Factors impacting opening/closing of stomata

All Answers (3 Answers In All)

By Jennifer Answered 5 years ago

 According to me the opening and closing of stomata is merely controlled by light and the level of carbon dioxide.
 

By Vishal Answered 5 years ago

the opening and closing of stomata will depend on the environmental factors such as humidity. 
  When the humidity condition is optimal, stomata will open. When the level of humidity in the air surrounding 
  the plant leaves decrease because of increase in temperatures or due to windy conditions, 
  the amount of water vapour diffusing from the plant increases. Under such a scenario, plants must close their stomata and prevent excess water loss.

By Nirav Answered 5 years ago

 Stomata will open and close due to diffusion as well. Under hot or dry conditions, when plants lose water due to evaporation, 
  stomata will be closed in order to prevent dehydration. The guard cells will pump potassium ions out of the guard cells. 
  When conditions change the stomata will open. The potassium ions will be pumped back into the guard cells.
