Okubomvu, okusawolintshi, okuphuzi, ocher ... futhi okuluhlaza okwesibhakabhaka nokunsomi. Izinhlobonhlobo ze-chromatic ze imvelo ekwindla Isinikeza izithombe ezihlukile, ezinemibala ehlukahlukene kanye namathoni abonakala ekuhlanganisa nomdwebo noma isithombe esenziwe kabusha.
I-Los izihlahla ekwindla Banombala ophelele wombala emaqabungeni abo, ngaphambilini wawuluhlaza. Kepha… Kungani zishintsha umbala?
La imibala ehlukahlukene yemithi ekwindla ihlobene nesikhathi semisebe yelanga. Ukukhanya kwelanga kuyadingeka ukuze kutshalwe ukuze kukhiqizwe chlorophyll (ebanikeza umbala wabo oluhlaza okotshani). I-chlorophyll yona ibalulekile ku-photosynthesis, okungukuthi, inqubo i-chlorophyll esemaceleni eguqula ngayo amanzi ne-carbon dioxide ibe ukudla.
Ebusika, akukho ukukhanya kwelanga okwanele kwesihlahla ukugcina inqubo yaso i-photosynthesis igcwele, ngakho-ke isihlahla sihlala silele silinde intwasahlobo ukuthi ibuye futhi.
Ukukhiqizwa kwe-chlorophyll kuyehla noma kuyeke futhi kulapho ezinye izingulube zamaqabunga ezazikade zikhona, kepha zazifihlwe yi-chlorophyll eluhlaza okotshani, ziqala ukuvela.
Veza ifayela le- carotenoids, okudingekayo ukudlulisa amandla elanga, bese unikeza amaqabunga umbala ophuzi, ocher, nowolintshi. Ngaphandle kwalokho, i- i-anthocyanin, engekho kuzo zonke izinhlobo, ivikela izihlahla emisebeni ye-ultraviolet futhi yakha amathoni abomvu, aluhlaza okwesibhakabhaka nansomi.
Imibala yalesi sizini iba namandla kakhulu lapho izinsuku zasekwindla zibalele nobusuku bubanda kodwa izinga lokushisa aliweli ngaphansi kwezinga-qhwa. Uma lokhu kungenzeki, amaqabunga ayafa, ajike abe nsundu bese ewela phansi, lapho inqubo yokubola ibanika amabanga amasha ombala.
