Each pair of guard cells and the regulated pore they enclose, known as a stoma or stomate, provides a conduit for atmospheric photosynthetic gas exchange (CO2 uptake and O2 release) and transpirational release of water (H2O) in terrestrial plants, in addition to defense against pathogenic invasion.

Answer:
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.
