The root system and the central vacuole.
Yes. I forget what the process is called, but water goes through the roots and leaves through the stomates (microscopic holes) in the leaf as water vapor.
On each stomata, there are guard cells. The guard cells control the amount of water released. Water escapes through the stomatas in the form of water vapor.
water vapor
(evaporation) water becomes vapor, (condensation)vapor is still vapor, (precipitation) vapor becomes water again...
when water vapor escapes from a leaf, it is called transpiration.
evapotranspiration
when water vapor escapes from a leaf, it is called transpiration.
Transpiration
I could see water vapor escaping from the boiling pot.
The process I think you're speaking of is transpiration. If you can physically see water droplets on the leaf you could also be witnessing guttation, though, this depends on whether you are viewing this during the day or night. If it is indeed guttation, not transpiration, you would be able to see what looks like water droplets on the leaf surface.
