Pūtau Haploid: āhuatanga, wehenga, whakarea

pūtau Haploid - ko tenei, i te matua o e kei te huinga kotahi o pūira. te, waiwai, te tohuhema reira - e ko, pūtau tikanga hoki tupuranga. Hoki huinga haploid o pūira i te rauropi tino prokaryotic. pūtau Somatic o eukaryotes (katoa anake sex) - kia polyploid tipu diploid.

Ko te hanganga o ngā pūtau prokaryotic

Prokaryotes he kaiao, arā, o te pūtau kotahi, i roto i nei kahore matua. Ēnei ngā huakita anake. Te nuinga o ratou i te huinga kotahi o pūira.

Ko rerekē i te meka e hapa reira etahi o nga organelles Hanganga o ngā pūtau eukaryotic. Hei tauira, e kore ratou e whai pungaraungao, lysosomes, Golgi taputapu, miru, kiriuwhi. Heoi, ka rite ki te eukaryotic, he pūtau haploid prokaryotic wē membrane arā, o pūmua me phospholipids; ribosomes, whai wāhi i roto i te whanaketanga o te pūmua; taiepa pūtau, e i roto i te nuinga o te wā i hangaia o murein te. Ano pea te capsule hakari i roto i te taua hanganga pūtau, e ngā matū pērā i pūmua, me te kūhuka. rewa ratou pūira noa i roto i te cytoplasm, karihi, ranei kahore e tiakina e tetahi atu hanganga. Nuinga o ngā wā, māngai te rauemi tuku o huakita e tetahi anake pūira, i runga i nei tuhia ngā mōhiohio kei runga i te pūmua e he ki kia whakaputaina e te pūtau. Tikanga whakatö o taua rauropi - he wehenga ohie o te pūtau haploid. Tenei taea ratou i roto i te wa poto ake i tino ratou tau.

pūtau eukaryotic he te huinga kotahi o pūira

I roto i tenei ahua o rauropi i roto i karihi haploid pūtau huaina tohuhema. kia waiho ratou rerekē tino i te somatic. Reproduction he fakasekisualé pūtau haploid, a taea tīmata te tinana hou ki te whakawhanake anake i te kongutu o rua tohuhema, synthesized e takitahi rerekē o te taua momo.

I hanga i te taha o te hononga o rua pūtau haploid i huaina he kākano, reira kua roaa te huinga rua o pūira. Ahakoa te meka e he rerekē i te diploid somatic nga pūtau iroriki, kia tonu i ratou etahi organelles tūturu i roto i eukaryotes.

tohuhema kararehe

pūtau Sex o kaiao no ki te kingitanga, ka karanga te parāoa me te hua manu. hua tuatahi i roto i te tinana o te tane, te tuarua - wahine. Hua hua i roto i te ovaries me ngā pūtau parāoa - i roto i te komurumurua. Na te hunga me etahi - pūtau haploid motuhake, e whai mahi rerekē.

Ko te hanganga o te hua manu

pūtau sex Wahine whai āhuatanga nui nui atu i nga tangata. E whakaritea ratou. Ratou mahi matua - ki te whakarato i te whakatō kākano mo te wa tuatahi nga matūkai e hiahiatia ana mo te wehenga. Kei te hua manu o cytoplasm, membrane, anga gelatinous tinana neke me te karihi, e kei pūira e mau ana ngā mōhiohio tuku. i roto i tona hanganga ano kei roto granules cortical e roto i whākōkī, ārai atu parāoa ki te pūtau i muri i te kikiritanga, ranei i taea te hanga e whakatō kākano polyploid (ki te takitoru, me te huinga o pūira), e titauhia katoa o irakētanga.

taea hoki te whakaaro hua Egg manu, engari kei roto te reira i nui atu ngā matūkai ki te kia nui hoki te whanaketanga tonu o te ira. pūtau iroriki Wahine o kararehe kei maha matū organic, pera i roto i nga wāhanga i muri mai o te whanaketanga o te ira i roto i te ewe, e tango ia i te tika katoa i te whaea.

I roto i te take o te manu e kore e, pera te supply katoa o ngā matūkai me te tīmatanga kia reira hakari i roto i te hua manu. Ko te hua manu he hanganga matatini ake. I te tihi o hipoki te pūwhera toene me te anga pūmua kei ki te anga, e kua he mahi tiaki he reira i roto i te hanganga o te ruma rangi, i te mea e tika ana mo te hāora kukune hoki.

Ko te hanganga o te parāoa

Ko pūtau haploid tikanga mō te tupuranga hoki tenei. Ko tōna mahi matua ko te tiaki me te tuku o te rauemi tuku pāpā. Tenei pūtau haploid te pūkoro he rahi nui iti ake i te hua manu, e te meka e kei reira kahore matūkai.

Kei parāoa o te maha ngā wāhanga matua: te hiku, me te matenga o te therebetween kāri takawaenga. Hiku (pihi) tito te o microtubules - hanganga i hanga i roto i o pūmua. Ngā mihi ki a ia, ka taea e te parāoa neke ki tona whāinga - te hua manu, e me wairakau ia.

Intermediate wehea i waenganui i te upoko me te hiawero kei pungaraungao, e kua whakaritea helically huri noa te wahi waenganui o te pihi, me te rua o centrioles teka hāngai ki tahi i te tahi.

Ko te tuatahi - organelles reira taua hua pūngao, i te mea e tika ana mo te kaupapa o tohuhema. Ko te upoko parāoa he kākano e kua he huinga haploid o pūira (23 i roto i te tangata). I runga i te waho o tenei wahi o te pūtau whakaputa uri toa he autosome. I roto i te meka, te paku whakarerekē reira, nui haere lysosome. Kei reira whākōkī e e faufaa ki parāoa taea tareka wahi o te hua manu anga waho, me te he wairakau reira. I muri i te gamete toa hanumi ki te wahine, i hanga te whakatō kākano e e roaa te maha diploid o pūira (46 i roto i te tangata). He te kaha ki te wehe, me te hanga i reira kukune.

pūtau tipu Haploid

Kaiao o tenei "basileia" e whakawhanakehia ngā pūtau uri rite. Wahine, rawa, kua karangatia e hua, me te tangata - parāoa. Ko te tuatahi i roto i te pistil, me te tuarua - i runga i nga hematoa, hae. I muri whakapā i runga i tona kikiritanga pepe puta, a ka hanga e hua ki te purapura i roto.

I roto i ngā tipu o raro (spore) - talingelingá, kaponga - i reira ko te whakarerekētanga o whakatupuranga. Ko tētahi whakamahi asexually (pua), me te tahi atu - moepuku. huaina ana te tuatahi ko te sporophyte, me te tuarua - gametophyte. aroaro matou aruhe tipu sporophyte ki ngā rau nui, i te gametophyte - hanganga matomato iti i roto i te āhua o te ngakau ki runga i te reira, me nga pūtau takoto e hanga e.
