He aha te gamete me whakatō kākano: āhuatanga hanganga

Mai i tēnei tuhinga, ka ako koe ki ta te gamete. Ko te pūtau motuhake, e mahi tino motuhake tenei. He aha e ratou? Kia a mahi tahi.

He aha te mea gamete: Definition

I roto i te reo Kariki te tikanga te wā "wahine" ranei "tane". E kore taea e te reira atu tika whakatau tona uara. Gamete - he pūtau sex. I roto i te natura, i reira e rua ngā momo o reira - tangata me nga wahine.

I roto i tetahi take e hanga e na roto i te wehewehe i te pūtau iroriki primordial tohuhema. Heoi, kei te rongoa ratou huinga pūira diploid. ai tenei he hua i roto i to ratou tau. He rerekētanga nui ki te tukanga o te hanganga o tohuhema tane, he wahine. Ko te kupu, kotahi parāoa tuatahi e hanga e wha ki tonu i ngā pūtau e taea o te kikiritanga. I roto i te wahine tohuhema e whiwhi kaha kotahi anake hua manu.

Ko te hanganga o te hua manu

He aha te mea te gamete o te tinana wahine? Ko reira tonu te pūtau whakaritea kei roto i te supply tika o ngā matūkai faufaa mo te whanaketanga o te rauropi heke mai. He he āhua porotaka porohita ranei. tiakina te hua i roto i te maha o ngā anga: te toene, me te waho mārama. Ko tōna cytoplasm - te inclusions pātaka toene reira.

Āhuatanga o te pūtau iroriki toa

Na kia kite a he aha te mea te momo gamete tane. pūtau parāoa e tonu nui iti whakaritea ki nga hua. Ko e tika ana ki te meka e roto i tohuhema toa te mōhiohio iranga anake tenei. He aha e tangohia e ratou o ngā matūkai? Ko te take i te pūtake mo te heke mai o te tinana, ko te tika i te hua manu, e kua nui o ratou.

Tohuhema o ngā tipu me ngā kararehe: ōritenga me ngā rerekētanga

He pūkoro tohuhema tane o te kararehe. E hanga pūtau parāoa ake o e toru ngā wāhanga: upoko, kaki, me te hiawero. Kei te kotahi tuatahi he karihi. Ko te huinga pūira haploid, ranei kotahi. He angamaheni o ngā pūtau iroriki tenei āhuatanga hanganga. Kei roto hoki te matenga o te acrosome parāoa, ranei te tinana apical. Tenei organelle hua he paru motuhake, i te mea nehenehe o tātau te anga paruru o te hua manu. Ko te waha ko te centrioles me pungaraungao. hua ratou i te pūngao e hiahiatia ana ki te pei i te hiku.

E huaina tohuhema Plant tane parāoa. I roto i te māngai uri teitei o te kingitanga ko ratou i roto i nga pito o te pūtawa. neke ratou i te hau, pepeke te tangata ranei. Ko te tukanga o te whakawhiti ratou ki te tauhae o te pistil i huaina ruingahae.

He aha te mea te gamete o ngā tipu me te wahi e kei reira? Ki te korero tatou e pā ana ki te hua manu, ko reira, me te rite i roto i te tipu, pahoho porotītaha whare herehere. Kei i te raro o te wahi whānui o te puawai pistil. Ki tohuhema hanumi, kei te oho te parāoa ki te rua gamete wahine rite tupu iroriki ngongo. Ka rite ki te hua o te kikiritanga i hanga uri.

I roto i te teitei tipu spore pakari ngā pūtau iroriki ki whēkau motuhake - gametangia. I roto i enei rauropi, he mārama whakarerekētanga o whakatupuranga puta i roto i te huringa ora.

Kia whakaaro tatou i tenei tukanga i te hi'oraa o talingelingá. māngai tona whakatupuranga fakasekisualé ko e te "whāriki" matomato. Kei a ia ko te tipu pururu kotahi. E hanga e ratou me gametophytes i ai te pūtau iroriki pakeke. Ka rite ki te hua, te tukanga o te kikiritanga, mo te whakatinanatanga o nei titau wai, tupu whakatupuranga tōtahi - sporophyte. He te puka o ngā pouaka i runga i te kakau maroke. pakari te reira i ngā pūtau o te whakaputa uri tōtahi, e te hunga kua huaina pua. whiwhi ratou ki te oneone, me te ka hoatu ara ki te gametophyte. Na whai ngā wāhanga huringa ora tahi e te tahi.

Ko te hua o te kikiritanga

huaina te hua manu wairakau te he kākano. Ko tōna huinga pūira ko kua diploid, rua ranei. I roto i te kararehe, he waho, me te ā-kikiritanga. I roto i te take tuatahi, e te reira wahi i waho o te tinana wahine. he angamaheni hoki ika me amphibians he tikanga taua. A, no te te kikiritanga ā-o whakamōhio te tane te whakamahi i te whekau copulative parāoa ki te tinana o te wahine. He puta me te whanaketanga fetal, kia ko atu ahu whakamua tenei tikanga.

I roto i ngā tipu, te uaua tino o tohuhema hanumi kitea tukanga i roto i te pua. Kei te karanga a te reira i te rua, no te mea hono te parāoa te gamete wahine, me te pūtau iroriki pokapū. Ko te hua ko te kukune, te matūkai e manawapa i huaina endosperm, me kiri. A tahi katoa - te purapura.

tīmata te whakatō kākano ki wehe. ngā tenei te ira. Tuatahi, ngā reira o paparanga kotahi. Kei te karanga a te reira i te blastula. Reira ka tīmata whakapanga kopa me whēkau o te heke mai. I roto i tenei wā i huaina e ia gastrula. Ko te hanganga o te ira whakapanga toru paparanga iroriki, e whakawhanake i whēkau me ngā pūnaha motuhake.

Na, i roto i tenei tuhinga ka titiro tatou ki te mea i te tohuhema me whakatō kākano. Enei hanganga Ko nga kawe o ngā mōhiohio tuku, me te hoatu ara ki te rauropi hou.
