How do the guard cells regulate opening and closing of stomatal pores?

AcademicBiologyNCERTClass 10

The guard cells regulate the opening and closing of stomatal pores by the osmosis process.
When water flows into the guard cells, they swell up and the curved surface causes the stomata to open. When the guard cells lose water, they shrink and become flaccid and straight thus closing the stomata.
