Reaon: Orgnaic acids yog decarboxylated thaum hmo ntuj. Dab tsi yog qhov photosynthesis adaptation ntawm C4 nroj tsuag thiab CAM nroj tsuag zoo sib xws? Yog vim li cas: Stomata ntawm CAM cov nroj tsuag qhib thaum nruab hnub.
Cov nroj tsuag CAM puas siv Rubisco?
CAM cov nroj tsuag ib ntus cais cov pa roj carbon monoxide thiab lub voj voog Calvin. … Cov organic acid khaws cia kom txog rau hnub tom qab thiab tom qab ntawd tawg, tso cov pa roj carbon dioxide uas tuaj yeem ua tau kholos ntawm rubisco thiab nkag mus rau Calvin lub voj voog ua suab thaj.
CAM cov nroj tsuag photosynthesize li cas?
Crassulacean Acid Metabolism (CAM) Photosynthesis
Nyob hauv txoj kev no, stomata qhib thaum hmo ntuj , uas tso cai rau CO2 kom diffuse mus rau hauv nplooj kom ua ke nrog PEP thiab daim ntawv malate. Cov kua qaub no ces khaws cia rau hauv lub hauv paus loj vacuoles kom txog rau thaum nruab hnub. Thaum nruab hnub, malate raug tso tawm los ntawm vacuoles thiab decarboxylated.
CAM photosynthesis tshwm sim nyob qhov twg?
Crassulacean acid metabolism (CAM) yog ib qho photosynthetic hloov mus rau cov dej tsis tu ncua, tshwm sim hauv cov nroj tsuag hauv arid cheeb tsam (piv txwv li, cacti) lossis hauv chaw sov epiphytes (piv txwv li, orchids thiab bromeliads).
CAM cov nroj tsuag nyob qhov twg khaws cov organic acids lawv ua thaum hmo ntuj?
Photosynthetic productivity nyob rau hauv CAM cov nroj tsuag yog txwv los ntawm qhov txwv tsis pub muaj peev xwm ntawm lub vacuole rau khaws cia cov organic acids thaum hmo ntuj. Kom kov yeej qhov notxwv tsis pub, CAM cov nroj tsuag tsim cov loj photosynthetic hlwb nrog loj vacuoles los txhim kho cov pa roj carbon cia. Cov hlwb loj no ua rau cov nplooj muaj succulent morphology.

Qhov twg hauv qab no yog piv txwv ntawm geotropism hauv cov nroj tsuag?
Lub ntsiab lus ntawm geotropism yog kev loj hlob ntawm cov nroj tsuag lossis tsiaj tsis tuaj yeem teb rau lub zog ntawm lub ntiajteb txawj nqus. Ib qho piv txwv ntawm geotropism yog cov hauv paus hniav ntawm cov nroj tsuag loj hlob mus rau hauv av.
Nyob rau hauv vernalisation flowering nyob rau hauv cov nroj tsuag yog?
Vernalization (los ntawm Latin vernus, "ntawm lub caij nplooj ntoos hlav") yoginduction ntawm cov nroj tsuag flowering txheej txheem los ntawm raug rau lub caij txias ntawm lub caij ntuj no, los yog los ntawm ib qho khoom sib npaug.
Nyob rau hauv cov nroj tsuag photoperiodic stimulus yog perceived los ntawm?
Photoperiodic stimulus yog pom los ntawm cov nploojthiab cov tshuaj floral yog tsim nyob rau hauv nplooj uas yog ces translocated mus rau lub apical tip, tom qab ua rau pib ntawm floral primordia. Photoperiodic stimulus yog dab tsi? Lub photoperiodic stimulus yog tau txais los ntawm nploojthiab pom meej kis mus rau qhov uas ua kom loj hlob mus rau hauv lub cev cia, xws li tubers thiab qhov muag teev.
Koj puas tuaj yeem tau txais cov amino acids los ntawm cov nroj tsuag?
Tsiaj zaub mov yog cov khoom muaj protein ntau tshaj plaws. Cov chaw cog qoob loo tsis muaj ib lossis ntau dua cov amino acids, uas ua rau nws nyuaj dua kom tau txais tag nrho cov amino acids uas koj lub cev xav tau. Yuav ua li cas vegans tau txais tag nrho cov amino acids?
Cov nroj tsuag sab hauv tsev hauv cov nroj tsuag?
Cov nroj tsuag zoo tshaj plaws hauv tsev muaj xws li hauv qab no: Aglaonema - Nws yog qhov txaus nyiam, zam lub teeb qis, thiab tsis loj hlob sai. Aspidistra - Koj yuav tsum tsis txhob muab dej ntau thiab nws yuav ua rau lub teeb qis. … Succulent - Nco ntsoov tias koj muab lub teeb ci rau lawv.
