Photosynthesis stops in the dark ...
但係點解佢會stop 呀?!
乜 photosynthesis 唔係 include 埋dark reaction 咩?!
so what is the difference and relationship between them ???

✔ 最佳答案
你要知道光合作用除左 dark reaction 之外仲有 light reaction架 bo ,再且好緊要。因為要光比能量 break down water molecules,咁先會有 hydrogen 同 oxygen,所以如果無光就做唔到 light reaction,hydrogen 係用黎做 dark reaction ge 材料,如果無 hydrogen ,咁都唔可以同二氧化炭 react 出炭水化合物,即係未做 light reaction 係做唔到 dark reaction ~ 明無?

light reaction : 要光比能量
dark reaction: 唔駛光比能量,但要有 hydrogen 同 co2
