Qhov sib txawv tseem ceeb ntawm budding thiab gemmule tsim yog tias budding yog ib qho kev yug me nyuam asexual uas lub paj loj hlob sab nraud ntawm tus niam txiv, thaum lub sij hawm tsim gemmule yog ib txoj kev yug me nyuam asexual uas buds lossis gemmules tsim sab hauv. niam txiv lub cev.
Kev tawg yog ib hom kev yug me nyuam. Buds tuaj yeem txhim kho sab hauv lossis sab nraud niam txiv lub cev. Bud tsim tshwm sim los ntawm mitotic cell division. Li no, nws tsim cov noob caj noob ces zoo ib yam li leej niam. Thaum buds tsim nyob rau hauv cov kab mob 'lub cev, peb hu nws internal budding los yog endogenous budding los yog gemmule tsim. Internal buds yog hu ua gemmules thiab cov gemmule tsim no feem ntau pom nyob rau hauv daim txhuam cev zoo li Spongilia.
Nyob yog dab tsi?
Npaj yog ib hom kev yug me nyuam tsis zoo uas pom los ntawm qee yam kab mob. Nyob rau hauv cov txheej txheem no, ib tug tshiab kab mob tshwm sim raws li ib daim ntawv ntawm ib tug outgrowth los yog ib tug bud nyob rau saum npoo ntawm niam cell. Nws loj hlob sab nraud ntawm niam txiv. Yog li ntawd, nws tseem hu ua exogenous budding. Qhov tseeb, qhov no yog daim ntawv niaj hnub ntawm budding. Cov kab mob tshiab no loj tuaj thaum txuas nrog niam cell. Thaum nws hlob tiav lawm, nws cais tawm ntawm niam txiv thiab ua neej nyob ywj pheej.
Daim duab 01: Budding
Npaj yog pom muaj nyob rau hauv hydra, obelia, scypha thiab poov xab. Hydra siv cov cell regenerative rau budding. Vim yog qhov rov ua dua mitotic cell faib ntawm ib qhov chaw tshwj xeeb, buds tsim sab nraud ntawm lub cev hydra raws li cov neeg me. Thaum lawv paub tab txaus, lawv cais los ntawm niam txiv hydra thiab ua ywj siab hydra. Budding yog hom kev loj hlob tshaj plaws hauv cov poov xab. Cov poov xab yog unicellular. Ib lub xovtooj me me ua rau ntawm niam txiv poov xab cell. Niam txiv sib cais thiab ua ib tug ntxhais nucleus kom xa mus rau tus ntxhais cell.
Gemmule Formation yog dab tsi?
Gemmule tsim yog lwm txoj hauv kev ntawm kev yug me nyuam asexual. Gemmule tsim los kuj yog hu ua internal budding los yog endogenous budding. Hauv kev tsim cov gemmule, cov kab mob tshiab lossis cov kab mob loj hlob hauv niam cov kab mob. Yog li ntawd, gemmules los yog buds tsim nyob rau hauv niam txiv. Hom budding sab hauv no pom nyob rau hauv daim txhuam cev uas yog phylum Porifera. Spongilla yog ib tug genus ntawm daim txhuam cev uas qhia pom kev tsim gemmule. Nyob rau hauv niam spongllia, ob peb gemmules tsim, thiab lawv paub tab nyob rau hauv. Tom qab ntawd lawv tawm ntawm lub hauv paus kab noj hniav los ntawm kev qhib thiab dhau los ua neeg ywj pheej. Txhua lub gemmule muaj peev xwm los ua ib tus neeg tshiab.
Daim duab 02: Gemmule Formation
Gemmules muaj lub npog tiv thaiv. Yog li ntawd, gemmules tso cai rau cov sponges kom ciaj sia nyob rau hauv ib puag ncig tsis zoo. Gemmules tuaj yeem tiv taus desiccation lossis khov. Yog li, gemmules tuaj yeem suav tias yog dormant daim txhuam cev. Thaum cov xwm txheej yog qhov zoo, gemmules rov pib loj hlob mus rau hauv daim txhuam cev tag nrho. Cov kab mob endospores yog qhov sib piv rau gemmules ntawm daim txhuam cev.
Dab tsi yog qhov zoo sib xws ntawm Budding thiab Gemmule tsim?
- Nyob thiab gemmule tsim yog ob hom asexual reproduction txoj kev.
- Niam txiv thiab cov xeeb ntxwv yog caj ces zoo tib yam hauv ob txoj hauv kev.
- Buds lossis gemmule tsim tshwm sim vim mitosis.
Dab tsi yog qhov txawv ntawm Budding thiab Gemmule Formation?
Budding yog hom kev yug me nyuam uas tsis muaj menyuam uas tsim cov paj tshiab sab nraum niam txiv, thaum tsim cov gemmule yog hom kev yug menyuam tsis zoo uas cov gemmules lossis buds loj hlob hauv niam txiv lub cev. Yog li ntawd, buds loj hlob sab nraud thaum gemmules tsim sab hauv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm budding thiab gemmule tsim. Ntxiv mus, tsis zoo li buds, gemmules muaj ib tug resistant npog los ua raws li dormant qauv thaum lub sij hawm tsis zoo ib puag ncig.
Cov hauv qab no infographic teev qhov sib txawv ntawm budding thiab gemmule tsim nyob rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Budding vs Gemmule Formation
Cov buds tshiab tsim tawm sab nraud ntawm lub cev ntawm cov niam txiv nyob rau hauv budding, uas yog ib tug asexual txoj kev loj hlob nyob rau hauv cov poov xab, hydra thiab scypha. Gemmule tsim, tseem hu ua internal budding, muaj kev tsim ntawm ib pawg ntawm cov hlwb los yog gemmules nyob rau hauv niam txiv kab mob. Gemmule tsim yog ib tug yam ntxwv feature ntawm daim txhuam cev. Qhov sib txawv tseem ceeb ntawm budding thiab gemmule tsim yog tias buds tsim sab nraud thaum gemmules tsim sab hauv.
