Zotsatira Tizilombo: metamorphosis - izo ...

Kwenikweni, ndi metamorphosis - kusandulika aliyense, kusintha chikuchitika mu chilengedwe chonse. Mawu amenewa ndi ofanana kwambiri ndi ntchito zosiyanasiyana za sayansi. M'nkhaniyi tiona mfundo ku mawonedwe a zamoyo. Mwa sayansi moyo chodabwitsa molondola lotchedwa "metamorphosis", mu osonyeza chachimuna, adzapitiriza ntchito options onse zotheka.

Choncho, mu zamoyo wa metamorphosis - ndi kutchulidwa morphological kusintha kwa zamoyo, kwenikweni zikuchitika pa ontogeny ake. Chodabwitsa amapezeka zomera ndi nyama. Mu metamorphosis posachedwapa amapezeka kayendedwe ka moyo wa invertebrates kwambiri ndi ena inakhala: cyclostomes, nsomba, achule. Akamanena za ndondomeko ndi kutembenuza lake larval (nyama) kapena ziwalo zina (zomera) kotero kuti omasuka wamkulu chamoyo chifukwa kwambiri wosiyana dongosolo wakhanda, Maphunziro Akakhalidwe Kazolengedwa ndi ntchito.

Animal metamorphosis - si kusintha lakuthwa mu dongosolo thupi. chodabwitsa The limodzi ndi kusintha malo okhala ndi moyo zinthu. Vital ntchito za chamoyo wamkulu ndi osiyana ndi zimene magawo larval, kusiyana lagona mu malo, kumwa chakudya ndi zinthu zina zambiri. Choncho, ife tikupeza metamorphosis zofunika mu chikhalidwe, ithandiza kuchepetsa mpikisano kwachilengedwenso chakudya, malo okhala komanso zinthu zina pakati pa zamoyo za mibadwo yosiyana ya mtundu womwewo.

Tiyeni tikambirane metamorphosis nyama. Chitsanzo chidwi kwambiri mwina kalasi ya tizilombo. Metamorphoses wamba ndi anthu onse a m'gulu limeneli. Dongosololi mwina wathunthu kutembenuka kapena chosakwanira. Complete metamorphosis kumafuna magawo atatu a chitukuko cha chamoyo: nyongolotsi-ngati larva, pupa (n'kupuma gawo, imene thupi inawonongedwa mphutsi ndipo anapanga thupi latsopano la wamkulu) ndi tizilombo wamkulu. Mtundu wa chodabwitsa ndi khalidwe la Diptera (ntchentche, udzudzu), Hymenoptera (njuchi, bumblebees, mavu), Lepidoptera (agulugufe), kafadala (ladybugs). Ndi metamorphosis chosakwanira, pali kokha magawo awiri: larva, ofanana ndi kafukufuku wakapangidwe kazachilengedwe wamkulu, ndi zoona, tizilombo wamkulu. Chosakwanira kutembenuka khalidwe Orthoptera (dzombe, ziwala, Mole crickets), Homoptera (nsabwe) ndi Hemiptera (nsikidzi).

Zomera apamwamba metamorphosis - ndi kusinthidwa ziwalo zina zokhudza ntchito iwo kuchita, osati kusintha kwa lake lonse. Monga ulamuliro, m'kati kulowa embryonic, osati ziwalo athanzi. chomera metamorphosis amatchedwanso zosintha. Mwachitsanzo, babu (mu uta), spines (nkhadze), masharubu (pakuti mphesa), pomwepo kenaka (ginger wodula bwino mu), tubers (mbatata), ndipo kwambiri. Kutanthauza metamorphosis zomera zili anatengera awo mmene chilengedwe. Mwachitsanzo, spines (kusinthidwa masamba) kunachitika zomera tikukhala mu nyengo yotentha, mawonekedwe ake kuchepetsa evaporation padziko pepalalo.
