Ib amoeba (/?ˈmiːb?/; tsis tshua sau amœba; plural am(o)ebas lossis am(o)ebae /?ˈmiːbi/), feem ntau hu ua amoeboid, yog hom cell los yog unicellular kab mob uas muaj peev xwm hloov nws cov duab, feem ntau los ntawm kev ncua thiab thim rov qab pseudopods.
Kuj paub, dab tsi yog ib lub cell amoeba?
Ib Amoeba . Ib amoeba , tej zaum sau li " ameba ua ", yog ib lo lus feem ntau siv los piav txog a ib leeg Cov kab mob eukaryotic uas tsis muaj cov duab meej thiab uas txav los ntawm pseudopodia. Pseudopodia los yog pseudopods yog ib ntus projections ntawm tus cell thiab lo lus literally txhais tau tias "foot cuav".
Tsis tas li ntawd, dab tsi yog lub npe ntawm ib lub cev ntawm tes? Ib leeg - celled kab mob yog hu ua unicellular kab mob . 'Uni-' txhais tau tias ' ib , 'yog li npe 'unicellular' txhais tau tias ' ib cell . ' Ib qho piv txwv ntawm unicellular kab mob yuav yog qee hom algae xws li Euglena, ntsuab algae, thiab lwm yam prokaryotic kab mob xws li cov kab mob feem ntau.
Kuj nug, puas yog amoeba ib yam kab mob unicellular?
Ib txhia nyob kab mob yog tsim los ntawm ib zaug xwb cell, cov no yog hu ua unicellular . Cov no kab mob muaj thaj tsam loj rau qhov ntim qhov sib piv thiab tso siab rau qhov yooj yim diffusion kom tau raws li lawv cov kev xav tau. Ib qho piv txwv ntawm a unicellular tsiaj yog Amoeba . Amoeba noj me me kab mob xws li kab mob.
Puas yog Amoeba yog thawj lub cev muaj sia nyob?
Ib leeg xwb amoeb ua ib thaum ntxov daim ntawv ntawm lub neej nyob rau hauv lub ntiaj teb uas evolved nyob rau hauv lub hiav txwv. Tam sim no cov kws tshawb fawb tau nthuav tawm cov ntxov tshaj plaws puas tau terrestrial hom ntawm ib yam tseem ceeb hu ua testate amoeb.

Dab tsi yog thawj kauj ruam ntawm kev tsim ib qho perpendicular los ntawm ib qho taw tes mus rau kab?
Txuas tus taw tes rau qhov taw tes uas cov arcs sib tshuam. Siv ib tug straightedge los xyuas kom meej cov kab yog ncaj. Txoj kab koj kos yog perpendicular rau thawj kab, los ntawm qhov muab taw tes rau ntawm kab
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Cov kab mob puas yog ib hom kab mob ntawm tes?
Teb thiab piav qhia: Cov kab mob no tsis suav tias yog cov cell nyob thiab yog li ntawd tsis yog ib leeg-celled lossis ntau-celled. Lawv tsuas yog suav hais tias yog cov plhaub protein
Puas yog ib qho kab mob ntawm tes yog ib yam muaj sia nyob?
Cov kab mob (singular: kab mob) yog ib pawg loj ntawm cov kab mob nyob. Feem ntau yog cov microscopic thiab unicellular, nrog cov qauv ntawm tes yooj yim uas tsis muaj cell nucleus, thiab cov organelles xws li mitochondria thiab chloroplasts. Cov kab mob muaj ntau tshaj plaws ntawm tag nrho cov kab mob
