Hnub no peb yuav pom tias kab noj hniav uas muaj cell sap yog dab tsi. Ntawd yog, peb yuav xav txog kev teem caij ntawm vacuoles hauv lub cev. Raws li koj paub, lub xovtooj ntawm tes yog ib chav tsev tsim qauv ntawm txhua yam uas nyob ib puag ncig peb. Tab sis nws muaj ntau cov organelles. Ib tug ntawm lawv zoo li kab noj hniav uas muaj cov kua cell thiab hu ua vacuole.
Lub luag haujlwm ntawm lub cev no muaj ntau haiv neeg, peb yuav tsum tau mloog lub ntsiab lus no. Thiab tam sim no nws yog ib qho tsim nyog kom nkag siab tias lub xov tooj ntawm tes, ua tsaug rau nws cov organelles, muaj peev xwm ua kom muaj kev ywj pheej. Cov me me tshaj plaws no tsis tas yuav muab tso rau hauv ib qho kev sib xyaw ua ke. Nws muaj ntau yam khoom uas tso cai rau nws nyob ntawm nws tus kheej. Tam sim no cia peb mus rau qhov kev txiav txim siab ntawm ib qho ntawm cov khoom uas ua lub luag haujlwm tseem ceeb hauv lub neej ntawm tes.
Vacuole
Yog li no, peb twb tau hais tias kab noj hniav uas muaj cell sap muaj npevacuole. Qhov no organoid yog sau nrog ib tug aqueous tov ntawm ntau yam tshuaj, uas peb yuav nrhiav tau ob qho tib si organic thiab inorganic. Yuav tsum muaj kev koom tes los tsim vacuoles:
- EPS.
- Golgi Apparatus.
Cia peb pib nrog qhov tseeb tias txhua lub cell cog muaj cov kab mob no, tsuas yog cov menyuam yaus muaj ntau ntau ntawm lawv. Vim li cas qhov no tshwm sim? Raws li qhov tshwm sim ntawm kev loj hlob, lawv sib koom ua ke, uas ua rau tsim lub hauv paus vacuole. Nws tseem yog ib qho tseem ceeb heev uas yuav tsum nco ntsoov tias cov nroj tsuag paub tab yuav luag tag nrog cov vacuole no (ntau dua 90 feem pua). Nyob rau tib lub sijhawm, tag nrho lwm cov organelles thiab cell nucleus txav mus rau lub plhaub.
Lub vacuole txwv rau tonoplast, qhov no yog lub npe ntawm daim nyias nyias ntawm cov nroj tsuag cell organoid. Cov kua dej uas nyob hauv lub vacuole yog cell sap.
Yog li, cov kab noj hniav uas muaj cov kua qaub ntawm tes thiab ntsuas ntau dua 90 feem pua ntawm cov kab noj hniav ntawm tag nrho cov cell yog lub hauv paus vacuole. Cov kua txiv hmab txiv ntoo no suav nrog ntau cov tshuaj, ntawm cov uas:
- ntsev;
- monosaccharides;
- glycosides;
- alkaloids;
- anthocyanins thiab lwm yam.
Ydisaccharides;
Yamino acids;
Functions
Cov kab mob ntawm tes uas muaj cov kua qaub ntawm tes yog hu ua vacuole. Nws ua haujlwm ntau yam sib txawv. Tam sim no peb tab tom xav txog lawv. Yuav pib nrog, peb yuav muab rau koj nrog lawv hauv daim ntawv teev npe:
- nqus dej. Dej yog qhov tseem ceeb rau cov nroj tsuag thiab kev saib xyuas cov nroj tsuag lub neej. Tsis tas li ntawd, H2O molecules yog qhov tseem ceeb rau cov nroj tsuag photosynthesis.
- Cov nroj tsuag xim. Qhov no tuaj yeem ua tau vim muaj cov tshuaj anthocyanin. Lawv muaj peev xwm los xim cov kab mob hauv nruab nrog cev (txiv hmab txiv ntoo, paj, nplooj).
- Tshem tawm cov tshuaj lom. Oxalate crystals muab tso rau hauv vacuoles. Qee cov metabolites theem nrab kuj muaj qhov zoo (pab tau) zoo, piv txwv li, lawv muab cov nroj tsuag iab saj thiab txuag lawv ntawm kev noj.
- Cov khoom noj khoom haus. Lub xovtooj tuaj yeem, yog tias tsim nyog, siv cov khoom khaws cia ntawm lub vacuole, vim nws khaws ntau yam khoom muaj txiaj ntsig rau lub cell.
- Txhob muab cov qub qub ntawm tes los ntawm kev tsim cov kua mis nyuj.
Vacuoles hauv tsiaj hlwb
Peb twb tau hais tias cov kab noj hniav hauv cytoplasm uas muaj cov kua qaub ntawm tes yog vacuole. Tab sis mus txog rau ntu no, tsuas yog cov nroj tsuag cog tau tham. Tam sim no peb yuav tau paub txog lub luag haujlwm ntawm cov kab mob no hauv cov tsiaj.
Vacuoles muaj nyob rau hauv feem ntau protozoa. Yog li, piv txwv li, pulsating sawv daws pom muaj nyob rau hauv dej tshiab thiab pab rau osmotic kev cai. Qee cov vertebrates multicellular thiab unicellular kab mob muaj cov plab hnyuv vacuoles uas muaj ntau cov enzymes sib txawv. Nws tseem ceeb heev kom paub tias nyob rau hauv cov tsiaj siab dua cov organelles yog tsim nyob rau hauv phagocytes.
Qhov txawv ntawm cov nroj tsuag thiab tsiaj txhu
Peb twb hais lawmorganelles, uas yog cov kab noj hniav uas muaj cov kua qaub, muaj nyob rau hauv cov nroj tsuag thiab tsiaj txhu. Lawv txawv li cas? Nws yog ib qho tseem ceeb kom nkag siab tias nyob rau hauv lub cell lawv tsis yog nyob rau hauv tus nqi xwb. Hauv cov nroj tsuag, lawv nyob 95 feem pua, thiab hauv cov tsiaj - tsuas yog 5 feem pua.
