Each stoma on the leaf's surface opens and closes to regulate the plant's water balance.
The stoma provides a pathway for gases to move in and out of the plant's tissues during photosynthesis.
Botanists study the structure of the stoma to understand how plants adapt to different climates.
The guard cells surrounding the stoma control its opening and closing in response to light and humidity.
