Chloroplasts ntawm cov nroj tsuag ntsuab nqus hnub ci thiab siv nws los tsim khoom noj rau nroj tsuag . Cov txheej txheem yuav siv qhov chaw ua ke nrog CO2 thiab dej. Absorbed teeb yog siv hloov cov pa roj carbon dioxide thiab lawv dhau los ntawm huab cua, dej thiab av li piam thaj.
Tom qab ntawd, ib tus tseem tuaj yeem nug, kev siv cov pa roj carbon dioxide hauv kev ua hluavtaws yog dab tsi?
Thaum txheej txheem ntawm photosynthesis , cev siv cov pa roj carbon dioxide thiab lub zog los ntawm Tshav kom ua suab thaj molecules thiab oxygen. Cov piam thaj molecules no yog lub hauv paus rau ntau complex molecules ua los ntawm cov photosynthetic cell, xws li qabzib.
Ib yam li ntawd, ob lub luag haujlwm tseem ceeb ntawm chloroplasts yog dab tsi? Chloroplast yog organelle pom nyob rau hauv nplooj ntawm cov ntoo ntsuab. Lawv pom nyob hauv cov cell cog. Ob txoj haujlwm tseem ceeb ntawm chloroplasts yog dab tsi? Ob lub luag haujlwm tseem ceeb ntawm chloroplasts yog tsim khoom noj (glucose) thaum lub sijhawm photosynthesis , thiab khaws cia zaub mov muaj zog.
Xav txog qhov no, cov txheej txheem twg siv cov pa roj carbon dioxide?
Cov pa roj carbon dioxide ua haujlwm tseem ceeb hauv cov txheej txheem tseem ceeb ntawm cov nroj tsuag thiab tsiaj txhu, xws li photosynthesis thiab ua pa. Cov txheej txheem no yuav piav qhia luv luv ntawm no. Cov nroj tsuag ntsuab hloov cov pa roj carbon dioxide thiab dej rau hauv cov khoom noj sib xyaw, xws li qabzib , thiab oxygen. Cov txheej txheem no hu ua photosynthesis.
Hom 2 hom twg muaj chloroplasts?
Chloroplasts yog organelles pom hauv cov cell cog thiab eukaryotic algae uas ua cov duab hluavtaws. Chloroplast nqus hnub ci thiab siv nws nrog dej thiab carbon dioxide gas los tsim zaub mov rau cov nroj tsuag.

Yuav ua li cas ob txheej ntawm cov nroj tsuag muaj chloroplasts?
Mesophyll hlwb (ob leeg palisade thiab spongy) yog ntim nrog chloroplasts, thiab qhov no yog qhov chaw photosynthesis tiag tiag tshwm sim. Epidermis kuj tseem ua rau thaj tsam qis ntawm nplooj (asdoes lub cuticle)
Nyob rau hauv cov nroj tsuag twg photosynthesis tshwm sim nyob rau hauv qia es tsis nyob rau hauv nplooj?
1 Teb. Nyob rau hauv cov nroj tsuag photosynthesis tshwm sim nyob rau hauv chloroplasts. Chloroplast tuaj yeem nyob hauv lub hlwb ntawm cov txiv hmab txiv ntoo, stems, tab sis feem ntau ntawm tag nrho cov nplooj. Hauv qee qhov succulents (xws li cacti), lub ntsiab photosynthetic kev ua haujlwm yog txuam nrog lub qia
Cov qauv twg tso cai rau cov pa roj carbon dioxide ntws mus rau hauv cov nroj tsuag?
Stomata (Yog lawm! Stomata yog microscopic pores nyob rau saum npoo ntawm nplooj uas cia carbon dioxide nyob rau hauv thiab oxygen thiab dej vapor tawm
Cov nplooj saum npoo ntawm thaj chaw cuam tshuam li cas rau kev txav ntawm cov dej los ntawm cov nroj tsuag?
Vim tias cov dej evaporates los ntawm ntau lub stomata ntawm nplooj nplooj, tus nqi ntawm transpiration yog ncaj qha cuam tshuam rau thaj chaw saum npoo
Dab tsi yog qee yam ntawm cov nroj tsuag uas peb yuav siv tau rau cov ntaub so ntswg?
Kev coj noj coj ua ntawm cov ntaub so ntswg cuam tshuam nrog kev siv cov khoom me me ntawm cov ntaub so ntswg (explants) uas yog kab lis kev cai nyob rau hauv ib qho nruab nrab as-ham nyob rau hauv sterile tej yam kev mob. Cauliflower, rose cuttings, African violet nplooj thiab carnation stems yuav tag nrho cov yooj yim tsim clones (tswj genetic luam) los ntawm cov ntaub so ntswg kab lis kev cai
