transpiration算唔算係active transport ge一種...?

唔算.
因為呢個process 純係物理力量推動. 係就算植物死左, 都可以繼續有transpiration. 完全用不著植物既能量 [如ATP]

回三樓的 [香港早晨] 君:

水份由樹葉散出空氣, 係蒸發, 唔係osmosis.

Transpiration is Osmosis but not Active transport.

In Active Transport,Energy is required but Transpiration doesn't require any energy. Water flows from higher water potential(Tree/soil) to lower water potential(air) but not from lower water potential to higher potential. Hence, Transpiration is not Active Transport.

But in the process, the water flows from higher water potential(Tree/soil) to lower water potential(air) without energy, so it is a kind of Osmosis.

This is one of the common misconception of Plants.

我覺得唔算- -
因為你蒸發係分子轉態
同分子既淨移冇關
所以應該唔係
