A wall poster on gas exchange in plants tells its readers that plants breathe through their stomata. Why is calling that respiration wrong?

Объяснение

The word names the reaction that releases energy from sugar inside every living cell, while the movement of gases through the stomata of a leaf is gas exchange, which merely supplies that reaction and carries its waste away. Running the two ideas together makes it look as though a plant stops respiring whenever its pores are shut, which is not so.
