Protozoa nyob hauv dej tshiab raug rau ib puag ncig hypotonic. Cov dej ntws hla lawv cov plasma membrane vim lawv cov cytosol ib txwm hypertonic rau ib puag ncig. Ntau cov phab ntsa-tsawg protozoa muaj cov organelle, lub contractile vacuole complex (CVC), uas sau thiab expels dej ntau dhau.

Vim li cas cov protozoans xav tau cov vacuoles contractile?

Contractile vacuole, regulatory organelle, feem ntau yog kheej kheej, pom nyob rau hauv dej tshiab protozoa thiab qis metazoans, xws li daim txhuam cev thiab hydras, uas khaws cov dej ntau dhau ntawm cov protoplasm thiab ntuav nws mus rau hauv nruab nrab ib puag ncig. Nws kuj tseem tuaj yeem tshem tawm cov khoom pov tseg nitrogenous.

Qhov twg protozoan muaj contractile vacuole?

Qhov kev nkag siab zoo tshaj plaws ntawm cov vacuoles yog cov protists Paramecium, Amoeba, Dictyostelium thiab Trypanosoma, thiab tsawg dua qhov ntsuab alga Chlamydomonas.

Nyob rau hauv uas protozoans contractile vacuoles tsis tuaj?

Cov vacuoles thiab cov khoom noj vacuoles tsis tuaj nyob hauv chav kawm-Sporozoa ntawm phylum-Protozoa xws li, Trypanosoma sp. (pw tsaug zog kab mob ua rau kab mob).

Lub contractile vacuole pab hauv protozoa ua pa li cas?

Lub ntsiab lus ntawm lub tshuab nqus tsev vacuole yog txhawm rau tso dej tawm ntawm lub xovtooj los ntawm cov txheej txheem hu ua osmoregulation, kev tswj ntawm osmotic siab. Nws tshwm sim hauv cov dej tsis qab ntsev, tab sis feem ntau hauv lub nceeg vaj Protista tag nrho.
