Ko te hanganga o ngā pūtau tangata: ohie ki te matatini

Ko rerekē i taua o te tahi atu kararehe rite te wahi o te tinana pūtau tangata, ki te whakaaro tatou ki te hanganga whānui anake o te mahere. Tātari i te hanganga o te pūtau o te tangata, i tāutuhia cytology e rua ngā wāhi e rerekē i roto i te mahi - te karihi, me te cytoplasm. ngā mahi o ia rā, te whakarite ngā hiahia tamau o te kōwae o mea ora katoa te mahi i te cytoplasm.

mahi motuhake katoa pērā i hukihuki o te pūtau uaua io tohu tuku ranei e whakamana ano e whakahaere te cytoplasm. Na reira, momo rerekē o te cytoplasm o ngā pūtau he rerekē. Na konei te taua i roto i te hanganga o te karihi noa i roto i ngā momo rerekē.

Ko te hanganga o te karihi pūtau feunga mangai i roto i nga wae ora o ngā momo rerekē. He kūtai ki o pūpūira me nucleoli. e kore te mea he pūhui matū pūpūira, he reira DNA tika "Kikī" āhua. Ko hoki te pūpūira te moka o te RNA me pūmua, histones.

Ko te nuinga o maha porohita porotītaha ranei te karihi. Ko reira he tapawhā, ka wehea e te constrictions hake (rite tupu i roto i te neutrophils). Whakaaro i te hanganga o te pūtau tangata, kia tuhia te reira e reira te vai te pūnaha membrane katoa, me te interphase (i waho te wehenga), kua karapotia tonu te pata i te kōpaki karihi. He rua i huaina kōputaputa karihi te anga. Na roto ratou ki te matua, me i te macromolecules haere.

whakaratohia matua i roto rerekē Wenerei i reo pūtau e kōputaputa diaphragms angiangi e tukua anake te taonga e hiahiatia ana ki te karihi. Na fetu'utaki te pata ki te cytoplasm o ngā mōhiohio matū. i hanga te nucleolus te rRNA tika mō te whakareatanga pūtau. maha hanumi nucleoli ki tetahi a taea te karu te kite i tetahi nucleolus nui.

wai karihi i roto i te hanganga matū - pūmua otinga colloidal, reira kino poke i roto i te taka mo te irahiko karu, ka puta rite te wāhi marama o nga photomicrographs. Ko te taiao tino korekore i ai ngä te tūringiringi o metabolites, a rawa hohoro taea rauemi ira neke.

Na te aha e te cytoplasm? I roto i ia "ohipa" e kore e ngā te whakahaere anake o uri, atu katoa e taea e ia. Ko te hanganga o ngā pūtau tangata pērā e te niu o te ora - hāora, e wahi i roto i te cytoplasm. Kei reira o maha hanganga iti, ka karanga organelles, ranei organelles, i faaauraa ki nga tinana o te tinana nui.

Te nuinga o organelles he hanganga membrane. Ehara i roto i kiriuhi anake ribosomes free, centrioles, ngä makawe me te flagella (katoa e toru ngā momo o organelles ngā o microtubules) me te hanganga fibrillar (microfilaments me fibrils).

Ko te hanganga o te membrane pūtau tangata, i roto i te parau tumu, e ko, e katia nga tari katoa kiriuhi. Pungaraungao, hei tauira, te tikanga e tito o rua ngā papa o kiriuhi, i nei te ariā o ngā rāpoi ngota pūngao - ATP rite ki te hua o ngā tauhohenga o te tukupūngao pūtau. He ahurei pungaraungao, no te mea he pirinoa e kua riro symbionts ratou. E ratou ratou ake genome, a te tikanga tino motuhake. Kei te riro te reira e kua heke ratou i huakita.

Ribosomes, e te tahi mau taime ngā i roto i polyribosomes, rave i roto i te kōtuitui o te pūmua, e tika ana hoki te cytoplasm. A ko reira rawa e tika ana, e kore anake ki te hanga hanganga, engari ano hoki i roto i te tikanga ki te pupuri i te toenga o te kaha osmotic he noa.

Ko te kiriuwhi ko te mirumiru, e he tūhonohono. Ko o te ribosome etahi o ratou. He pūmua synthesized e te e ratou, e kore e tere i roto i te wai o te cytoplasm - te cytosol, a kua taratahi i te pūtau i mua i hua mō te whakamahi i runga i ētahi atu hiahia ranei.

taputapu Golgi - te tahi mea rite te tāpae o peke. He E putu, ka kōmaka matū rerekē. Pūmua konei whiwhi tona hanganga whakamutunga, me te te konei reira i hanga lysosomes.

A paraparau o te lysosomes. whakangaromia ratou wāhanga pūtau e hiahiatia, ki te he he ki a ratou te tahi mea, ka whakawhanake mate rokiroki. I muri i te matenga o te pūtau, e whakangaro ratou te taiao wae ora mate noa mate, e kore e tika ia.

Ko rerekē i te hanganga o te hunga mate i roto i te wahi tuatahi e tae mai ki karyolysis mate te hanganga o ngā pūtau ora - te mimiti haere o te nucleus me nga tirotiro pūtau i muri i kiriuhi nakunaku resorption lysosomal.
