Is transpiration part of the gas exchange system in plants, the water exchange system in plants, or both?

1 Answer

It is gas exchange system.


  1. Transpiration is gas exchange system in the plants. Mainly, water vapour is lost through this system and it cools down the plant body especially leaves. But some other gases such as oxygen, carbon dioxide etc., are also exchanged through it.
  2. There is a separate system of water loss in plants. Water loss is performed by the guttation through the hydathodes. Thank you
