The correct answer is: gaseous exchange.
Lenticels are the areas in the bark which are filled with loosely arranged cells called complementary cells. The loss of water through lenticels is negligible (about $0.1 \%$ ) in comparison to the total water loss from the plant.

Both lenticular and cuticular gaseous exchange can take place continuously, both during the day and night, as there is no mechanism to stop or reduce it.
