I-Cacti liqela elinomdla lezityalo ezikwaziyo ukuhlala zingapheleli nje kodwa zichume kwezinye zezona ndawo zinzima emhlabeni.Ngokuhlala ubukhulu becala kwiindawo eziyimiqwebedu kunye nebharhileyo, baye bavelisa uluhlu olunomtsalane lokuziqhelanisa nokuqinisekisa ukuphila kwabo.
Olunye uhlengahlengiso oluphawulekayo lwecacti kukukwazi kwabo ukugcina amanzi.Iziqu zazo ezishinyeneyo nezizinyama zisebenza njengemithombo yamanzi, nto leyo ezenza zikwazi ukumelana nexesha elide lembalela.Ezi ziqu ziyakwazi ukwanda kwaye zicutheke njengoko ukufumaneka kwamanzi kuncipha, nto leyo evumela ukuba i-cactus igcine amanzi amaninzi kangangoko ngexesha lemvula kwaye ilondoloze ukufuma ngexesha lembalela.Oku kuziqhelanisa akuncedi kuphela i-cacti ukuba iphile, kodwa iyakhula kwiindawo zokuhlala ezinqongopheleyo ngamanzi.
Ukusabela kubushushu obugqithisileyo bendawo yabo yokuhlala, i-cacti nayo iphuhlise iimpawu ezikhethekileyo zesakhiwo.Amagqabi awo angamagqabi aguquliweyo anceda ukukhusela isityalo ekukhanyeni okukhulu kwelanga kunye nokuthintela ukulahleka kwamanzi ngokuphuma komphunga.I-spines ikwanqanda i-herbivores ekutyeni i-cacti kuba ihlala ibukhali kwaye ihlaba.Ukongeza, enye i-cacti inomaleko wangaphandle we-waxy kwizikhondo zawo ezibizwa ngokuba yi-cuticle esebenza njengesithintelo esikhuselayo ekulahlekeni kwamanzi.
I-Cacti iphinde yavela kwiinkqubo zeengcambu ezikhethekileyo ukuze ziqhelane nendawo eyomileyo.Endaweni yeengcambu ezinde nezinamasebe eziqhele ukubonwa kwezinye izityalo, zineengcambu ezingenzulu nezibanzi ezizivumela ukuba zifunxe ngokukhawuleza nawaphi na amanzi akhoyo, kwanomlinganiselo omncinane.Ezi ngcambu nazo ziyakwazi ukufunxa ngokukhawuleza amanzi xa ekhona, ziqinisekisa ukufunyanwa kwamanzi ngokufanelekileyo.
Ukukwazi ukuvelisa kubalulekile ekusindeni kwayo nayiphi na into, kwaye i-cacti iye yavelisa iindlela ezizodwa zokuqinisekisa ukuzala okuphumelelayo kwiindawo zokuhlala ezinzima.Iicacti ezininzi, ezinje nge iconic saguaro cactus, zixhomekeke kwizinto ezihambisa ipoleni ezifana namalulwane, iintaka kunye nezinambuzane ukuze zisasazeke.Zivelisa iintyatyambo ezintle kunye nencindi ukuze zitsale ezi zinambuzane, ziqinisekisa ukudluliselwa kwepollen ukusuka kwisityalo ukuya kwisityalo.Ukongeza, i-cacti iphuhlise ukukwazi ukuvelisa i-asexually ngokusebenzisa iinkqubo ezinjengokwahlula kunye ne-branching.Obu buchule bubavumela ukuba benze ikholoni kwindawo ngokukhawuleza kwaye bandise amathuba abo okusinda kwiindawo ezinomngeni.
Lilonke, i-cacti iqhelene kakuhle neendawo ezisingqongileyo.Ukususela ekukwazini kwazo ukugcina amanzi ukuya kwinkqubo yazo ekhethekileyo yephotosynthetic, ezi zityalo zoyisa ngempumelelo ubushushu obugqithisileyo kunye nokungabikho kwamanzi.Ngeempawu zabo ezizodwa kunye nezicwangciso zephysiological, i-cacti bubungqina obuphilayo bendlela engaqhelekanga indalo eziqhelanisa ngayo kwaye iphumelele kwezona meko zinzima.
