Tips of leaves in grasses and common garden plants show water drops in early morning hours. This water accumulation is obtained from

The accumulation of water droplets on the tips and margins of leaves in grasses and garden plants during early morning hours is a phenomenon known as guttation [t1][t6]. Unlike dew, which is atmospheric moisture condensing on cool surfaces [c2][c3], guttation is the exudation of liquid water from the plant's internal vascular system [t2][t4]. This process occurs when root pressure is high and the rate of transpiration is low, typically at night or in high humidity [c1][t3]. The water is forced out through specialized permanent pores called hydathodes, also known as 'water stomata' or 'water pores,' which are located at the ends of leaf veins [t1][t2][t8]. While regular stomata facilitate the loss of water vapor through transpiration, hydathodes allow for the release of liquid xylem sap to maintain the plant's internal water balance [t4][t6].
