Kungenzeka yini ukuba ukhule ube banana ngaphandle phloem?

Donsa ophuzi banana ikhasi, futhi uyozizwa njengoba yena ngobumnene ihamba thwi kanye umbungu. Ngezinye kubhanana selivuthiwe ehlukanisa kalula kakhulu, uye wabonisa ukuvuthwa kuso kancane - iyinkimbinkimbi kakhulu kunalokho. Nokho, noma kunjalo, wayengasoze kudingeka.

Kodwa kukhona ecasulayo emithanjeni elimhlophe zikabhanana noma uma ukhuluma ngokuya yemvelo, 'izinyanda phloem'. igama mnandi kakhulu, akunjalo?

Uyini phloem

Uma kubonakala sengathi igama elithi "phloem" Uyazi, cishe kungenxa yokuthi i-zesikole enikeziwe ulwazi phloem futhi xylem. Le migomo ezimbili zichaza izicubu eziyinkimbinkimbi okuyinto athuthe izakhi zomzimba namanzi ngu simila. Ziyakwazi adingekayo ukuze ekukhuleni kwesitshalo nezithelo zaso.

Eqinisweni, lezi amayunithi wezinhlamvu ezithambile kwesabeka ukusabalalisa izakhi benyuka banana njengoba ikhula, okuvumela ukuba babe izithelo okumnandi, okuyinto abaningi kangaka uyakuthanda.

Abanye abantu babe kangaka zonda lezi izinyanda phloem ukuthi ngisho enikelwe kulesi sihloko wonke blogs. Kodwa ingabe abantu badinga ukwazi phloem ngaphezulu? Mhlawumbe kuphela yingcweni ubhanana wakwazi ukuchaza eziningi umehluko wemisindo nemiqondo yamagama.

Umbono uchwepheshe emkhakheni wesayensi yokuthakwa kwamakhemikhali

Ukuze uthole izimpendulo zemibuzo yakho, izintatheli I-Huffington Post waba nengxoxo Dr. Nicholas D. Gillittom, onguchwepheshe indawo ngokomzimba-chemistry wezinto ezingaphili. Uphinde iphini likamengameli ucwaningo kanye nomqondisi umsoco e-Institute of Dole Ukudla.

Ngakho, kungakhathaliseki ukuthi umsoco umehluko okhona phakathi izinyanda phloem futhi lonke Ingxenye edliwayo yale izithelo, njengomuntu banana?

Gillitt uthi: "Nakuba ososayensi phloem izinyanda ngokuqondile ihlolwe, kungenzeka ukuthi umsoco zizohluka. Lokhu kungenxa yokuthi ziklanyelwe ukwenza umsebenzi othize, futhi ngenxa yalokho kufanele isakhiwo ocacile esekela lo msebenzi. Nakanjani ukuthi bazoba laqanjwa elihambisana ukubunjwa evamile uginindela ezidliwayo zikabhanana. Libuye Kungenzeka ukuthi izinyanda phloem aqukethe inqwaba izinhlobo ezahlukene zemicu izingxenye zesakhiwo ezidingekile ukusebenza kwawo. Ngenxa yalokhu kungenzeka unezinye izakhi kwengoma. Noma kunjalo, zikhona ezinjalo nengcosana njengoba kuqhathaniswa lonke banana ukuthi uma ungadli wedwa, ngeke kuthinte jikelele umsoco isithelo. "

Ingabe kuphephile phloem?

Ingabe izinyanda phloem kuphephile? Lo mbuzo Gill wathi: "Ngokuvamile, zonke izithelo akuyona anobuthi. Abantu kudliwa apula ikhasi, amagonandoda nokunye. D., Futhi zazingaba izikhumba ubhanana, kuhlanganise izinyanda phloem, uma kubhekwa eyamukelekayo. Isayensi akanikezanga noma yiziphi ubufakazi obuqand 'ikhanda bokuthi zilimaza umzimba womuntu. Noma yimuphi fibre akunakubangelwa eziningi ukudla okunempilo. "

Guillén uphawula ukuthi ngokuvamile, asizange sithole noma iyiphi izikhalazo abalulekile kusuka kubathengi phezu izinyanda phloem. Kusukela umbono usosayensi, owachitha zokwelapha eziningana angamakhulukhulu izifundo, ukudla ukudla okuningi ubhanana besafunda, kungaba ngokuqiniseka ukuthi engakaze kubika isenzakalo esisodwa lapho ngabe isihloko wacabanga ukuthi izinyanda phloem kukhona ingozi yempilo.

Kungenzeka yini ukuthuthukisa banana ngaphandle phloem?

Lona umbuzo ethakazelisa kakhulu. Usosayensi uthi engase kungenzeka. Kodwa uma izinyanda phloem kudingeka i ukusatshalaliswa ezanele kwezakhi kulo lonke isitshalo, futhi akuzona ngempela eziphindaphindekayo ke lokho ngeke ukushayela ekukhuleni banana? Kusukela umbono abamele inkampani ukwandisa ukufinyelela ukudla okunempilo, kufanele athathe izinyathelo ezibalulekile kakhulu ukuba afeze ucwaningo ku zizalela izinhlobo isifo nemithi ubhanana esasizoba izakhi okusezingeni eliphezulu.
