Answer»

The LEAVES of certain plants exhibit droplets of water along their MARGINS in the morning. This particularly happens in plants growing in warm humid CONDITIONS. A humid ENVIRONMENT hampers transpiration while the roots continue to absorb water from the soil. This builds up a BIG hydrostatic pressure within the plant and “forces out” the excess water directly from the tips of veins in the leaf. Special pore-bearing structures called hydathodes are present on the margins of the leaf to allow this exudation.
