muaj lub teeb - ib tug loj heev lub chaw khuam siab rau nws cov chav kawm. Tab sis muaj mob ntawm tsis muaj npaj txhij-ua organic tebchaw. Nws yuav yooj yim heev yuav autotrophs thiab heterotrophs nyob rau tib lub sij hawm - los ua ib tug mix ntawm txoj kev muab. Tab sis yog nws tau? Ntawm cov hoob kawm. Mixotrophy - thiaj li yog cov neeg muaj tus kab mob uas muaj ob qho tib si chloroplasts, thiab muaj peev xwm mus nqus hauv lub tiav lawm cov ntaub ntawv. Ib tug piv txwv ntawm no - ib tug unicellular ntsuab euglena.

Carnivorous sundew tsob nroj, txawm li cas los, yeej autotroph. Thaum nws stands heterotroph noj nws cov prey ntawm ib tug tshwj xeeb trapping pab kiag li lawm.

Incidentally, nws yog lub hom zaub mov yog qhov tseem ceeb feature ntawm tej yam kab mob teej tug mus rau cov nroj tsuag los yog tsiaj cov zej zog. Piv txwv li, unicellular algae chlamydomonas txav nquag, ua tsaug rau lub xub ntiag ntawm flagella, thiab muaj ib lub teeb-sensitive qhov muag. Yuav ua li cas yog tsis ib tug tsiaj? Txawm li cas los, nws yog ib horseshoe cell chloroplast, uas txiav txim tias nws belongs rau cov nroj tsuag lub nceeg vaj.

Ib tug yooj yim dua lo lus nug yog nrog nceb. Lawv yog cov tsis muaj peev xwm sawv ntawm photosynthesis, muaj plastids thiab cov hmoov txhuv nplej tsis nteg nyob rau hauv khw. Tab sis daim ntawv txoj kev ua neej, unlimited kev loj hlob thiab muaj cov cell phab ntsa yuav tsis hu lawv cov tsiaj. Yog li ntawd, cov taxonomy txhais lawv nyob rau hauv ib tug nyias muaj nyias ib lub nceeg vaj.

Autotrophs - nws yog amazing kab mob. Raws li ib tug intermediary ntawm lub hnub thiab lub ntiaj teb, lawv ua lub neej tau rau peb ntiaj chaw.
