Guard Cells: Surrounding each stoma are two specialized cells called guard cells. The opening and closing of these guard cells control the size of the stomatal aperture, regulating the rate of transpiration.
Guard cells surround stomata, regulating transpiration rate by controlling the stomatal aperture size.
