Qhov tseem ceeb, protozoa yog ib leeg-celled eukaryotes. Qhov no txhais tau tias lawv yog cov kab mob ib leeg nkaus xwb uas muaj cov nuclei ntxiv rau lwm tus tseem ceeb organelles nyob rau hauv cytoplasm thiab nyob ib ncig ntawm a daim nyias nyias . Lawv muaj nyob raws li cov kab mob muaj sia nyob dawb lossis zoo li cov cab.

Ntawm no, lub neej voj voog ntawm protozoa yog dab tsi?

Ib txhia cov protozoa muaj ob theem lub neej mus los , hloov pauv ntawm cov theem loj hlob (piv txwv li, trophozoites) thiab cov hlwv tsis tu ncua. Raws li cov hlwv, cov protozoa tuaj yeem muaj sia nyob rau qhov hnyav, xws li raug rau huab cua sov lossis tshuaj muaj teeb meem, lossis ntev mus yam tsis tau txais cov as -ham, dej, lossis oxygen rau lub sijhawm.

Ib yam nkaus, dab tsi yog protozoa hauv cov lus yooj yim? Protozoa yog me me (tab sis tsis yog yooj yim ) cov kab mob. Lawv yog tib leeg xwb -celled heterotrophic eukaryotes, uas noj cov kab mob thiab lwm yam khoom noj. Nws yog qhov yooj yim tuav-txhua lub sijhawm, tab sis qhov tseeb ' cov protozoa 'tau muab cais ua ntau tus phyla sib txawv.

Tom qab ntawd, tus protozoa rov tsim dua li cas?

Protozoa yug me nyuam los ntawm ob qho tib si asexual thiab kev sib deev txhais tau tias, txawm tias yog kev sib deev luam tawm tsawg dua thiab tshwm sim hauv qee pawg. Feem ntau protozoa yug me nyuam asexually los ntawm kev faib xov tooj ntawm tes tsim ob lub cell sib npaug lossis qee zaum tsis sib xws. Hauv qee qhov cov protozoa ntau fission lossis schizogamy paub tias tshwm sim.

Cov kev cais ntawm protozoa yog dab tsi?

Txhua hom kab mob protozoal tau muab rau nceeg vaj Protista hauv Whittaker kev faib tawm. Cov protozoa tom qab ntawd tau muab tso rau hauv ntau pab pawg feem ntau ntawm qhov lawv txav mus li cas. Cov pab pawg no raug hu ua phyla (ib yam, kab mob ) los ntawm qee tus microbiologists, thiab chav kawm los ntawm lwm tus.
