2.54 Transpiration

5 Key points

1. transpiration will occur where H20 liquid change into Gas
2. This is created by the sunlight where light energy transfer to heat and absorb by the structure of the leaf
3. Water from the roots travel to the leaf by the osmosis
4. Heat from the sunlight causes the water to become a vapour where it is 100% humidity in leaf spaces
5. The phase change occured and the gas diffuses out of the leaf through the stomatl pore by the steep diffusion gradient and also to the lower humidity outside
