Ngā Tauira Pātai e Matapaki ana i ngā Take e Pā Ana ki te Whakaahua-ā-Whare
He tukanga matū koiora nui te whakaahua-ā-ira e puta ana i roto i ngā tipu, i ngā rimurimu, me ētahi huakita, e hopukina ai te pūngao mārama, ka hurihia hei pūngao matū i roto i te āhua o te hukahuka. Hei mārama ki te mahi a te whakaahua-ā-ira me ngā āhuatanga e pā ana ki tēnei, he mea nui kia mōhio ngā ākonga me ngā ākonga ki ngā ariā taketake me te whakakoi i ō rātou pūkenga tātari mā te whakaharatau i ngā raruraru e pā ana. I roto i tēnei tuhinga, ka matapakihia e mātou ngā tauira pātai me ngā whakautu e pā ana ki ngā āhuatanga e pā ana ki te whakaahua-ā-ira.
Ngā Take e Pā Ana ki te Whakaahua-ā-Whāorite
I mua i te urunga atu ki ngā tauira pātai, me titiro tātou ki ētahi o ngā āhuatanga matua e awe ana i te tukanga o te photosynthesis:
1. Mārama: He nui te pānga o te kaha, te kounga, me te roa o te pānga o te mārama ki te tere o te whakapūngao. Ko te mārama te pūtake pūngao matua.
2. Te Kukū o te Hauhā Waro (CO2): Ko te CO2 te rauemi mata mō te whakaahua-ā-ira. Mā te whakanui ake i te kukū o te CO2 i roto i ētahi rohe ka taea te whakanui ake i te tere o te whakaahua-ā-ira.
3. Mahana: Ka pāngia te hanga whakaahua e te pāmahana o te taiao nā te mea he awhe pāmahana tino pai kei ngā whākōkī e whai wāhi ana ki tēnei tukanga.
4. Te Wātea o te Wai: Ko te wai tētahi o ngā rauemi mata mō te whakaahua-maimoa, ā, he mea nui hoki mō te pupuri i te hanganga o ngā pūtau tipu. Ka taea e te korenga o te wai te whakaroa, te aukati rānei i te whakaahua-maimoa.
5. Korowaira: Ko te nui me te kounga o te korowaira i roto i ngā rau e whakatau ana i te kaha o ngā tipu ki te hopu i te māramatanga mō te whakaahua-whakawhiti.
Tauira Pātai 1: Te Pānga o te Kaha o te Mārama
Pātai:
Ka whakanohoia he tipu ki roto i te whare me te kaha o te māramatanga rerekē puta noa i te rā. Ina iti te kaha o te māramatanga, ka heke te tere o te whakaahua. Whakamāramahia he aha tēnei ka puta, me pēhea hoki te urutau ā-tinana o te tipu ki ngā āhuatanga māramatanga iti.
Whakautu:
He rite tonu te tere o te whakapūtanga ki te kaha o te mārama tae noa ki tētahi wāhi. I ngā kaha iti o te mārama, ka heke te maha o ngā photon e wātea ana hei akiaki i te whakapūtanga, ka heke te tere. Ka taea e ngā tipu te urutau mā te whakanui ake i te nui o te chlorophyll, te whakarerekē rānei i te aronga o ō rātou rau hei hopu ake i te mārama. Ko ētahi atu tukanga whakaū ko te whakanui ake i te horahanga o te mata o te rau, te whakahaere rānei i te katinga o te stomatal hei pupuri i te taurite i waenga i te whakauru CO2 me te ngaronga wai.
Tauira Pātai 2: Te Pānga o te Kukū o te Hauhā Waro
Pātai:
I roto i tētahi whakamātautau, i whakanohoia ngā tipu kohua e rua ki roto i ngā rūma rerekē e rua. Ko te kukū CO2 o te Rūma A he 0.03%, ko te kukū CO2 o te Rūma B he 0.06%. Whakatauritea ngā tere o te whakapūngao i roto i ngā rūma e rua, ā, whakamāramahia te take.
Whakautu:
Ka tere ake te hanga whakaahua i roto i te rūma B ki te rūma A nā te mea he nui ake te kukū o te CO2 i roto i te rūma B. Ko te hauhā waro tētahi o ngā rauemi matua o te tauhohenga hanga whakaahua, nō reira mā te whakanui ake i te kukū o te CO2 ka taea te whakanui ake i te tere o te hanga whakaahua kia tae rā anō ki te taumata kukū. I te taumata kukū, kāore te tere e piki ake ahakoa te whakanui ake i te kukū o te CO2.
Tauira Pātai 3: Te Pānga o te Pāmahana
Pātai:
Ka nekehia ohoreretia tētahi tipu e noho ana i te āhuarangi mahana ki tētahi taiao he nui ake te pāmahana i tōna pāmahana tino pai. Matapakihia te pānga o ngā pāmahana kāore i te tika ki te tukanga whakaputanga raraunga, me pēhea hoki te urutau o te tipu ki tēnei āhuatanga.
Whakautu:
Ka pā te pāmahana ki te mahi a ngā whākōkī i roto i te whakaahua-whakawhiti. I ngā pāmahana e tino teitei ake ana i te awhe tino pai, ka taea e ngā whākōkī te whakarerekē i te āhua, ka aukati i ngā tauhohenga matū e tika ana mō te whakaahua-whakawhiti. Hei tāpiri, ka taea e ngā pāmahana teitei te whakararu i te ahotea wera, ka piki ake te tere o te manawa i tua atu i te whakaahua-whakawhiti, ka pau te kaha me ngā rauemi o te tipu. Ka taea e ngā tipu te urutau mā te whakanui ake i te whakaputanga o ngā pūmua ahotea-wera, te whakarerekē i te mahi a te stomata hei whakaiti i te ngaronga wai, mā te whakaōrite hanganga rānei, pērā i te whakarerekē i te aronga rau hei whakaiti i te mimiti wera.
Tauira Pātai 4: Te Pānga o te Wai
Pātai:
I te wā maroke, ka kōwhai te nuinga o ngā rau tipu, ka hinga. He aha te pānga o te kore wai ki te tukanga whakaputanga o te rauropi, ā, he aha ngā tikanga e whakamahia ana e ngā tipu hei oranga mō ngā āhuatanga maroke?
Whakautu:
Ka kati ngā stomata i te korenga o te wai, ka whakaiti i te mimiti, ka whakaiti i te kohi CO2, ā, ka whakaiti i te tere o te photosynthesis. Tērā pea ka heke te hanga chlorophyll o ngā tipu, ka huri te kōwhai o ngā rau. Hei whakatau i ngā āhuatanga maroke, ka taea e ngā tipu te whakanui ake i te whai huatanga o te whakamahinga wai me te whakawhanake i ngā pakiaka hohonu ake kia tae atu ki ngā puna wai o raro whenua. Tērā pea ka uru atu ētahi tipu ki te wā moe hei whakaiti i ā rātou hiahia pākia.
Whakamutunga
He mea nui te mārama ki ngā āhuatanga e pā ana ki te photosynthesis i roto i te koiora me te ahuwhenua. Kei roto i ēnei āhuatanga ko te kaha o te mārama, te kukū o te CO2, te pāmahana, te wātea o te wai, me te nui o te chlorophyll. Mā te whakaoti i ngā mahi i runga ake nei, ka taea e ngā ākonga te mārama ki te whai wāhi me te taunekeneke o ia āhuatanga ki te whakatau i te whai huatanga o te photosynthesis i roto i ngā tipu. He mea whai hua tēnei ehara i te mea i roto i ngā horopaki mātauranga anake engari i roto hoki i ngā mahi ahuwhenua hei whakapiki i te hua o ngā hua mā te whakahaere taiao pai ake.
