He aha ētahi chloroplast e riro ana? I runga i te pātai o mua, tuhia he horopaki kei roto te whakautu. Ka taea te 1 - 20 rerenga kōrero. Te horopaki:
He mea whakamīharo, kāore te haurua o ngā hua pūmua o ngā ira kua whakawhitia e whakahokia mai ki te chloroplast. He tokomaha i riro hei exaptations, e whai ana i ngā mahi hou pēnei i te whai wāhi ki te wehenga pūtau, te whakawhiti pūmua, tae atu ki te ātete mate. He torutoru nga ira chloroplast i kitea he whare hou i roto i te huinga ira mitochondrial - ko te nuinga i noho hei pseudogenes kore mahi, ahakoa he torutoru nga ira tRNA e mahi tonu ana i roto i te mitochondrion. Ko ētahi hua pūmua DNA chloroplast i whakawhitihia ka whakahaeretia ki te ara whakakorenga (ahakoa me tohu he maha nga plastids tuarua e herea ana e te kiriuhi o waho i ahu mai i te kiriuhi pūtau o te kaihautū, na reira kei waho o te pūtau, na te mea ki te tae atu ki te chloroplast mai i te cytosol, me whiti koe i te kiriuhi pūtau, me te mea kei te haere koe ki te waahi o waho. I aua take, ko nga pūmua e whaaia ana e te chloroplast ka haere tuatahi i te ara whakakorenga).
