Tipu pūtautahi: tauira me ngā āhuatanga

Kua wehea rauropi katoa i runga i te whenua ki ngā rōpū nui e rua - pūtau me te kore-pūtau. Ko te whakamutunga ngā wheori anake, engari ki te tuatahi - te tahi atu mea ora katoa. kia eukaryotic te pūtau (i te hanganga o te karihi pūtau) prokaryotic (matua tuimotu) ranei. Ko te whakamutunga e māngai e te huakita, ko te tuatahi ki te whakauru i ētahi atu rōpū katoa o mea. hanga te hanganga o te nuinga o ratou kei te ake o ngā pūtau maha, engari i reira e i roto i tenei rōpū o kaiao pūtau-tahi, otaota, harore, a tae noa kararehe. ngā te whakamutunga Pūora, ciliates, harore - rewena, Mucor, Penicillium.

Ko te hanganga o te pūtau tipu pūtau-tahi

Enei rauropi he eukaryotes, e ko, ko to ratou DNA i roto i te karihi, e kua he mahi tiaki. Ka rite ki ngā pūtau tipu katoa, i roto i ratou organelles motuhake pērā i vacuoles me plastids. i roto i to ratou hanganga ano ngā o te pungaraungao, lysosomes, ribosomes, Golgi taputapu me te kiriuwhi, arā, he huinga o organelles, te paerewa mō eukaryotes katoa.

mahi o organelles

Pungaraungao kawe i tetahi o nga tūranga tino nui i roto i te pūtau - hua ratou pūngao mō ngā tukanga ora katoa. He kawenga mō te nakunaku intracellular o ngā matūkai Lysosomes. Mahi e ribosomal te kōtuitanga pūmua i waikawa amino takitahi.

Te Golgi synthesize etahi rāpoi ngota, me te kōmaka pūtau rauemi katoa whakawhanakehia.

Kei te whai wāhi hoki kiriuwhi i te pākia e, piki kohuke synthesizing lipids me phospholipids. Organelles e te hunga ahurei ki whakatokia pūtau, ka mahi i ngā mahi ōrite nui. I roto i te tukanga o te ahotakakame puta chloroplasts, vacuoles me mahi tūranga tank mō matū faufaa pūtau.

otaota pūtautahi. tauira

Tenei ahua o rauropi he piha pükohu. Ko te tauira tino Tūrongo ko te tipu chlamydomonas pūtau-tahi. kia hoki tenei ngā chlorella me ngā momo o diatoms.

hanganga āhuatanga

tipu pūtautahi o ngā momo rerekē i to ratou ake ngā āhuatanga motuhake. Ahakoa ngā ratou katoa o te pūtau kotahi, engari kia whai ratou ake āhuatanga motuhake.

Chlamydomonas - te māngai tino rongonui o te pükohu rauropi pūtau. rerekē ratou i te ētahi atu i roto i taua kua reira taua organelles rite te kanohi marama-tairongo, i nei e taea kaiao whakatau te wahi i reira he nui ake te pūngao kōmaru mō te ahotakakame. Engari, maha chloroplasts to ratou tetahi nui, ka karanga chromatophores. i roto i to ratou hanganga ano ngā o te miru contractile. mahi ratou rite papua e te papu i te wai i te taikaha. I tua atu, kua ratou e rua flagella, organelles e tukua te tinana ki te neke i roto i te ahunga o te marama. Tetahi otaota kotahi-tahi - chlorella.

Ka rite ki Chlamydomonas, he ratou pükohu matomato, engari e kore e whai pera maha organelles motuhake, pera kaiao whakaahuatia ana i runga. Ratou pūtau - huawhenua angamaheni.

Diatoms tono hoki ki te tipu pūtau-tahi. Ko ratou he wāhanga nui o te köurarangi e ora i roto i te tinana nui o te wai. E ratou he membrane pūtau motuhake e tiaki te tinana i te taiao o waho. Kei a ia ko te hāorarua o silicon, waikura o rino, konumohe, me te tahi atu pūhui. Mai i nga toenga o nga anga e hanga e o kohuke maha. Ko te nuinga o te tipu pūtau-tahi whakaputa uri ara wehenga. taua rauropi katoa whiwhi ratou matūkai i roto i te ahotakakame, arā, he autotrophs ratou.
