Qhov sib txawv tseem ceeb ntawm ametabolous thiab hemimetabolous yog ametabolous hais txog kab kev loj hlob uas tsis muaj metamorphosis thaum hemimetabolous hais txog kab kev loj hlob uas tsis tiav lossis ib nrab metamorphosis.
Metamorphosis yog cov xwm txheej uas cov kab tsim, loj hlob thiab hloov daim ntawv. Hauv cov lus yooj yim, nws yog cov kev hloov pauv tshwm sim hauv kab kab - los ntawm cov qe mus rau theem tsis paub tab mus rau cov neeg laus. Kab nrog ua tiav metamorphosis dhau mus rau plaub theem: qe, larvae, pupa, thiab neeg laus. Kab nrog metamorphosis yooj yim los yog tsis tiav tsuas muaj peb theem: qe, nymph thiab neeg laus. Qee cov kab tsis qhia metamorphosis. Muaj peb pawg kab raws li metamorphosis. Lawv yog ametabolous, hemimetabolous thiab holometabolous. Ametabolous kab tsis qhia metamorphosis thaum cov kab hemimetabolous qhia ib nrab metamorphosis.
Ametabolous yog dab tsi?
Ametabolous hais txog kab kev loj hlob yam tsis muaj metamorphosis. Yog li, kab hais tias yog ametabolic thaum tsis muaj metamorphosis. Nyob rau hauv kab ametabolic, cov kab hluas uas hatches los ntawm lub qe yog ib tug me me ntawm cov neeg laus. Lawv txawv ntawm cov neeg laus los ntawm kev muaj lub cev tsis muaj menyuam.
Daim duab 01: Ametabolous Kab
Tom qab ob peb moltings thiab loj hlob, cov theem tsis paub qab hau ua cov neeg laus. Yog li ntawd, cov theem tsis paub qab hau zoo ib yam li cov neeg laus. Hauv lwm lo lus, cov kab tsis paub qab hau zoo li cov kab me me ntawm lawv cov neeg laus. Cov kab qis xws li springtails, silverfish, thiab firebrats yog ametabolous.
Hemimetabolous yog dab tsi?
Hemimetabolous piav qhia txog kab kev txhim kho ntawm ib nrab metamorphosis lossis metamorphosis yooj yim. Cov kab no muaj peb theem hauv lawv lub neej. Lawv yog cov qe, nymph thiab neeg laus. Nymphs zoo li lawv cov neeg laus. Tsis tas li ntawd, nymphs pom tus cwj pwm zoo sib xws thiab feem ntau sib koom tib qhov chaw thiab zaub mov zoo li cov neeg laus.
Daim duab 02: Holometabolous vs. Hemimetabolous
Txoj kev hloov ntawm nymph rau cov neeg laus yog cov txheej txheem maj mam. Appendages, mouthparts, antennae thiab ob txhais ceg ntawm nymph loj hlob ncaj qha mus rau cov neeg laus. Kab xws li nas tsuag, mantids, cockroaches, termites, dragonflies, thiab tag nrho cov kab tseeb yog kab kab hemimetabolous.
Dab tsi zoo sib xws ntawm Ametabolous thiab Hemimetabolous?
- Ametabolous thiab hemimetabolous yog ob ntawm peb hom kab raws li metamorphosis.
- Ob hom muaj ob theem: qe thiab cov laus.
Qhov txawv ntawm Ametabolous thiab Hemimetabolous yog dab tsi?
Ametabolous piav qhia txog kab kev loj hlob uas kab tsis qhia metamorphosis. Lub caij no, hemimetabolous piav qhia txog kab kev loj hlob nyob rau hauv uas kab qhia ib nrab metamorphosis. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm ametabolous thiab hemimetabolous. Piv txwv li, feem ntau cov kab tis tsis muaj keeb kwm xws li silverfish yog kab ametabolous. Txawm li cas los xij, cov nyom nyom, kab kab tiag tiag, aphids, thiab kab kab nrog cov neeg laus tis nrog cov kab mob loj hlob tag nrho yog cov kab mob hemimetabolous.
Hauv qab infographic qhia txog qhov sib txawv ntawm ametabolous thiab hemimetabolous hauv daim ntawv teev npe.
Summary – Ametabolous vs Hemimetabolous
Hauv luv luv, ametabolous thiab hemimetabolous yog ob hom kab kab raws li metamorphosis. Hauv kab ametabolous, tsuas yog maj mam nce qhov loj ntawm cov theem tsis paub tab tuaj yeem pom mus txog rau cov neeg laus. Lawv tsis qhia metamorphosis. Silverfish, springtail, thiab lwm yam kab primitive yog kab ametabolous. Nyob rau hauv sib piv, hemimetabolous kab qhia ib nrab metamorphosis. Lawv lub neej voj voog muaj peb theem: qe, nymphs thiab neeg laus. Hauv no, nymphs zoo li cov neeg laus. Nymphs dhau los ua neeg laus tom qab moulting thiab loj hlob. Grassshoppers, mantids, cockroaches, termites, dragonflies, thiab tag nrho cov kab tiag tiag yog kab kab mob hemimetabolous. Yog li, qhov no qhia txog qhov sib txawv ntawm ametabolous thiab hemimetabolous.
