Tauira o tētahi Pātai Kōrero mō te Kawe i roto i ngā Tipu
He kaupapa nui te kawe i roto i ngā tipu i roto i te koiora, inā koa mō ngā ākonga kura tuarua. Ka tūhuratia e tēnei kaupapa te neke me te tohatoha o ngā tipu i ngā matū e tika ana mō tō rātou tipu me te whanaketanga. I roto i tēnei tuhinga, ka tirohia e mātou ētahi tauira raruraru me ō rātou whakamārama hei āwhina i ngā ākonga ki te mārama ake ki te ariā o te kawe i roto i ngā tipu.
He Kupu Whakataki ki te Kawe i roto i ngā Tipu
E rua ngā wāhanga matua o te kawe i roto i ngā tipu: te kawe i waenga i ngā pūtau me te kawe tawhiti. Ko te kawe i waenga i ngā pūtau ko te nekehanga o ngā ngota ngota mai i tētahi pūtau ki tētahi atu, ko te kawe tawhiti ko te nekehanga o ngā matū i roto i te tipu mā roto i ngā kiko toto.
1. Te Kawe i Tawhiti:
– Xylem: Kawe i te wai me ngā kohuke mai i ngā pakiaka ki ngā rau.
– Phloem: Ka kawe i ngā hua o te photosynthesis mai i ngā rau ki ngā wāhanga katoa o te tipu.
2. Te Kawe i waenga i ngā Pūtau:
– Kei roto i ēnei tukanga te horapa, te osmosis, me te whakamahinga o ngā pūmua kawe i roto i ngā kiriuhi pūtau.
Ngā Pātai Tauira me te Kōrero
Pātai 1: Tikanga Kawe Wai
Pātai:
Whakamāramahia te tukanga o te kawe i te wai mai i ngā pakiaka ki ngā rau i roto i ngā tipu.
Kōrero:
Ko te kawe wai mai i ngā pakiaka ki ngā rau ka puta tuatahi mā roto i te kiko xylem. He maha ngā wāhanga nui o tēnei tukanga:
1. Te mimiti wai e ngā pakiaka:
Ka mimiti te pakiaka i te wai mai i te oneone mā te osmosis. He nui te kukū o ngā katote i roto i te rohe huruhuru pakiaka, e kukume ana i te wai ki roto i ngā pūtau pakiaka.
2. Te urunga ki roto i te Xylem:
Mai i te kiri o te pakiaka, ka neke te wai ki roto i te pakiaka tae noa ki te xylem. Ka puta pea tēnei mā te ara symplastic (mā roto i te cytoplasm o te pūtau) mā te ara apoplastic rānei (mā roto i ngā pakitara pūtau).
3. Te Whakapūngao me te Kume Hononga:
Mā te mimiti o te wai mai i ngā rau ka puta he kaha kukume e kiia nei ko te kume whakawhiti wai, ko te kaha kume whakawhiti wai rānei. Mā tēnei ka neke ake ngā ngota wai i roto i te kakau nā te piri tahi me te piri ki ngā pakitara xylem.
4. Te tohatoha i roto i ngā rau:
Kia tae atu ki ngā rau, ka rere te wai ki ngā pūtau rau, ka whakamahia mō te whakaahua ora, ka mimiti rānei ki te āhuarangi mā roto i ngā stomata.
Pātai 2: Te Tūranga o te Phloem i roto i te Kawe Huka
Pātai:
He pēhea te mahi a te phloem i roto i te kawe i ngā hua o te photosynthesis ki ngā wāhanga katoa o te tipu?
Kōrero:
Ko te phloem te kawenga mō te kawe i te sucrose me ētahi atu matūkai mai i ngā rau ki ētahi atu wāhanga o te tipu, he tukanga e mōhiotia ana ko te translocation. Ko te tikanga e whakamārama ana i tēnei tukanga ko te ariā rere-pēhanga:
1. Te uta i roto i te Pūtake:
Ka hurihia hei sucrose e ngā pūtau rau e whakaputa ana i te hukahuka i te wā o te whakaahua-whakawhiti. Kātahi ka utaina te sucrose ki roto i ngā pūtau phloem mā roto i tētahi tikanga hohe, e hiahia ana ki te pūngao ATP.
2. Te Waihanga i ngā Rōnaki Pēhanga:
Ka whakaitihia te pūmanawa wai i roto i te phloem e te kohikohinga o te sucrose, ka kukumehia te wai mai i te xylem mā te osmosis. Ka whakanuia e tēnei rerenga wai te pēhanga turgor i roto i ngā wāhanga tātari phloem.
3. Te Nekehanga i roto i ngā Ngongo Phloem:
Mā te pēhanga turgor teitei i te wāhi pūtake ka rere te wairewa sucrose ki ngā wāhanga o te tipu e kiia nei ko ngā totohu, arā, ngā wāhi e whakamahia ana, e rongoatia ana rānei te pūngao, pērā i ngā pakiaka, i ngā hua rānei.
4. Te tango i te utanga i roto i te totohu:
Ka haria kaha, ka haria rānei te hukahuka mai i te phloem ki ngā pūtau totohu. Mā te hekenga o te kukū hukahuka ka hoki te wai ki te xylem mā te osmosis, ka whakaitihia te pēhanga i roto i te phloem.
Pātai 3: Te Horapa me te Osmosis i roto i te Kawe Pūtau
Pātai:
Homai he tauira mō te whai wāhi a te horapa me te osmosis ki te kawe pūtau i roto i ngā tipu.
Kōrero:
1. Te horapa:
Ko te horapa te nekehanga o ngā ngota mai i tētahi wāhi he nui te kukū ki tētahi wāhi he iti te kukū. I roto i ngā tipu, ka kitea te horapa i te wā o te whakawhiti hau i roto i ngā rau, me te hauhā waro e tomo ana, me te hāora e puta ana mā roto i ngā stomata.
2. Te Osmosis:
Ko te osmosis te horapa o te wai mā roto i tētahi kiriuhi haurua-whakauru. Ka puta tēnei āhuatanga ina neke te wai ki roto i ngā pūtau pakiaka, e whai ana i te pikinga pēhanga osmotic i hangaia e ngā otinga matūkai oneone kua rewa.
3. Tauira whakamahinga i roto i ngā pūtau:
– Ka mimitihia te wai e ngā pūtau pakiaka mai i te oneone mā te osmosis.
– Ka whakamahia e ngā pūtau tiaki e karapoti ana i te stomata te osmosis hei whakatuwhera me te kati, hei whakahaere i te whakawhiti hau me te ngaronga wai mā te whakapūhau.
Whakamutunga
He mea nui te mārama ki ngā tikanga kawe i roto i ngā tipu hei tūhura i te oranga me te whanaketanga o ngā tipu. Ko ngā pātai i runga ake nei he tauira hei whakamātautau i te māramatanga ki ngā tukanga o te xylem me te phloem i roto i te kawe wai me ngā matūkai, tae atu ki te whakamahinga o ngā mātāpono taketake o te horapa me te osmosis i roto i te horopaki o te koiora tipu. Mā te tūhura i ngā pātai me ngā kōrerorero maha, e tūmanakohia ana ka pai ake te māramatanga o ngā ākonga ki te ariā o te kawe i roto i ngā tipu me te pānga o ngā mātāpono koiora taketake ki te oranga o ia rā o ngā tipu.
