為什麼我們在這個實驗裏要把葉片的葉綠素除去,才進行碘液試驗?

✔ 最佳答案
葉綠素會同光進行光合作用產生"電"粉

"電"粉會令碘液由棕色變成藍色

that's because cholophyll has color. thus, may affect the person to see the color change clearly. besides, by removing the cholophyll then put the decolorised leave on the white tile, it'll enable one to see the color change much more easily.

如果不先清除葉緑素, 加了碘液後的澱粉的顏色改變, 便會被葉緑素遮蓋而看不清楚.
