You would not have any temp. control and start shivering and sweat and random times.
Hope this helps. :)
I think the first option is the answer.
Stomata are tiny pores present in the leaf that allows gas exchange and is where water vapour leaves plants and carbon dioxide enters. Special cells called guard cells present in the stomata, control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.
