Starch, ib daim ntawv khaws cov piam thaj, feem ntau pom nyob ib ncig ntawm pyrenoids.
Dab tsi yog khaws cia hauv pyrenoids?
Feem ntau ntawm cov tswvcuab muaj ib lossis ntau lub cev cia hu ua pyrenoids nyob hauv chloroplasts. Pyrenoids muaj protein ntxiv rau cov hmoov txhuv nplej siab. Qee cov algae yuav khaws cov zaub mov hauv daim ntawv ntawm cov roj tee. Yog li, lo lus teb raug yog Starch'.
Pyrenoids muab piv txwv li cas?
Pyrenoids muaj nyob rau hauv cov kab mob algal, tsis hais seb cov chloroplast tau txais los ntawm ib qho kev tshwm sim endosymbiotic (piv txwv li ntsuab thiab liab algae, tab sis tsis nyob hauv glaucophytes) lossis ntau yam kab mob endosymbiotic. (diatoms, dinoflagellates, coccolithophores, cryptophytes, chlorarachniophytes, thiab euglenozoa.
Pyrenoids spirogyra khw yog dab tsi?
Cov chloroplasts tsim cov kauv nyob ib ncig ntawm lub vacuole thiab muaj lub cev tshwj xeeb hu ua pyrenoids uas khaws starch. Cov phab ntsa ntawm tes muaj ib txheej txheej ntawm cellulose thiab txheej txheej ntawm pectin, uas yog lub luag haujlwm rau kev ntxhib los mos ntawm algae. Hom Spirogyra tuaj yeem tsim tawm ob qho tib si sib deev thiab asexually.
Puas yog spirogyra pyrenoids nyob rau?
Pyrenoids yog sub-cellular microcompartments uas pom nyob rau hauv cov chloroplasts ntawm ntau algae, zoo li Spirogyra thiab hauv ib pawg ntawm cov nroj tsuag hauv av, hornworts. Hauv cov algae no, pyrenoids tej zaum ua haujlwm los kho cov pa roj carbon. Hauv lwm cov algae, pyrenoids yog qhov chawntawm carbohydrate (feem ntau starch) cia.

Qhov twg hauv qab no yog tsim los ntawm pyrenoids?
Cov pyrenoid, cov qauv ntom ntom sab hauv lossis ib sab ntawm chloroplasts ntawm qee cov algae, muaj ntau ntawm ribulose biphosphate carboxylase, ib qho ntawm cov enzymes tsim nyog hauv photosynthesis rau carbon fixation thiab yog li qab zib tsim.
