Nyob rau hauv biology, lub feem ntau txhais tau tias ntawm kev loj hlob hauv ib kab mob txawv ntawm kab mob rau kab mob . Piv txwv li, multicellular kab mob loj hlob ntawm cov txheej txheem ntawm cellular faib hu ua mitosis, thaum lwm tus (ua unicellular ) loj hlob los yog rov tsim dua colonyally-hais lus ntawm tus txheej txheem hu ua binary fission.
Xav txog qhov no, yuav ua li cas loj hlob nyob rau hauv multicellular kab mob?
Kev loj hlob yog muaj peev xwm ua neej nyob kab mob . Kev loj hlob txhais tau hais tias tau txais qhov loj me, thiab rau ntau lub cellular kab mob qhov no yog ua los ntawm kev ua ntau lub hlwb. Cov nroj tsuag muaj cov ntaub so ntswg tshwj xeeb hu ua meristems qhov twg kev loj hlob tshwm sim . Hauv paus apical meristems loj hlob mus rau hauv av, thiab tua apical meristems loj hlob tuaj.
Tsis tas li ntawd, cov kab mob unicellular teb li cas rau lawv ib puag ncig? Teb rau Environment Unicellular kab mob ua tsis muaj peev xwm no. Lawv yuav tsum paub lawv nyob ib ncig ntawm lwm txoj kev. Qee cov kab mob tuaj yeem kuaj cov tshuaj, xws li qab zib, hauv lawv ib puag ncig thiab txav mus rau lawv . Photosynthetic protists, zoo li Euglena, tuaj yeem ntes lub teeb siv cov sensors tshwj xeeb.
Cov kab mob unicellular tuaj yeem pom nyob qhov twg?
Cov kab mob Unicellular suav nrog cov kab mob, protists, thiab poov xab. Piv txwv li, paramecium yog ib qho khau khiab, unicellular kab mob pom hauv pas dej. Nws siv cov khoom noj los ntawm dej thiab zom nws hauv cov organelles hu ua zaub mov vacuoles.
Cov kab mob unicellular ua haujlwm li cas?
Ib lub cell ntawm a unicellular kab mob yuav tsum muaj peev xwm ua tag nrho cov muaj nuj nqi tsim nyog rau lub neej . Cov no muaj nuj nqi muaj xws li metabolism, homeostasis thiab kev loj hlob. Tshwj xeeb, cov tib lub hlwb yuav tsum thauj khoom, tau txais thiab siv lub zog, pov tseg cov khoom pov tseg, thiab tsis tu ncua teb rau lawv ib puag ncig.

Thaum cov kab mob ntsib qhov txwv tsis pub muaj hom kev loj hlob li cas lawv qhia?
Thaum cov kab mob ntsib qhov txwv tsis pub, lawv pom kev loj hlob (S-shaped nkhaus, nkhaus B: Daim duab hauv qab). Kev sib tw rau cov peev txheej xws li zaub mov thiab qhov chaw ua rau qhov kev loj hlob tsis tau nce ntxiv, yog li cov pej xeem theem tawm. Txoj kab ncaj nraim ntawm txoj kab kev loj hlob no yog lub peev xwm nqa tau
Lub luag hauj lwm ntawm cov nroj tsuag kev loj hlob regulators nyob rau hauv cov nroj tsuag kab lis kev cai yog dab tsi?
Hauv cov nroj tsuag kab lis kev cai, kev loj hlob regulator muaj lub luag haujlwm tseem ceeb xws li tswj cov hauv paus thiab tua kev loj hlob hauv cov nroj tsuag tsim thiab callus induction. Cytokinin thiab auxin yog ob txoj kev loj hlob zoo
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
Puas yog cov kab mob unicellular kab mob?
Tus Kab Mob Qhov Twg Zoo? Cov kab mob tsis raug cais raws li cov hlwb thiab yog li tsis yog unicellular lossis multicellular kab mob. Cov kab mob muaj cov genomeshat muaj xws li DNA lossis RNA, thiab muaj cov piv txwv ntawm cov kab mob uas yog ob leeg-stranded orsingle-stranded
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
