Qhov Tseem Ceeb Qhov txawv - Khoom noj Vacuole vs Contractile Vacuole
Protozoa yog ib leeg-celled eukaryotic kab mob. Lawv suav nrog ntau hom tsiaj xws li Euglena, Paramecium, Amoeba thiab lwm yam. Lawv muaj dav nyob rau hauv cov dej ib puag ncig thiab ua ntau yam haujlwm ntawm ib puag ncig biology thiab marine biology. Protozoa, ua eukaryotic yog tsim los ntawm cov organelles sib txawv, tawm ntawm cov vacuoles ua lub luag haujlwm tseem ceeb hauv lawv txoj sia. Vacuoles ntawm protozoa los yog feem ntau, vacuoles hauv microbes tuaj yeem muab faib ua ob hom loj xws li cov khoom noj vacuole thiab cov vacuole contractile. Khoom noj khoom haus vacuoles hauv protozoa yog vacuoles nrog lub plab zom mov. Cov zaub mov vacuoles fuse nrog lysosomes koom nrog hauv kev zom zaub mov. Contractile vacuoles hauv protozoa ua haujlwm hauv osmoregulation ntawm ib leeg-celled protozoa. Lawv koom nrog hauv kev tswj hwm osmotic siab hauv lub cell. Qhov sib txawv tseem ceeb ntawm cov khoom noj vacuoles thiab cov vacuoles contractile yog nyob ntawm nws txoj haujlwm. Cov zaub mov vacuoles koom nrog hauv kev zom zaub mov whereas contractile vacuoles koom nrog osmoregulation.
Khoom noj khoom haus Vacuole yog dab tsi?
Khoom noj khoom haus vacuoles yog cov hnab me me uas tau muab faib rau hauv lub cell cytoplasm ntawm protists, nroj tsuag, fungi thiab qee yam tsiaj. Lawv yog cov tseem ceeb organelles koom nrog ua kom tiav cov haujlwm ntawm kev zom zaub mov ua ke nrog lysosomes. Cov zaub mov vacuoles yog cov kab mob sib txuas nrog cov kab mob thiab tsim cov khoom noj vacuoles thaum cov zaub mov thiab cov cell nyob ze.
Cov cell membrane ntawm cov protists muaj peev xwm paub txog cov khoom noj. Thaum lawv paub txog cov khoom noj, lawv raug coj mus rau hauv lub cell ntawm endocytosis. Lub cell membrane yog invaginated inwards thaum cov zaub mov nyob rau hauv kev sib cuag nrog lub cell membrane thiab lawv tsim ib lub hnab zoo li qauv. Thaum cov khoom noj khoom haus nkag mus rau hauv lub hnab, lub plasma membrane yog pinched los ua ib lub vacuole los yog lub vesicle uas yog hu ua 'zaub mov vacuole'.
Daim duab 01: Khoom noj khoom haus Vacuoles hauv Paramecium
Khoom noj khoom haus vacuoles feem ntau yog oval nyob rau hauv cov duab thiab muab faib thoob plaws hauv lub cytoplasm. Cov zaub mov vacuoles tau muab faib ua ze ze rau lysosomes vim lawv ua haujlwm zoo hauv kev txhawb nqa txoj kev zom zaub mov. Lysosomes yog membranous organelles tsim ntawm digestive, hydrolytic enzymes uas muaj xws li m altases, sucrases, lipases, thiab nucleases. Cov enzymes no koom nrog hauv kev zom cov macromolecules. Thaum tsim cov khoom noj vacuole, cov zaub mov vacuole yog txuam nrog lysosome thiab ua ke lawv ua cov txheej txheem ntawm kev zom zaub mov. Cov lysosomes ntxeem cov zaub mov vacuoles ntawm phagocytosis kom zom cov ntsiab lus nqa. Cov khoom digested ces tso tawm mus rau lub cytoplasm qhov chaw uas lawv koom nrog ua lawv txoj haujlwm lom neeg
Kev cog lus Vacuole yog dab tsi?
Cov vacuoles muaj nyob rau hauv cov dej protozoa feem ntau. Lawv koom nrog hauv osmoregulation hauv cell. Lawv koom nrog hauv kev tshem tawm cov dej ntawm lub cell los ntawm cov txheej txheem osmosis. Lub mechanism ntawm kev txiav txim ntawm contractile vacuole tuaj yeem piav qhia hauv cov txheej txheem osmoregulation ntawm Paramecium. Paramecium muaj ob lub tshuab nqus tsev vacuoles, qhov twg ib qho muab tso rau hauv qhov chaw sab hauv ntawm lub xov tooj ntawm tes thiab lwm qhov yog muab tso rau hauv qab ntawm lub cell.
Daim duab 02: Daim Ntawv Cog Lus Vacuoles ntawm Paramecium
Paramecium yog cov dej tshiab protozoan thiab yog li ntawd, nws ntsib teeb meem ntawm cov dej nkag mus rau ntawm tes. Kev nkag dej ntau dhau rau hauv lub cell tuaj yeem ua rau lub cell tawg. Txhawm rau tiv thaiv qhov no, cov vacuoles contractile, tam sim no nyob rau hauv lub cell cytoplasm daim ntawv cog lus thiab nthuav nyob rau hauv ib ntus kom thawb cov dej tawm ntawm lub cell. Lub contractile vacuoles coj cov dej ntau dhau mus rau endoplasmic reticulum uas tom qab ntawd coj cov dej ntau dhau ntawm cov nephridia.
Dab tsi zoo sib xws ntawm Food Vacuole thiab Contractile Vacuole?
- Ob leeg pom muaj nyob hauv protozoa.
- Ob leeg nyob hauv lub cell cytoplasm.
- Ob leeg yog cov kab mob membrane-bound organelles.

Summary – Food Vacuole vs Contractile Vacuole
Khoom noj khoom haus vacuoles thiab Contractile vacuoles muaj nyob rau hauv eukaryotic hlwb tshwj xeeb tshaj yog nyob rau hauv protozoa. Lawv txawv ntawm cov haujlwm uas lawv ua tab sis tseem ceeb heev rau kev muaj sia nyob ntawm lub cev. Cov zaub mov vacuoles koom nrog hauv kev zom zaub mov nrog rau lysosomes. Contractile vacuoles feem ntau koom nrog hauv kev tswj cov dej hauv cov xov tooj ntawm tes, yog li xyuas kom meej tias osmotic siab yog sib npaug hauv lub cell. Kev ua haujlwm kom zoo ntawm cov vacuoles contractile tiv thaiv lub xovtooj ntawm qhov tawg uas tshwm sim los ntawm kev nkag mus ntau dhau ntawm cov dej. Qhov no yog qhov txawv ntawm cov khoom noj vacuoles thiab contractile vacuoles.
