Qhov sib txawv tseem ceeb ntawm protoplast thiab heterokaryon yog tias cov protoplast yog cov phab ntsa-tsawg cog cell thaum heterokaryon yog lub xovtooj ntawm tes uas muaj ob lossis ntau dua nuclei ntawm cov hauv paus chiv keeb los yog ntau lub xeev hauv ib qho cytoplasm.
Protoplast thiab heterokaryon yog ob hom cell sib txawv uas muaj txiaj ntsig zoo hauv kev tshawb fawb ntawm cov kab lis kev cai cog qoob loo thiab cell biology raws li. Protoplast yog cov nroj tsuag cell. Tab sis nws tsis muaj lub cell phab ntsa vim nws tau raug tshem tawm enzymatically los yog mechanically. Ntawm qhov tod tes, heterokaryon yog ib lub cell multinucleated. Nws muaj ob lossis ntau qhov sib txawv nuclei.
YProtoplast yog dab tsi?
Protoplast yog cov nroj tsuag uas tsis muaj phab ntsa ntawm tes. Peb tuaj yeem tsim cov hlwb no los ntawm kev tsim cov plasmolyzation ntawm cov hlwb. Thaum lawv tau ua lawm, lawv ua tsis yooj yim heev. Nws yog vim tsis muaj cov phab ntsa ntawm tes. Txhawm rau cais cov protoplasts, nws yog ib qho tsim nyog yuav tsum ua raws li cov txheej txheem kev siv tshuab lossis cov txheej txheem enzymatic. Hauv kev sib piv rau kev sib cais ntawm cov neeg kho tshuab, kev sib cais enzymatic muaj kev nyab xeeb, thiab nws tshem tawm cov phab ntsa ntawm tes tsis ua rau cov protoplast puas.
Daim duab 01: Protoplasts
Tsis tas li ntawd, qhov tsis txaus ntseeg txawv ntawm cov protoplasts nyob ntawm qhov loj hlob ntawm cov nroj tsuag, lub caij ntawm lub xyoo, lub sijhawm ntawm hnub thiab hnub nyoog ntawm cov nroj tsuag uas tau xaiv. Tom qab cais cov protoplasts, lawv tuaj yeem raug coj mus rau hauv cov nroj tsuag, thiab thaum kawg, tuaj yeem hloov mus rau hauv cov nroj tsuag tshiab. Li no, protoplasts yog siv los tsim cov noob caj noob ces hloov lossis hloov cov nroj tsuag.
Heterokaryon yog dab tsi?
Heterokaryon yog ib lub xovtooj ntawm tes uas muaj ob lossis ntau lub nuclei ntawm txawv keeb kwm hauv ib lub cytoplasm. Cov hlwb no tshwm sim vim kev sib txuas ntawm ob lub hlwb sib txawv. Li no thiaj li yuav ua rau heterokaryon, ob lub hlwb yuav tsum los ze zog thiab sib cuag. Thaum lawv sib cuag, lawv cov plasma daim nyias nyias fuse ib leeg thiab hloov mus rau hauv ib lub cell uas muaj ib qho cytoplasm. Thaum kawg, lub cytoplasm no muaj ob qho tib si pub nuclei.
Daim duab 02: Heterokaryon
Heterokaryon tsim feem ntau pom nyob rau hauv cov kab mob thaum lub sij hawm kev sib deev. Yeej, nws muab kev hloov pauv caj ces rau mycelium. Txawm hais tias heterokaryons yog cov hlwb txawv txav, lawv qhov kev tsom xam yog qhov tseem ceeb los txiav txim siab txog kev sib cuam tshuam ntawm nuclear-cytoplasmic thiab kawm txog kev cuam tshuam ntawm cytoplasmic yam ntawm cov noob caj noob ces.
Dab tsi yog qhov zoo sib xws ntawm Protoplast thiab Heterokaryon?
- Protoplast thiab heterokaryon yog cov hlwb.
- Ob leeg tseem ceeb hauv ntau qhov chaw kawm.
- Tshwj xeeb, ob leeg yog siv los tsim cov noob caj noob ces.
Qhov txawv ntawm Protoplast thiab Heterokaryon yog dab tsi?
Protoplast thiab heterokaryon yog ob hom hlwb. Protoplast tsis muaj cov phab ntsa ntawm tes. Nws tuaj yeem yog phab ntsa-tsawg cog cell lossis kab mob fungal lossis kab mob ntawm tes. Thaum lub cell phab ntsa tshem tawm, protoplast yuav tawg yooj yim dua. Ntawm qhov tod tes, heterokaryon yog ib lub xovtooj ntawm tes, tshwj xeeb tshaj yog cov kab mob fungal uas muaj ob lossis ntau qhov sib txawv ntawm cov nuclei. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm protoplast thiab heterokaryon.
Ntxiv mus, peb tuaj yeem tsim cov protoplasts los ntawm kev tsim cov plasmolyzation ntawm cov nroj tsuag. Whereas, heterokaryon yog ib qho tshwj xeeb ntawm tes uas tshwm sim thaum lub sij hawm kev sib deev ntawm cov fungi. Yog li, peb tuaj yeem xav txog qhov no kuj yog qhov sib txawv ntawm protoplast thiab heterokaryon. Tsis tas li ntawd, raws li qhov tseem ceeb ib yam nkaus, peb tuaj yeem pom qhov sib txawv ntawm protoplast thiab heterokaryon. Qhov ntawd yog; Kev siv cov protoplast yog tsim los hloov cov noob caj noob ces, cog cov ntaub so ntswg kab lis kev cai, thiab nyob rau hauv kev tsom xam ntawm membrane bioogy thaum, ib tug siv ntawm heterokaryon yog nyob rau hauv kev sib deev reproduction ntawm fungi.
Summary – Protoplast vs Heterokaryon
Protoplast feem ntau yog cov nroj tsuag tsis muaj phab ntsa ntawm tes. Siv cov txheej txheem enzymatic degradation lossis mechanical method, cov phab ntsa ntawm tes ntawm tes raug tshem tawm yam tsis muaj kev puas tsuaj rau sab hauv ntawm tes. Tsis tas li ntawd, protoplast kuj hais txog cov kab mob fungal lossis kab mob uas tsis muaj phab ntsa ntawm tes. Ntawm qhov tod tes, heterokaryon yog lub xovtooj ntawm tes uas muaj ob lossis ntau lub nuclei hauv ib qho cytoplasm. Yog li, qhov no yog qhov txawv ntawm protoplast thiab heterokaryon.
