Ko te kiko whakato matua: he whakaahuatanga katoa o

Papanga - he hanganga arā, o te plurality o ngā pūtau rite e whai mahi noa. kararehe katoa multicellular me otaota (hāunga pükohu) ngā o ngā momo rerekē o te kiko.

He aha e te papanga?

I roto i te kopa kararehe e wehea ki wha momo:

• epithelial;
• uaua;
• tūhono;
• kiko tailiili.

Katoa o ratou, ki te kahore hoki te io, wehea i roto i te tahuri ki ngā momo. Ko te kupu, ko te epithelium taea e pūtoru, flat, porotakaroa, ciliated me tairongo. Kei te wehea Uaua kikokiko ki striated, cardiac me te maheni. Kei o ngako tūhonohono, kaiota te matotoru, te muka wewete, reticular, wheua, me te ngohe, te toto me te te tīpona te Rōpū.

te kopa Plant Ko enei momo:

• mātauranga;
• conductive;
• paninga;
• kiko aunoa;
• puha (secretory);
• kiko e whāriki ana (parenchyma).

Kua wehewehea katoa o ratou ki iti-rōpū. Na, hoki te kopa mātauranga e kāpeka, intercalary, taha me te marutanga. Conductive wehea ki te kōtai me kōkai. Hipoki papanga ngā toru ngā momo: te kiriwaho, puru, me te Cork. Kei te wehea Manual ki collenchyma me sclerenchyma. Kei te wehea kiko Secretory ki momo. He kiko te tipu nui, rite etahi katoa, ko o te maha momo. Kia titiro tatou ratou i roto i ngā kōrero.

He aha te mea te kiko tipu matua?

E wha o ona momo. Ko te kupu, ko te papanga matua ko:

• aquifer;
• whāhauhau;
• whakawhenumi;
• kararehe ki runga.

E ratou he hanganga rite, engari i etahi rerekētanga i ia atu. Ko ahua rerekē hoki te mahi matua o enei momo e whā o te kiko.

Ko te hanganga o te papanga: he tirohanga whānui

hanga te papanga taketake o te katoa ngā momo e wha te ake o ngā pūtau e noho ki taiepa angiangi. Kei te pera ka karanga papanga o tenei momo no te mea ko ratou te pūtake o nga whekau faufaa katoa. Na kia titiro a ki te mahi, me te hanganga o te papanga taketake o ia momo takitahi i roto i te taipitopito atu.

Water-whanau kiko: hanganga me te mahi

hangaia te papanga matua o tenei momo te o ngā pūtau nui i taiepa kikokore. I roto i nga vacuoles o ngā pūtau o te kikokiko mucous kei te taonga motuhake, hoahoa nei ki te pupuri i makuku.

takoto mahi aquifer papanga i roto i te meka e pupuru ana i te reira makuku.

He wai-whanau parenchyma i roto i te tātā me rau o ngā tipu pērā i cacti, agave, aroe, me ētahi atu, e tupu i roto i climates maroke. Nā ki te maha nui o taua kiko tipu taea te ake i runga i te wai i roto i te take o te ua e kore e waiho roa.

Āhuatanga whāhauhau parenchyma

He pūtau kiko e whāriki ana o nga momo i te tawhiti i ia atu. I roto i waenganui i te hunga i te wāhi intercellular i roto i nei rongoa rangi te.

Ko te mahi o te parenchyma ko e whakarato ana te reira i te pūtau o te tahi atu te kopa o te tipu ki te hauhā me te hāora.

He he he kiko taua i roto i te tinana te nuinga i roto i te repo, me ngā tipu rōwai. I roto i te whenua ko reira onge.

parenchyma, kaaore e: hanganga me te mahi

Kei reira o te pūtau angiangi-taiepa reo-rahi.

Roto te kiko Kawanatanga pūtau i roto i ngā tau nui e chloroplasts - te organelles kawenga mō te ahotakakame.

Ēnei organelles E rua kiriuhi. Roto te thylakoids pūkano tipumata e - peke discoid o whākōkī i roto i a ratou. E kohia ana ratou i roto i puranga - grana. Tata tuatihia e te lamellar - hanganga elongated rite ki te thylakoids. I tua atu, chloroplasts he ribosome inclusions māngaro tika ki ariā o te pūmua, DNA me te pae RNA.

Ko te tukanga o te ahotakakame - te whakaputa matū pararopi i pararopi e whākōkī me te pūngao kōmaru - puta i roto i thylakoids. huaina te whākōkī matua i whakarato enei tauhohe matū te chlorophyll. Tenei taonga he matomato (whakawhetai ki a ia nga rau, me te kakau o ngā tipu i tenei tae).

Na, ko te mahi matua o tenei ahua o te kikokiko - ahotakakame whakahuatia i runga ake, me te utu hau.

Ko te nuinga o whakawhanakehia i roto i te rau whakawhenumi kiko, me te runga kakau o ngā tipu herbaceous. Ko reira i roto i te matomato hua ano hoki reira. e kore he whakawhenumi kikokiko i runga i te mata o te rau me te kakau, me te kiri tiaki mārama.

parenchyma Āhuatanga rokiroki

E huru no te pūtau o tenei kikokiko rite te rahi reo. Ko o ratou taiepa nuinga kikokore, engari kia thickened ai.

Taumahi parenchyma rokiroki - rokiroki o ngā matūkai. Ka rite ki taua, i nuinga o te wā, te kaimahi te reira rite māngaro, inulin, me ētahi atu warowaihā, a ētahi wā - pūmua, waikawa amino me te ngako.

Ko reira te papanga o tenei momo i roto i embryos o purapura o ngā tipu ā-tau, me te i roto i te endosperm. I roto i te e tōkena otaota te koiora, rakau iti, puawai, me nga rakau papanga kia i nga topuku, kōpura, pakiaka, me te rite i roto i te matua o te kakau.

mutunga

Ko te papanga matua - te nui tino i roto i te tinana o te tipu, mai te mea te reira i te pūtake o nga whekau katoa. Papanga o tenei momo whakarato nga tukanga faufaa katoa, tae atu ahotakakame me te utu hau. Ano, te kiko taketake kawenga mō te hanga i te rārangi o ngā matū waro (te nui tino he māngaro) i roto i te otaota ratou, engari ano i roto i o ratou purapura. Ka taea te waiho e tua matūkai matū i roto i te parenchyma rangi me te wai. Whāhauhau me te kopa wai-amo i kore katoa otaota. Ko te hakari tuatahi anake i roto i te koraha, me te tuarua - i roto i ngā momo repo.
