Photosynthesis siv cov pa roj carbon dioxide uas tsim los ntawm txhua qhov ua pa kab mob thiab reintroduces oxygen rau hauv qhov chaw. Photosynthesis yog txheej txheem siv los ntawm nroj tsuag , algae thiab qee cov kab mob siv zog los ntawm tshav ntuj thiab tig mus rau hauv tshuaj zog.
Tsis tas li ntawd, cov kab mob puas siv photosynthesis?
Oxygenic cov kab mob photosynthetic ua photosynthesis zoo ib yam li cov nroj tsuag. Lawv muaj cov xim pleev xim rau lub teeb, nqus carbon dioxide, thiab tso pa tawm. Cyanobacteria lossis Cyanophyta tsuas yog daim ntawv ntawm oxygenic cov kab mob photosynthetic paub txog hnub no. Txawm li cas los xij, muaj ntau hom Cyanobacteria.
Ntsuab photosynthesis txawv ntawm cov nroj tsuag kab mob li cas? Lub ntsiab sib txawv nruab nrab ntawm cyanobacteria thiab lwm yam photosynthetic kab mob yog tias lwm cov photosynthetizers tsuas muaj ib qho photosystem, thiab lawv tsis tuaj yeem faib dej. Tsis-oxygen-evolving photosynthetic kab mob muaj bacteriochlorophylls thaum cyanobacteria (xws li nroj tsuag thiab algae) muaj chlorophylls.
photosynthesis ua haujlwm li cas hauv algae?
Photosynthesis yog cov txheej txheem uas cov kab mob siv lub hnub ci los tsim cov suab thaj rau lub zog. Nroj tsuag, cov algae thiab cyanobacteria txhua tus ua oxygenic photosynthesis 1, 14. Qhov ntawd txhais tau tias lawv xav tau cov pa roj carbon dioxide, dej, thiab hnub ci (lub hnub ci zog yog sau los ntawm chlorophyll A).
Qhov twg photosynthesis tshwm sim hauv algae?
Nyob rau theem cellular, cov tshuaj tiv thaiv rau photosynthesis tshwm sim nyob rau hauv organelles hu ua chloroplasts (hauv eukaryotic hlwb). Xiav-ntsuab cov algae (uas yog prokaryotic) nqa tawm cov photosythesis tshwm sim hauv cytoplasm.

Thaum ua qhov tshuaj ntsuam xiav dawb cov kab mob hauv cov kab mob muaj?
Hloov pauv, cov kab dawb dawb tsis tuaj yeem metabolize X-Gal los tsim cov xim xiav, vim tias lawv tsis tsim cov β-galactosidase ua haujlwm tom qab noj plasmid nqa cov DNA tso thiab cuam tshuam cov lacZ α noob. Cov kab mob dawb no muaj cov kab mob recombinant thiab yuav tsum tau xaiv (Daim duab 1)
Cov kab mob chemosynthetic txawv li cas ntawm cov kab mob photosynthetic?
Cov kab mob Photosynthetic yog cov kab mob hauv cov nroj tsuag ntsuab thaum cov kab mob chemosynthetic yog saprophytes ntawm cov khoom noj uas lwj. Lub zog ntawm lub hnub ci yog siv nyob rau hauv cov kab mob photosynthetic whereas nyob rau hauv chemosynthetic kab mob lub zog yog muab los ntawm oxidation ntawm inorganic tshuaj
Vim li cas lub stomata ntawm qee cov nroj tsuag suab puam kaw thaum nruab hnub?
Xws li cov nroj tsuag tau txais CAM photosynthesis thaum lawv qhib lawv lub stomata thaum hmo ntuj thiab coj hauv CO2. Stomata tseem nyob ze thaum nruab hnub los tiv thaiv kev poob dej los ntawm kev hloov pauv. Lawv khaws cov CO2 hauv lawv cov hlwb kom txog thaum lub hnub tawm los thiab lawv tuaj yeem nqa nrog photosynthesis thaum nruab hnub
Vim li cas algae tsis suav tias yog kab mob parasitic?
Vim li cas algae tsis suav tias yog kab mob parasitic? Algae yog cov autotrophs uas pom muaj nyob rau hauv subgroups Chromalveolata thiab Archaeplastida. Cov phab ntsa ntawm tes ntawm cov kab mob muaj chitin, algae tsis muaj chitin hauv lawv cov phab ntsa ntawm tes
Vim li cas cov roj yog kev kho mob zoo los tswj cov kab tsuag?
Cov roj muaj qhov sib txawv ntawm cov kab tsuag. Qhov tseem ceeb tshaj plaws yog tias lawv thaiv lub qhov cua (spiracles) los ntawm cov kab ua pa, ua rau lawv tuag los ntawm asphyxiation. Qee zaum, cov roj kuj tseem tuaj yeem ua cov tshuaj lom, cuam tshuam nrog cov kab mob fatty acids thiab cuam tshuam nrog cov metabolism hauv ib txwm muaj
