Izilwanyana zinegazi elibaleka emithanjeni yethu, ulwelo olunamanzi, iiseli ezibomvu nezimhlophe zegazi, kunye neeplatelets. Inoxanduva lokuhambisa ioksijini kuwo onke amalungu omzimba wethu. Kodwa izityalo zikwanalo "igazi" lazo, umahluko kukuba licace gca kwaye linelinye igama: incindi.
Ngombulelo kuyo, zonke izityalo zingaphila, zikhule kwaye zikhusele, ngendlela ethile, kwizitshabalalisi ezibachaphazelayo.
Yintoni incindi?
Ngulwelo oluhanjiswa zizicubu zokuqhuba zezityalo (xylem okanye phloem). Zimbini iintlobo ezahlukileyo:
- Iyonke: ithuthwa ukusuka ezingcanjini isiya emagqabini ziinqanawa zomthi ezenza i-xylem. Inamanzi ikakhulu kunye nezimbiwa ezanyibilika kuyo kunye nabalawuli bokukhula.
- Yandisiwe: ithuthwa ukusuka kumagqabi kunye neziqu ziye kwingcambu ziinqanawa zaseLiberia ezenza i-phloem. Inamanzi, iswekile, iiphytoregulators kunye neeminerali ezichithakeleyo.
Njengoko ubona, kubaluleke kakhulu kuzo zonke izityalo, kuba enkosi kuyo banokondla kwaye bakhule. Ukuba abenzanga, ngekhe babekhona.
Ukubaluleka kwencindi yegadi okanye yomfama
Ukwazi ukuba yintoni kanye kanye kubaluleke kakhulu kuthi sonke abasebenza okanye abakhathalela izityalo, ukusukela ezi zinto ziphilayo zivelisa ngakumbi ngeenyanga ezishushu kulapho ke banenqanaba lokukhula okuphezulu.
Ngesi sizathu, akufuneki ithenwe ehlotyeni, kuba ukwenza njalo kungaphulukana nentsalela eninzi kwaye kunganzima kubo ukuphola. Ukongeza, xa kunokwenzeka ukuba kubalulekile ukubeka uncamathiselo ukupholisa ukutywina amanxeba, ngakumbi ukuba yi-bonsai okanye imithi, ukunciphisa umngcipheko wosulelo.
Zithini izityalo zencindi?
Okokugqibela, kusenokwenzeka ukuba ukhe weva okanye weva ngezityalo zentsalela. Yintoni esi sityalo? Sisityalo nje esiqhelekileyo esimalunga nonyaka ubudala.
Ngaba uyifumene inomdla?
Molo, ibiluncedo kakhulu kwaye ibindifundisa ukusukela oko ndafunda uJohn 15 malunga nento uYesu athetha ngayo ngoBomi bokwenyani kwaye ndakwazi ukukuqonda ngokucacileyo ngakumbi ukufundwa endimbulisa ngothando ndinqwenela iintsikelelo
