Qhov sib txawv tseem ceeb ntawm exogenous thiab endogenous budding yog hais tias nyob rau hauv exogenous budding, cov kab mob tshiab los yog lub bud tsim nyob rau saum npoo ntawm leej niam leej txiv thiab ces matures thiab detaches los ntawm nws thaum nyob rau hauv endogenous budding, lub cev tshiab los yog lub bud tsim nyob rau hauv niam cell.
Npaj yog ib hom kev yug me nyuam los ntawm cov xeeb ntxwv tshiab uas txuas nrog niam txiv. Nws tshwm sim los ntawm ib tug outgrowth los yog ib tug bud. Feem ntau, lub paj loj hlob ntawm niam txiv cell thiab txuas mus rau sab nraud. Tom qab ntawd nws matures thiab detaches los ntawm leej niam leej txiv, dhau los ua cov kab mob ywj pheej. Yog li, hom budding no hu ua exogenous budding. Tab sis, nyob rau hauv ib co kab mob, internal budding kuj pom. Ntawm no, ib tug bud los yog ib tug ntxhais cell yog tsim nyob rau hauv lub niam cell. Yog li ntawd, qhov no yog hu ua endogenous budding.
Dab tsi yog Exogenous Budding?
Exogenous budding yog ib hom kev yug me nyuam asexual pom los ntawm qee yam kab mob nyob. 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 yog hu ua exogenous budding. Qhov tseeb, qhov no yog daim ntawv ib txwm ntawm budding.
Daim duab 01: Exogenous Budding
Thaum txuas nrog niam cell, lub cev tshiab loj tuaj. Thaum nws dhau los ua tiav, nws cais tawm ntawm niam txiv thiab coj tus cwj pwm ywj pheej. Exogenous budding feem ntau pom nyob rau hauv hydra, obelia, scypha, thiab poov xab.
Dab tsi yog Endogenous Budding?
Endogenous budding yog lwm txoj kev ntawm kev yug menyuam. Nyob rau hauv endogenous budding, cov kab mob tshiab los yog buds tsim nyob rau hauv leej niam kab mob los yog cell. Ntawm no, lub bud loj hlob hauv niam txiv. Li no, nws yog hu ua endogenous budding.
Daim duab 02: Endogenous Budding
Piv txwv li, hom budding no pom nyob rau hauv daim txhuam cev uas yog phylum Porifera. Spongilla yog ib tug genus ntawm daim txhuam cev uas qhia tau hais tias endogenous budding. Nyob rau hauv niam spongllia, ob peb buds hu ua gemmules daim ntawv 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.
Dab tsi yog qhov zoo sib xws ntawm Exogenous thiab Endogenous Budding?
- Exogenous thiab endogenous budding yog ob hom budding pom nyob rau hauv cov kab mob nyob.
- Lawv yog hom kev tsim tawm ntawm kev sib deev.
- Tsis tas li ntawd, cov xeeb leej xeeb ntxwv los ntawm ob daim ntawv no zoo ib yam rau lawv niam thiab txiv.
- Tsis tas li, ob qho tib si tshwm sim los ntawm mitotic cell division.
Qhov txawv ntawm Exogenous thiab Endogenous Budding yog dab tsi?
Exogenous thiab endogenous budding yog ob hom budding uas yog asexual reproduction txoj kev. Lub buds tsim externally nyob rau saum npoo ntawm leej niam leej txiv nyob rau hauv exogenous budding. Nyob rau hauv sib piv, lub buds tsim internally nyob rau hauv lub niam niam txiv nyob rau hauv endogenous budding. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm exogenous thiab endogenous budding. Sab nraud budding yog ib lub ntsiab lus rau exogenous budding thaum internal budding yog ib tug synonym ntawm endogenous budding.
Hydra, Scypha thiab Obelia yog ob peb yam kab mob uas qhia txog exogenous budding thaum spongllia thiab lwm yam sponges yog piv txwv kab mob uas qhia endogenous budding.
Hauv qab infographic qhia txog qhov sib txawv ntawm exogenous thiab endogenous budding.
Summary – Exogenous vs Endogenous Budding
Kev tawg yog ib hom kev yug me nyuam. Buds tuaj yeem tshwm sim hauv lossis ntawm lub cev. Lawv tshwm sim los ntawm mitotic cell division. Yog li ntawd, cov xeeb ntxwv yog genetic zoo tib yam rau niam txiv. Yog hais tias lub budding tshwm sim nyob rau saum npoo ntawm niam cell, peb hu nws exogenous budding. Nyob rau hauv sib piv, yog hais tias lub budding tshwm sim nyob rau hauv lub niam niam txiv lub cev, peb hu nws endogenous budding. Qhov no yog qhov sib txawv tseem ceeb ntawm exogenous thiab endogenous budding. Hydra thiab poov xab qhia exogenous budding feem ntau thaum sponges qhia endogenous budding.
