Answer:
gaseous exchange i.e. intake of carbon dioxide and release of oxygen. The second is the process of transpiration in plants.
Air enters the plant through these openings. The carbon dioxide is used in photosynthesis. Some of the oxygen produced is used in respiration. Surplus oxygen exits through these same openings. Also, water vapor goes into the atmosphere through these pores in transpiration.
The pore is formed by a pair of cells known as guard cells. These adjust the size of the opening by opening or closing. To open a guard cell, protons (hydrogen ions, H+) are pumped into the guard cells. Water enters into them, the cells gets filled, and they open.
