Raws li ib tug unicellular protozoa, Stentor tuaj yeem ncav cuag 2 millimeters loj, ua rau lawv pom ntawm qhov muag liab qab. Lawv nyob hauv ib puag ncig dej tsis khov thiab noj cov kab mob. Lawv txav thiab noj los ntawm kev siv cilia, thiab lawv tswj hwm lawv cov dej sib npaug nrog kev siv lub tshuab nqus tsev vacuole.
Xav txog qhov no, yog Stentor unicellular lossis multicellular?
Taw qhia. Stentors yog a unicellular ciliate, sau tseg rau lawv trumpet zoo li lub cev (li no lub npe tus stentor , tom qab Greek herald ntawm Trojan tsov rog). Stentors yog ib qho loj tshaj plaws ib leeg kab mob, qee zaus ua ob peb millimeters ntev.
Ib yam li ntawd, lub nceeg vaj twg Stentor koom nrog? Kuj tseem hu ua "trumpet animalcule," Stentor belongs rau chav kawm Spirotrichea hauv phylum Ciliophora . Lawv yog qee qhov loj tshaj plaws protozoans paub thiab qee hom tuaj yeem ncav cuag ob millimeters (0.08 nti) ntev.
Yog li ntawd, Stentor puas yog prokaryote?

Puas yog Stentor autotrophic lossis heterotrophic?
Stentor yog omnivorous heterotrophs . Feem ntau, lawv noj cov kab mob los yog lwm yam protozoans. Vim lawv qhov loj me, lawv kuj muaj peev xwm noj tau qee yam ntawm cov kab mob me me, xws li rotifers. Stentor feem ntau reproduces asexually los ntawm binary fission.
