Answer 2

• Certain number of specialised cells are named after the function they perform like protective cells, guard cells, storage cells etc.
• Guard cells are called so as they guard or protect the opening through which gaseous exchanges take place.
• They also control and time the opening and closing depending on pressure, availability and temperature.
• Thus guard cells are nothing more than specialised cells that guard and control gaseous openings.
