Feem ntau ntawm cov nroj tsuag hauv ntiaj teb yog ntsuab. Cov no yog teb tsis kawg, meadows, hav zoov loj. Feem ntau los ntawm cov menyuam yaus koj tuaj yeem hnov cov lus nug: "Niam, yog vim li cas cov nroj tsuag ntsuab?". Wb sim teb lo lus nug no los ntawm qhov pom ntawm chemistry, physics thiab ib tug yooj yim layman.
Vim li cas cov nroj tsuag nplooj ntsuab? Tsuas yog hais txog complex
Cov nplooj thiab nyom ntawm peb lub ntiaj teb yog daj, liab, tab sis feem ntau ntsuab. Qhov no yog vim cov nroj tsuag xim me me pigments. Lawv nyob rau hauv lub hlwb ntawm txhua cov hniav ntawm cov nyom thiab nplooj. Ib txhia ntawm lawv muab cov nroj tsuag xim liab, lwm tus neeg daj, thiab tseem ntsuab. Feem ntau ntawm cov pigments yog chlorophyll, cov khoom uas muab cov nroj tsuag lawv cov xim ntsuab.
chlorophyll thiab photosynthesis yog dab tsi?
Nplooj thiab nyom yog xim los ntawm cov xim hu ua chlorophyll (ib yam khoom ntsuab uas koom nrog hauv cov txheej txheem ntawm photosynthesis). Yog li ntawd, cov as-ham raug tsim thiab tsim oxygen.
Ua tsaug rau lub teeb ntawm lub hnub, cov txheej txheem biochemical complex tshwm sim, vim li ntawdinorganic tshuaj thiab dej tau los ntawm cov nroj tsuag los ntawm cov av yog hloov mus rau hauv cov organic tshuaj (rog, carbohydrates, proteins, starch, qab zib). Lub ntsiab lus tseem ceeb ntawm photosynthesis yog cov nroj tsuag absorbs carbon dioxide thiab tsim oxygen, uas yog ib qho tseem ceeb rau lub neej ntawm tag nrho cov kab mob nyob rau hauv lub ntiaj teb no.
Physics thiab chemistry ntawm lub teeb ntsuab
Cia peb mus tob rau vim li cas cov nroj tsuag ntsuab.
Physicists piav qhia cov xim ntawm txhua yam khoom los ntawm ntau npaum li cas lawv nqus / pom lub teeb. Cov khoom nyob ib puag ncig peb muaj xim uas qhia txog lawv. Piv txwv li, yog hais tias ib yam khoom yog dawb, ces nws qhia tag nrho cov xim ntawm lub spectrum. Yog tias dub, ces txhua qhov ntxoov ntxoo yog absorbed los ntawm cov khoom no. Lub hnub ci dawb muaj xya xim uas txhua yam muaj sia nyob, cov nroj tsuag thiab cov khoom tsis muaj sia tau txais. Nyom thiab foliage ntawm tag nrho cov tones qhia tsuas yog ntsuab (nws tsis yog yuav tsum tau rau cov txheej txheem ntawm photosynthesis) thiab yog vim li cas tag nrho cov nroj tsuag muaj qhov ntxoov ntxoo. Thiab cov xim chlorophyll rho tawm lub zog rau kev loj hlob thiab khoom noj khoom haus los ntawm liab thiab xiav spectrum.
Cov kws tshawb fawb tuaj yeem piav qhia vim li cas cov nroj tsuag feem ntau pom lub teeb ntsuab es tsis txhob nqus nws. Txhua qhov xim ntawm cov spectrum muaj lub zog tshwj xeeb thiab cov duab ntawm photons (cov khoom me me ntawm lub teeb). Lub zog no yog qhov tseem ceeb rau photosynthesis. Qhov loj tshaj plaws ntawm photons muaj nyob rau hauv liab, thaum xiav muaj lub zog zoo tshaj plaws. Ntsuab photons tsis muaj zog thiab tsis muaj txiaj ntsig, yog li xwm tsis siv lawv.
Los ntawm qhov pom ntawm chemistry, txhua yam tau piav qhia txawv. Cov kws tshawb fawb ntseegtias cov xim ntawm cov khoom nyob ntawm qhov concentration ntawm qee yam hlau. Piv txwv li, ntshav liab vim tias hemoglobin hauv nws muaj hlau. Yuav luag tag nrho cov nroj tsuag yog ntsuab vim magnesium muaj nyob rau hauv chlorophyll. Qhov nthuav tshaj plaws yog tias qhov kev xav no tsis muaj pov thawj nyuaj. Cov kws tshawb fawb tau sim hloov magnesium nrog zinc, tab sis txawm tias qhov no, cov nroj tsuag tseem zoo li ntsuab.
Vim li cas nplooj tig daj thaum lub caij nplooj zeeg?
Vim li cas cov nyom tig daj thaum lub caij nplooj zeeg, nplooj qhuav thiab poob? Qhov no yog vim tsis muaj hnub ci. Thaum lub caij nplooj zeeg pib, cov hnub ua luv luv, txias dua thiab tsaus dua. Nroj tsuag yog rhiab heev rau qhov txo ntawm nruab hnub nrig teev. Chlorophyll tsis muaj xim ntawm lub hnub, thiab nws pib tawg, xim ntsuab ploj, tig mus rau xim av, liab, daj, crimson.
Vim li cas cov nroj tsuag tsis ntsuab?
Vim li cas hauv qhov, ntxiv rau ntsuab, muaj cov nroj tsuag ntawm lwm yam xim? Vim tias tsis yog chlorophyll, cov nroj tsuag tuaj yeem muaj ntau lwm cov xim. Piv txwv li:
- Anthocyanin yog cov xim uas nqus lub teeb ntsuab thiab cuam tshuam rau qhov seem. Cov nplooj uas muaj cov tshuaj yuav muaj xim tsuas yog ntsuab.
- Carotene yog cov xim uas qhia txog cov xim daj thiab xim liab. Nplooj thiab tshuaj ntsuab, uas cov carotene ntau dua li chlorophyll, yog liab lossis daj.
- Xanthosine yog ib yam khoom uas nqus tag nrho cov xim ntawm cov xim, tshwj tsis yog daj. Raws li, foliage muajxanthosine - daj.
Tam sim no nws yuav pom tseeb rau cov neeg laus thiab menyuam yaus vim li cas cov nroj tsuag ntsuab. Txhua tus neeg yuav nkag siab txog qhov tseem ceeb ntawm cov txheej txheem ntawm photosynthesis, yuav ua li cas cov nroj tsuag tau txais cov as-ham thiab loj hlob, thiab yog vim li cas lawv tig daj thiab wither nyob rau hauv lub caij nplooj zeeg. Tshawb lub ntiaj teb, nws nthuav heev!
