Kule mihla, kunokwenzeka ukuba uhambe kwisixeko sakho, edolophini okanye kumasipala kwaye wonwabele imithi ephezulu, ebonelela ngomthunzi ngobukhulu bayo obukhulu kunye namagqabi amakhulu aluhlaza.
Lixesha lokukhula okukhulu kwezityalo, ezisebenzisa amandla elanga kwaye zikhule ngokukhawuleza okukhulu. Kodwa lo mbono uqala ukutshintsha xa ekwindla lisondela kwimithi emininzi kunye nezityalo ezinqabileyo ziqala ukulahla umbala, amagqabi ayo ajike abe mdaka okanye tyheli ishiya ngasemva eluhlaza kwayo.
Kwenzekani?
Yintoni ebangela ukuba luhlaza
El umbala oluhlaza wezityalo ayenzeki ngokuthanda kwendalo kodwa kungenxa ye I-chlorophyll yokwakha, i-pigment efumaneka ngaphakathi kwii-chloroplast, okt i-organelles ezikhoyo kwiiseli zezityalo kwaye zinoxanduva lwe-photosynthesis.
Ukuze isityalo sikwazi ukuvelisa iklorophyll sidinga ukukhanya kwelanga kunye namaqondo obushushu afudumeleyo yiyo loo nto ngexesha lentwasahlobo nasehlotyeni imveliso ininzi kwaye uluhlaza lwamagqabi lukhulu kakhulu.
Njengoko iintsuku ziba mfutshane kwaye Ukukhanya kwelanga kunciphisa imveliso yombala kuyehla kwaye amagqabi aqala ukuphulukana nombala wawo. Oku kuhambelana nokufika kwekwindla.
Nangona izityalo zinemibala emininzi, ichlorophyll opaque kwezinye kodwa kwangaxeshanye yeyona ihlamba ngokukhawuleza xa isityalo sifumana iiyure ezimbalwa zokukhanya kwelanga. Kungenxa yoko le nto amagqabi eqala ukuphulukana nombala oluhlaza ekwindla kwaye ezinye ii-pigment ezazigqunywe luhlaza ziyavela, iithoni eziqhelekileyo ezimthubi kunye neeorenji zamagqabi ekwindla.
Ezahlukeneyo zombala
Njengokuba besesitshilo, izityalo aziqokeleli i-pigment eluhlaza kuphela kodwa zininzi zazo kwaye le amalgam inokubonwa ngemibala eyahlukeneyo enokuba nomthi okanye isityalo. Oku kwenzeka kuba izityalo ziqokelela ii-pigment kumagqabi azo ukuze zifunxe ukukhanya ngelixa zivelisa ukuzikhusela kwimitha yelanga.
