Guttation is the loss of water in the form of water droplets from hydathodes (small pores) on the leaf margin of a small herbacious plant. What is guttation? Guttation is the loss of water in the form ...

Hydathodes are specialised leaf structures that facilitate guttation, the exudation of xylem sap as droplets at leaf margins or surfaces under conditions of high root pressure and low transpiration.

Guttation: Water exuded from leaves. It appears as a single large drop pendant at the tip of a leaf or blade of foliage, and in grass it is often confused with dew. Weiss hospital, set to lose ...

Natural vascular plants leaves rely on differences in osmotic pressure, transpiration and guttation to produce tons of clean water, powered by sunlight. Inspired by this, we report a sunlight-driven ...
