1.Ibimera bimurika ni ugusimbuza urumuri rw'izuba hamwe n’ibidukikije byoroheje kugira ngo ibimera bikure neza.Hatariho urumuri, ibimera ntibishobora gukura.Mu bimera, urumuri rukora nkikimenyetso cyibidukikije kugirango bigabanye urukurikirane rwikura ryimyitwarire nimyitwarire yiterambere, harimo kumera kwimbuto, kubaka morphologie, indabyo hamwe na synthesis ya metabolite ya kabiri.Muri iki gihe, ibimera bya fotosintezeza bikurura urumuri rwizuba, bigahinduka isukari, kubibika, no kubikoresha kugirango bikure.

2.Mu "kumenyekanisha" no "guhitamo" k'umucyo, ubuyobozi buyobora burashobora gutangwa muguhinga urumuri rwibihingwa.Amatara yo gukura yibihingwa arashobora gutegurwa neza kuri buri gihingwa cyangwa buri gihe cyiterambere, kandi imiterere yumucyo wibihingwa byakozwe neza irashobora guhinga ibihingwa neza kandi bigatanga urumuri nifumbire bihagije kugirango bikure.

3.Ibimera bikura ntibishobora gusa kuzamura igipimo cyogukoresha ingufu zumucyo gusa, kongera umusaruro, ariko kandi binonosora imiterere nibara ryibimera, ibice byimbere, nibindi. Byakoreshejwe cyane mubukoko bwica udukoko no mubindi bice.Amatara akura neza yibihingwa, afatanije ningamba zubwenge kandi zinoze zo kugenzura urumuri, bituma imikurire y’ibihingwa itagabanywa n’imiterere y’umucyo karemano, ifite akamaro kanini mu kuzamura umusaruro w’ubuhinzi no kurinda umutekano w’ibikomoka ku buhinzi.

Muri make, gukura amatara bifasha cyane gukura no gutanga umusaruro kuruta urumuri rusanzwe.
