想問問:photosynthesis的dark reaction 需唔需要light?
我知light reaction一定要light,dark reaction就有冇light都得,
但冇light reaction,何來dark reaction?咁dark reaction 係唔係要light?
仲有,dark reaction可以take place in the dark,但at night,唔係冇photosynthesis ga咩?唔係只有respiration ,冇photo ga咩?
hope大家可以help到我

✔ 最佳答案
photosynthesis的dark reaction 唔需要light但night係唔會有photosynthesis,只會有respiration
首先, light reaction係需要light
li樣我相信你已經清楚
咁o係light reaction就會produce hydrogen and oxygen
你知道dark reaction係要hydrogen嗎?
由於夜晚冇light reaction,所以冇hydrogen produce出黎...
所以即使dark reaction可以o係冇light之下進行
dark reaction o係night都唔會take place
因為冇hydrogen
總括黎講
dark reaction係唔need light
你講得o岩!
冇light reaction就唔會有dark reaction
所以photosynthesis就need light o勒!
明冇?

記住:night係唔會有photosynthesis,只會有respirationdaytime就會有photosynthesis and respirationbut the rate of photosynthesis is far more higher than that of respiration!^^

At night, there is photosynthesis taking place in plants as light is also present from moon and stars. But the rate of it would be slower.

at night有photosynthesis，只不過是rate of respiration 快過rate of photosynthesis, 搞清Concept ma!
