Nroj tsuag, algae, cyanobacteria thiab txawm tias qee cov tsiaj ua photosynthesis.
Hauv qhov no, hom kab mob dab tsi ua tawm photosynthesis?
Feem ntau cov nroj tsuag, feem ntau algae , thiab cyanobacteria ua photosynthesis; Cov kab mob no hu ua photoautotrophs. Photosynthesis yog lub luag haujlwm loj rau kev tsim thiab tswj cov pa oxygen ntawm lub ntiaj teb huab cua, thiab muab tag nrho cov organic tebchaw thiab feem ntau ntawm lub zog tsim nyog rau lub neej hauv ntiaj teb.
Qhov thib ob, cov kab mob twg ua tau oxygenic photosynthesis? Cov ntsiab cai dav dav ntawm anoxygenic thiab oxygenic photosynthesis zoo sib xws heev, tab sis oxygenic photosynthesis Nws yog feem ntau pom nyob rau hauv cov nroj tsuag, algae thiab cyanobacteria. Thaum oxygenic photosynthesis , lub teeb lub zog hloov hluav taws xob los ntawm dej (H2O) rau carbon dioxide (CO2), los tsim cov carbohydrates.
Tib neeg kuj nug, cov kab mob dab tsi ua cov txheej txheem ntawd?
Txhua yam muaj sia nyob ua pa. Cells xav tau thiab siv lub zog uas tsim los ntawm cov txheej txheem no los pab nrog kev ua neej kom cov kab mob ciaj sia thiab yug me nyuam. Cov pa roj carbon dioxide thiab cov pa roj carbon dioxide yog cov pa roj tseem ceeb uas cuam tshuam rau hauv aerobic ua pa.
Cov piv txwv ntawm Phototrophs yog dab tsi?
Piv txwv ntawm phototrophs / photoautotroph muaj xws li:
- Cov nroj tsuag siab dua (pob zeb cog, ntoo, nyom thiab lwm yam)
- Euglena.
- Algae (Green algae thiab lwm yam)
- Cov kab mob (piv txwv li Cyanobacteria)

Dab tsi yog cov txheej txheem uas tsim cov ntawv luam tshiab ntawm cov kab mob caj ces?
Cov txheej txheem ntawm DNA replication tsim ib daim qauv tshiab ntawm cov kab mob cov ntaub ntawv caj ces kom dhau mus rau lub cell tshiab. Dawb ntab nucleotides yog txuam nrog lawv cov lus qhuas los ntawm ib qho enzyme hu ua polymerase. Cov no yog 'lub tsev.' Lawv sib sau ua ke DNA tshiab strand nrog txhua tus qub strands
Dab tsi yog qhov cuam tshuam ntawm cov kab mob nroj tsuag uas rhuav tshem tag nrho cov chloroplasts hauv cov nroj tsuag?
Hauv cov xwm txheej ntxhov siab xws li drought thiab kub siab, cov nroj tsuag ntawm tes chloroplasts tuaj yeem ua rau puas tsuaj thiab tsim cov kab mob tsis zoo rau cov pa oxygen (ROS)
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Dab tsi yog qhov tseeb ntawm thaj chaw saum npoo rau qhov sib piv ntawm cov kab mob nyob?
Raws li qhov loj ntawm lub cev nce, nws thaj chaw saum npoo mus rau qhov sib piv qis. Qhov no txhais tau hais tias nws muaj qhov tsawg dua qhov chaw muaj rau cov khoom sib txawv, yog li tus nqi ntawm diffusion yuav tsis nrawm txaus kom tau raws li nws cov kev xav tau ntawm cov hlwb
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
