Nei miti yakawanda yakasvibira?
Zvirimwa zvakawanda zvine ruvara rwegirini nemhaka yokushandiswa kwechinhu chinogadzira ruvara rwegirini, chinonzi chlorophyll, mukuita photosynthesis. Photosynthesis muitiro uyo chirimwa chinoshandisa kushandisa simba racho rakachengetwa uye carbon dioxide nemvura muglucose. Basa rechlorophyll nderokupa simba iri nokupinza chiedza chezuva uye kushandura chiedza chezuva ichocho kuva simba. Chlorophyll yakasvibirira sezvo ichipinza mavara ose echiedza chena kunze kwegirini. Ruvara urwu runoratidzwa kumashure izvo zvinopa chlorophyll ruvara rwegirini.
