Kev zom zaub mov tshwm sim thaum cov khoom noj vacuole isfused nrog ib tug thib ob vacuole , hu ua lysosome, uas muaj lub zog digestive enzymes. Cov zaub mov yog degraded, nws cov as-ham yog absorbed los ntawm lub cell thiab nws cov khoom pov tseg nyob rau hauv lub digestive vacuole , uas tej zaum yuav tawm ntawm lub cell byexocytosis.
Ntawm no, dab tsi yog vacuole ua los ntawm?
A vacuole yog ib tug membrane-bound organelle. Vacuoles yog kaw lub hnab, ua ntawm daim nyias nyias los yog cov organic molecules hauv, xws li enzymes. Lawv tsis muaj cov duab lossis qhov loj me, thiab lub xovtooj ntawm tes tuaj yeem hloov pauv raws li nws xav tau. Lawv nyob hauv cov hlwb eukaryotic feem ntau thiab ua ntau yam. Lawv khaws tau pov tseg.
Ib tug kuj yuav nug, yuav ua li cas yog tias lub vacuole zaub mov puas lawm? Lub xovtooj ntawm tes yuav tsis muaj sijhawm los kho qhov kev puas tsuaj vim nws tsis tuaj yeem rhuav tshem cov molecules nyuaj thiab hloov mus rau qhov xav tau. Ntxiv mus, lub xovtooj ntawm tes yuav " tshaib plab" vim nws yuav tsis tuaj yeem khaws tag nrho cov as-ham kom raug. Qhov xaus: Ib tsob ntoo cell yuav tuag yam tsis muaj ib vacuole.
Hais txog qhov no, dab tsi yog cov ntaub ntawv khaws cia hauv vacuoles?
Vacuoles yog cov npuas cia nyob hauv cov hlwb. Lawv pom muaj nyob rau hauv ob qho tib si tsiaj thiab cov nroj tsuag hlwb tab sis muaj ntau ntau inplant cells. Vacuoles muaj peev xwm khw zaub mov los yog ntau yam khoom noj ntawm tes yuav xav tau kom muaj sia nyob. Lawv muaj peev xwm txawm khw cov khoom pov tseg kom cov seem ntawm tes tiv thaiv los ntawm kev sib kis.
Puas yog khoom noj vacuole yog organelle?
Khoom noj khoom haus vacuoles tsuas yog pom nyob rau hauv qee lub hlwb ntawm cov nroj tsuag, protists, fungi, thiab tsiaj txhu. Khoom noj khoom haus vacuoles Qhov tseem ceeb yog ib feem ntawm cov plasma membrane uas ncig zaub mov particles thaum lawv nkag mus rau hauv lub cell.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Lub ntiaj teb yuav hloov li cas yog tias cov nyhuv tsev cog khoom tsis muaj nyob rau hauv tag nrho cov lus nug?
A) Yog tsis muaj cov nyhuv tsev cog khoom, lub ntiaj teb yuav tawg tag nrho nws cov cua sov rau hauv qhov chaw. b) Txhua lub hnub ci hluav taws xob tuaj yeem nqus tau yam tsis muaj lub tsev cog khoom. C) Qhov tshwm sim ntawm tsis muaj cov nyhuv tsev cog khoom yuav yog lub ntiaj teb kub heev uas yeej tsis txias
Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Yuav ua li cas yog ib co qauv nyob rau hauv landforms nyob rau hauv lub ntiaj teb no?
Cov txheej txheem ntawm lub cev no ua rau cov roob, tiaj, toj, thiab toj siab, plaub hom av loj. Phaj tectonics tuaj yeem tsim cov roob thiab toj roob hauv pes thaum yaig tuaj yeem hnav cov av los tsim cov hav thiab hav zoov
