Hey there!
The function of guard cells is :
• They 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.
Hope it helps! :)
