Organelles o ngā pūtau, me o ratou mahi: momo, mahi me ngā āhuatanga

Whare herehere - te wae o te ora i runga i to tatou paraneta, i reira he ora o te pūtau. Ko Ko te aha te mahi āhuatanga katoa o ngā kaiao takoto i runga i te pūtake o ngā āhuatanga o ngā pūtau e tautuhi organelles pūtau me o ratou mahi.

Mai i te huinga o ngā pūtau āhuatanga tino nui ko: te hanganga pai-tautuhi, kaha ki te metabolize - whakaputa pākia e me te pūngao, ki te kaha urupare ki akiaki waho: te taonga me te ari. I tua atu, i te organelles mahi pūtau whakatau āhuatanga pērā i te āheinga mō te tipu me te whanaketanga, me te te whakatö me whakaora - houtanga.

Just rite te kararehe he tipu ranei ngā o te maha okana me ngā pūnaha, ngā te pūtau o organelles. Whakaaro i te organelles pūtau me o ratou mahi, he mea nui ki te mōhio i te waho hanganga o ngā pūtau. Waho "te ora tūemi" pani ki te membrane i tavini rite te arai rohe wehe i te taiao i waho i te tirotiro ā-o te pūtau. Ko te membrane he mahi tiaki, me te rohe, me te e tango hoki akiaki ambient (receptor mahi) me te mauria i waka o matū.

organelles Cell, ratou hanganga me te mahi

e kua te oraraa o te pūtau, me ona wāhanga kua taea ki te kore te roto i ki tonu ai ki te wai motuhake - cytoplasm. hua te reira i waka cytoplasm o matū i roto i ngā pūtau, rite toto me te te tīpona i roto i te tinana. I roto i tenei take, mahia te cytoplasm pānga pāhekoheko intercellular tika ki ngā momo o ngā tukanga, ngä makawe fluff. Kia wāhanga o enei tukanga (hei tauira, flagella ngä makawe iti ranei) te mahi i te mahi pūkaha ki ētahi atu outgrowths pūtau e kore ahei o te kaupapa.

Pungaraungao - tetahi o nga organelles pūtau tino nui wāhi i roto i te tukanga manawa "wae o te ora", me te tahuri ngā momo o te pūngao i roto i te puka i te mea e wātea ana mo te pūtau. I roto i te meka, te pungaraungao - ko te pūtau he turanga pūngao, me reira te nui o organelles raraunga tei runga i te mahi whakamana i te pūtau, a ko te kupu, i ona hiahia i roto i ngā rauemi pūngao. Ko reira taa'eraa e roto i pungaraungao ratou ake mekameka DNA, ai runga ki te 2% DNA takiwa o te pūtau.

Ko tētahi atu organelle whai wāhi i roto i te tukanga o te pākia e - te ribosome. Ko tenei āhuatanga o te pūtau hua te kōtuitui pūmua. Mea nui, e kitea i roto i ngā pūtau katoa o te tinana tangata, ki te kahore pūtau toto whero nga pūmua. E whakaritea Ribosomes noa i roto i te cytoplasm, ka whai pānga te tukanga ariā pūmua i te tītohunga transcriptional - tārua i te mōhiohio tuhia nei te i roto i te DNA.

organelles pūtau me o ratou mahi e whai kahore tikanga i roto i te natura, ki te kahore he karihi o te pūtau. Ko te faahiahia tenei organelle i roto i taua kei reira he mea tino nui - te pūpūira, i te mea te pūtake mo te hanganga o ngā pūira. pūira te reira i tuku i te mōhiohio iranga o te pūtau i roto i te whakaputa uri. Na reira i hanga DNA pūpūira te me te nui iti o te RNA. I tua atu, i te hanganga o te matua tomo te nucleolus - he tinana, i roto i nei te ariā o ribosomes hou. āhuatanga Nucleolus tēnā i runga i te āhua o kaha haere te kōtuitanga pūmua i roto i te pūtau.

I roto i te mutunga, whakaaro nga organelles pūtau me o ratou mahi, he mea tino uaua ki te tāutu i tetahi tetahi "wae o te tinana ora", e taea te whakaritea rangatira. whakaaro matua conventionally, tīpakohia tenei organelle te rite te tinana tangata ko te ngakau nui. I roto i te vairaa mau, te tautoko nga organelles katoa he momo o te matū, ngā tukanga tinana, me te koiora, na e mahi o te pūtau, a reira ko te huinga o ngā mahi rerekē e kua ngā raro i te wā kano o te ora.
