Have you ever wondered why plants’ stomata, the tiny pores on the surface of leaves, open and close throughout the day? A new method developed in 2024 could finally shed light on this intriguing diurnal variation. With the ability to non-invasively measure stomatal conductance in real-time, researchers hope to uncover the underlying biological mechanisms driving this daily rhythm. What secrets could be revealed about how plants regulate water and gas exchange? Stay tuned as scientists delve into the fascinating world of plant physiology.
