YChlorophyll vs Chloroplast
Photosynthesis yog lub teeb tsav cov tshuaj tiv thaiv uas hloov carbon dioxide thiab dej rau hauv lub zog muaj suab thaj. Photosynthesis yog pib los ntawm kev ntes lub teeb lub zog los ntawm chlorophyll pigments. Chloroplast yog qhov chaw uas photosynthesis tshwm sim.
YChloroplast
Chloroplast yog ib hom plastid organelle. Cov no muaj nyob rau hauv cov nroj tsuag hlwb thiab lwm yam photosynthetic eukaryotes. Chloroplast yog me ntsis zoo ib yam li mitochondria. Tab sis qhov txawv yog tias chloroplasts tuaj yeem pom tsuas yog hauv cov nroj tsuag thiab hauv protists. Chloroplast muaj chlorophylls, uas muab cov xim ntsuab rau cov chloroplast. Endosymbiotic txoj kev xav qhia tias chloroplasts hloov zuj zus los ntawm cov kab mob prokaryote (cov kab mob). Ntxiv nrog rau chlorophylls, chloroplasts kuj muaj carotenoids. Chloroplast feem ntau muaj 2 hom pigments. Ib hom yog chlorophyll, uas suav nrog chlorophyll a thiab chlorophyll b. carotenoids yog 2 hom. Cov no yog caroteine thiab xanthophyll. Chloroplast yog ib puag ncig los ntawm ob daim nyias nyias. Ib cheeb tsam tsis muaj xim hu ua stroma nyob hauv chloroplast. Cov kua dej puv daim nyias nyias khi lub hnab hu ua thylakoids khiav los ntawm stroma. Cov no yog tsim los ntawm cov pob zeb zoo li pob zeb hu ua grana. Cov grana no interconnected rau ib leeg los ntawm lamellae. Thylakoids (lamellae thiab grana) muaj cov xim photosynthetic. Stroma muaj enzymes, ncig DNA, 70s ribosomes thiab photosynthetic khoom (qab zib, starch nplej thiab lipid droplets). Photosynthesis muaj ob qho kev tshwm sim. Lawv yog cov tshuaj tiv thaiv lub teeb thiab qhov tsaus ntuj. Lub teeb tshwm sim tshwm sim hauv thylakoids (grana thiab lamellae). Tsaus tshwm sim tshwm sim nyob rau hauv lub stroma.
YChlorophyll
Chlorophyll yog xim ntsuab. Nws tuaj yeem pom hauv ntau yam kab mob xws li cov nroj tsuag, algae thiab cyanobacteria. Chlorophyll yog ib qho tseem ceeb tshaj plaws rau photosynthesis. Chlorophyll absorbs lub teeb nyob rau hauv xiav thiab liab cheeb tsam ntawm lub spectrum pom thiab muaj kev cuam tshuam xim ntsuab rov qab. Nroj tsuag, algae thiab prokaryotes synthesize chlorophylls. Muaj ntau hom chlorophylls. Cov no suav nrog chlorophyll a, chlorophyll b, chlorophyll c thiab chlorophyll d. Chlorophyll a yog qhov ntau tshaj. Chlorophyll muaj nyob rau hauv ntau hom uas muaj liab absorption ncov ntawm me ntsis sib txawv nthwv dej ntev. P700 hauv Diam duab system I thiab p680 hauv daim duab duab II yog ob qho piv txwv. Chlorophylls muaj cov yam ntxwv ntawm lub teeb haum (nws absorbs feem ntau xiav thiab liab lub teeb thiab pom lub teeb ntsuab). Chlorophyll molecule muaj lub taub hau hydrophilic thiab tus Tsov tus tw hydrophobic. Hydrophilic taub hau yog npaj rau sab nraud ntawm thylakoid membrane. Hydrophobic Tail yog npaj rau thylakoid membrane. Lub teeb ntes ib feem ntawm cov molecule feem ntau muaj alternating ib leeg thiab ob daim ntawv cog lus. (Electrons tuaj yeem txav tau yooj yim nyob ib ncig ntawm lub molecule). Cov ntawv cog lus no muaj cov khoom siv hluav taws xob uas muaj peev xwm txav mus rau qib siab zog los ntawm kev nqus lub teeb. Lub nplhaib muaj peev xwm muab lub zog hluav taws xob rau lwm cov molecules.
Qhov txawv ntawm Chloroplast thiab Chlorophyll yog dab tsi?
• Chloroplast yog ob daim nyias nyias khi plastid hom organelle, uas muaj thylakoids, stroma, ncig DNA, ribosomes thiab lipid droplets, whereas chlorophyll tsuas yog ib qho molecule.
• chlorophylls yog cov xim uas nqus lub teeb lub zog, thiab chlorophylls muaj nyob hauv chloroplasts.
• Chlorophylls yog cov molecules, uas pib photosynthesis los ntawm absorbing lub teeb lub zog, thiab chloroplasts yog qhov chaw ntawm photosynthesis.
