Nyob zoo li protists yog cov neeg siv khoom ib leeg. Tsiaj-zoo li protists tseem hu ua Protozoa. Ib txhia kuj yog kab mob. Protozoa feem ntau muab faib ua 4 phyla: Amoebalike protists, flagellates, ciliates, thiab spore-forming protists.
Yuav ua li cas yog 4 txoj hauv kev uas cov tsiaj zoo li protists cais lawv li cas?
Muaj plaub yam tseem ceeb ntawm protozoans, cais raws li lawv txav mus los thiab lawv nyob qhov twg:
- Rhizopoda (tsiaj zoo li protists nrog "tus taw cuav" hu ua pseudopodia)
- Ciliates (protists npog hauv cov plaub hau me me zoo li cilia)
- Flagellates (protists nrog nplawm "tails")
- Sporozoa (parasitic protists)
Puas yog protists cais ua tsiaj?
"Lub ntsiab lus yooj yim tshaj plaws yog cov protists yog tag nrho cov kab mob eukaryotic uas tsis yog tsiaj txhu, nroj tsuag lossis fungi," said Alastair Simpson, tus xibfwb hauv chav haujlwm ntawm biology ntawm Dalhousie University.
3 hom tsiaj zoo li protists yog dab tsi?
Tsiaj-zoo li protists suav nrog flagellates, ciliates, thiab sporozoans.
Protozoans cais li cas?
Txhua hom kab mob protozoal raug xa mus rau kingdom Protista hauv Whittaker kev faib tawm. Cov protozoa tom qab ntawd muab tso rau hauv ntau pawg feem ntau raws li lawv txav mus los. Cov pab pawg hu ua phyla (singular, phylum) los ntawm qee tusmicrobiologists, thiab chav kawm los ntawm lwm tus.
