Qhov Tseem Ceeb Qhov txawv - Metagenesis vs Metamorphosis
Metagenesis thiab metamorphosis yog ob nqe lus hais txog kev loj hlob thiab lub neej voj voog ntawm cov kab mob. Metagenesis txhais tau tias yog kev hloov pauv ntawm kev sib deev thiab kev sib deev tiam neeg ntawm ib yam kabmob hauv lub neej. Metamorphosis yog txhais raws li tus txheej txheem nyob rau hauv uas kab mob qhia tau hais tias txawv cov qauv ntaub ntawv los yog txawv structural theem los ntawm cov neeg laus cov kab mob thaum lub sij hawm ib txwm kev loj hlob. Qhov no yog qhov sib txawv tseem ceeb ntawm metagenesis thiab metamorphosis. Muaj ob hom kev sib deev thiab kev sib deev nyob rau hauv lub neej voj voog ntawm cov kab mob uas qhia metagenesis whereas muaj plaub yam qauv tsim nyob rau hauv lub neej voj voog ntawm cov kab mob uas qhia metamorphosis.
Metagenesis yog dab tsi?
Nyob hauv qee cov nroj tsuag thiab tsiaj txhu, muaj ob tiam neeg hauv lub neej raws li kev sib deev thiab kev sib deev. Kev sib deev kev sib deev thiab kev yug me nyuam asexual hloov tau tshwm sim hauv lub neej voj voog. Qhov kev hloov ntawm kev sib deev thiab kev sib deev tiam neeg nyob rau hauv lub neej voj voog yog hu ua metagenesis. Nyob rau hauv ib tiam, cov nroj tsuag thiab tsiaj yug me nyuam asexually thiab nyob rau tiam tom ntej, lawv yug me nyuam kev sib deev. Yog li ntawd, cov qauv kev sib deev thiab asexual yog hloov pauv hauv tiam neeg. Qhov tshwj xeeb ntawm cov metagenesis yog tias ob hom diploid cov tib neeg tuaj yeem txheeb xyuas tau hauv lawv lub voj voog kev loj hlob vim tias ib qho yog tsim los ntawm kev sib deev thiab lwm yam yog kev sib deev.
Piv txwv li, metagenesis qhia los ntawm cnidarian Obelia muaj ob tiam (hloov thiab medusoid theem) qhov twg polyp tsim medusa asexually thiab medusa tsim polyp kev sib deev. Metagenesis tshwm sim hauv qee cov nroj tsuag (bryophytes) thiab. Nyob rau hauv mosses thiab ferns, muaj ob tug alternate kev sib deev thiab asexual tiam tam sim no. Lawv hu ua gametophyte tiam thiab tiam sporophyte.

Metamorphosis yog dab tsi?
Metamorphosis yog txheej txheem pom hauv qee cov tsiaj. Thaum lub sij hawm lub neej ntawm ib tug kab mob, yog hais tias nws muaj peev xwm txheeb xyuas cov ntaub ntawv sib txawv uas txawv ntawm cov neeg laus daim ntawv, nws yog hu ua metamorphosis. Ntau cov qauv sib txawv tuaj yeem raug txheeb xyuas qhov txawv ntawm lub neej voj voog tom qab lub embryonic theem thaum lub sij hawm kev loj hlob. Cov ntaub ntawv txawv no tau hloov pauv hauv lawv lub cev thiab cov kab mob hauv nruab nrog cev kom loj hlob mus rau hauv daim ntawv matured. Piv txwv li, npauj npaim qhia metamorphosis, thiab kev hloov pauv tau pom meej meej thaum nws lub neej voj voog. Muaj plaub hom qauv uas muaj npe hu ua qe, larvae, pupa thiab neeg laus (mature form) nyob rau hauv lub neej npauj npaim.
Metamorphosis tuaj yeem ua tiav (ua tiav) lossis tsis tiav (tsis tiav). Ua tiav metamorphosis muaj plaub hom: qe, larva, pupa, thiab neeg laus, raws li qhia los ntawm npauj npaim. Tsis tiav metamorphosis muaj cov ntaub ntawv uas zoo li daim ntawv loj hlob thaum lub sijhawm kev loj hlob. Lawv lub neej voj voog muaj peb hom qe, nymphs, thiab cov neeg laus; Piv txwv li, peb daim ntawv no tuaj yeem txheeb xyuas tau nyob rau hauv lub neej voj voog ib tus nyom nyom. Qe hatch rau hauv nymphs uas zoo li cov neeg paub tab tsis muaj tis thiab lub neej voj voog tsis suav nrog theem pupa. Nymphs qhia tib yam zaub mov zoo ib yam li cov neeg laus.

Summary – Metagenesis vs Metamorphosis
Cov ntsiab lus metagenesis thiab metamorphosis cuam tshuam rau cov yam ntxwv ntawm lub neej voj voog ntawm lub cev. Metagenesis yog qhov hloov pauv ntawm theem kev sib deev thiab theem asexual hauv lub neej voj voog ntawm lub cev. Kev sib deev thiab kev sib deev tiam neeg hloov pauv tshwm sim hauv lub neej voj voog. Metamorphosis yog ib qho tshwm sim uas qhia tau hais tias muaj ntau yam qauv sib txawv thaum lub sij hawm kev loj hlob ntawm cov neeg laus. Qhov no yog qhov sib txawv ntawm metagenesis thiab metamorphosis. Cov ntaub ntawv hauv metamorphosis txawv ntawm cov qauv thiab tus cwj pwm. Nws tuaj yeem tshwm sim hauv qhov zoo tag nrho lossis tsis zoo. Hauv metamorphosis zoo meej, plaub hom npe hu ua qe, larvae, pupa thiab neeg laus tuaj yeem txheeb xyuas. Hauv kev hloov pauv tsis zoo, peb hom npe hu ua qe, nymph, thiab neeg laus tuaj yeem txheeb xyuas.
