Eukaryotes - He rauropi i te karihi nei pūtau

Eukaryotes - te nuinga o kaiao whakaritea ahu whakamua. I roto i tēnei tuhinga ka titiro tatou ki no tetahi o nga māngai o kararehe ki tenei rōpū, me te aha ngā āhuatanga kua whakaaetia te whakahaere ki te tango ia ratou i te tūranga tino i roto i te ao organic.

Ko wai e nga eukaryotes

E ai ki te whakamāramatanga o te ariā, eukaryotes - he rauropi i roto i te karihi whakairo nei ngā pūtau. Ēnei ngā nga rangatiratanga e whai ake nei: tipu, kararehe, harore. Na noa'tu te pakeke whakaritea ratou tinana te. Te Pūora mōkitokito, koroni Volvox, sequoia nui - eukaryotes katoa.

Ahakoa he te tahi mau taime enei pūtau kia tangohia te kopa o te karihi. Hei tauira, ehara i te mea i roto i te pūtau toto whero. Engari, kei roto tenei pūtau toto pūtoto kawe hāora me te hauhā. Kei roto ēnei pūtau he karihi anake i roto i te tīmatanga o tona whanaketanga. Na, kua ngaro tenei organelle, a ki reira, a ka ngaro i te kaha ki te wehe i te hanganga katoa. Na reira, na roto i te raveraa i ona mahi, mate taua pūtau.

hanganga o te eukaryotic

I roto i te pūtau o eukaryotes i te karihi. A te tahi mau taime e kore noa tetahi. Kei tēnei organelle dvumembrannaya i roto i tona kopu te mōhiohio iranga whakawaeheretia i roto i te rāpoi ngota pītauira. Kei te matua o te kōwae mata, e whakarato ana waka o matū, me te kopu - o tona taiao ā-. Ko te mahi matua o tenei hanganga - rokiroki o mōhiohio ā-ira, me tona whakawhiti ki ngā pūtau tamahine hua i te wehenga.

reo matua i roto ko wāhanga maha. Tuatahi o te karyoplasm reira katoa. Kei reira nucleoli me pūpūira whenu. ngā te whakamutunga o te pūmua, me te waikawa karihi. I hanga e te reira i ka Helix te pūira. Ratou e tika kawe o ngā mōhiohio ā-ira. Eukaryotes - he kaiao i roto i nei kia hanga e nga momo e rua o otaota i roto i ētahi wā: vegetative me generative. He tauira a Tūrongo, o tenei - ciliate. Ko tōna matua generative tiaki mahi me te tuku o te tohuira, me vegetative - ture o te pūmua biosynthesis.

Ko te rerekētanga matua o tei me eukaryotes

Kua tukuna ngā prokaryotes te karihi. Tenei rōpū o kaiao ko te pono anake kingitanga o te natura - Bacteria. Ko taua hanganga āhuatanga e kore e tikanga e i roto i te pūtau o enei rauropi he kahore kawe o ngā mōhiohio ā-ira. Bacteria Kei roto rāpoi porohita o te DNA - plasmid. Heoi, kei te whakaritea e ratou i roto i te puka o tautau i roto i te wahi etahi o te cytoplasm me kahore kōpaki noa. huaina te hanganga taua te nucleoid. He ko tetahi rerekētanga. e kore te DNA i roto i ngā pūtau prokaryotic e pā ana ki pūmua matua. Kua whakapumautia pūtaiao te oraraa o plasmids i te pūtau o eukaryotes. Ko ratou i roto i te tahi mau organelles āhua-motuhake, pērā i pungaraungao me plastids.

Progressive hanganga āhuatanga

Eukaryotes he kaiao e he āhuatanga matatini ake o te hanganga i ngā taumata katoa o te whakahaere. Tuatahi o te katoa āwangawanga reira te tikanga roha. huakita Nucleoid whakarato te māmā o ratou - te wehenga o te pūtau ki rua. Eukaryotes - kaiao e he nehenehe o me ki ngā momo katoa o te uri o ratou ake ahua: fakasekisualé, me te paratau, parthenogenesis, conjugation. E whakarato ana i mo te utu o te mōhiohio ā-ira, te putanga me te whakatōpū i roto i te tohuira o te maha o ngā āhuatanga whai hua, a konei he urutaunga pai ki tonu-te huri ngā āhuatanga taiao. Tēnei āhuatanga me eukaryotes whakaaetia ki te noho i te tūranga tino i roto i te pūnaha organic ao.

Na he kaiao i te karihi whakapaipai nei pūtau eukaryotes. Ēnei ngā tipu, kararehe me harore. Ko te āhuatanga ahu whakamua o te whare te aroaro o te matua, te whakarato i te taumata tiketike o te whanaketanga me te urutaunga.
