Ibonakala ngesakhiwo se-stem esingenalutho esizungezwe izicubu ze-vascular annular
Impendulo ithi: izitshalo ze-vascular.
Izitshalo ze-Vascular zinesiqu esingenalutho esizungezwe izicubu ze-annular vascular, isici esiyingqayizivele kulolu hlobo lwesitshalo.
Lesi sicubu se-vascular sakhiwe i-xylem namagxolo, afaka isandla ekusekeleni isiqu futhi asinikeze izakhi namanzi.
Izitshalo zemithambo zihlanganiswe eqenjini elibanzi lezinhlobo zezitshalo futhi zibalulekile empilweni yomuntu neyezilwane.
Jabulela ubuhle bezitshalo zemithambo futhi ubambe iqhaza ekulondolozeni indawo yazo yemvelo, njengoba zidlala indima ebalulekile ekugcineni ibhalansi yemvelo yeplanethi.
