Ka taea e Plastids kia rerekē: momo, hanganga, mahi

He tokomaha te pakeke te mohio he aha nga plastids i te kura. I roto i te akoranga o Botany ta e i roto i te pūtau tipu, kia te plastids o rerekē āhua, te rahi, me te mahi i ngā mahi rerekē i roto i te pūtau. Te faahaamana'o nei teie tuhinga koutou o te hanganga o te plastids, ratou puka me mahi o te hunga e kua puta kē i te kura nui, a ka whai hua ki te tangata hiahia i roto i te koiora.

hanganga

E whakaatu ana te pikitia i raro nei te hanganga schematic o te plastids i roto i te pūtau. Ahakoa o tona ahua, kua reira te membrane waho, me te ā, he mahi tiaki, stroma - orotahi cytoplasm whākōkī DNA rāpoi ngota ribosomal.

I roto i te chloroplasts reira he hanganga motuhake - grana. thylakoids Grana i hanga i - hanganga, rite ki te kōpae. E whai wāhi Thylakoids i te ariā o te ATP me te hāora.

I roto i te chloroplasts e hanga e granules māngaro rite ki te hua o te ahotakakame.

Leucoplasts kore pigmented. mahi ratou thylakoids kore reira, e kore ratou e tango i tetahi wahi i roto i te ahotakakame. Te nuinga o leucoplasts hāngai i roto i te kakau me te pakiaka o te tipu.

E tito Chromoplasts o rūrūtia lipid - hanganga kei roto lipids tika ki te tuku hanganga pūngao atu o plastids.

Ka taea e Plastids kia rerekē ngā tae, te rahi me te āhua. Ratou rahi ngā waenganui i 5-10 microns. Ko te āhua he te tikanga a tawhio porotītaha ranei, engari kia waiho tetahi atu.

momo o plastids

Ka taea e Plastids e taekore (leucoplasts), matomato (chloroplasts), kōwhai karaka ranei (chromoplasts). E horo'a te reira chloroplasts o te tipu rau matomato.

Ko tētahi atu momo o plastids, chromoplasts, he kawenga hoki te tae kōwhai, whero karaka ranei.

plastids taekore i roto i te pūtau te mahi o te rokiroki matūkai. E roto Leucoplasts i roto i te ngako, starches, pūmua me whākōkī. A, no te Me te whakato pūngao atu ki te wahia te waetahi māngaro - kūhuka.

Ka taea te tahuri Leucoplasts i raro i etahi tikanga (e te rā mā te tāpiri matū ranei) ki te pūkano tipumata, ae whakaputaia ketia ana chloroplasts ki chromoplasts, i te whakangaromanga a chlorophyll te me i tae timata uhi ki te nuinga chromoplasts - Peta, anthocyanin xanthophyll ranei. Ko te kite tenei tauiraa i roto i te ngahuru, ka nga rau, me hua o maha tae huringa tika ki te whakangaromanga o ngā uhi chlorophyll me faaiteraa chromoplasts.

mahi

Ka rite ki whakahuatia i runga ake, ka taea e plastids kia rerekē, me o ratou mahi i roto i te pūtau tipu rānei i runga i te momo.

E whakamahia Leucoplasts matua mō te rokiroki o ngā matūkai me te tautoko whakato ora e tika ana ki te āheinga ki te rokiroki me te synthesize pūmua, lipids, whākōkī.

Chloroplasts tākaro he wāhi matua i roto i te tukanga o te ahotakakame. Ki te te āwhina o te chlorophyll ngarahu takiwa i roto i nga plastids o te hauhā e wahi me te faafariuraa o te rāpoi ngota wai i roto i te rāpoi ngota kūhuka i me te hāora.

Chromoplasts whakawhetai ki tae kanapa kukume ngārara mō te ruingahae. A tuatapapa i te mahi o enei plastids he tonu haere tonu.
