Guttation is a process by which plants release excess water from leaves as droplets. A specialized organ known as a hydathode is used for this process so that plants can maintain optimum water balance. In this article, we will read about the demonstration, its mechanism, and demonstration , the role of hydathodes in guttation , the composition of water released during guttation , the difference between guttation and transpiration , and the importance of guttation. Guttation is a process that occurs in the case of vascular plants, in which excess water is removed from the leaf tips. Pores similar to stomata called hydathodes are present on the leaf tips that aid in this process.

Guttation is how plants expel excess water or nutrients through tiny openings on leaves and stems. Name — guttation Common name — crying plant, weeping leaves, teary plant, dewdrop Type — plant physiological process. This biological process enables plants to restore balance between their nutrient intake and needs. Guttation occurs when a plant oozes water and minerals out from perfectly healthy leaves , stems, and sometimes even flower petals. It takes place when roots of a plant absorb more water than the plant actually needs. Tiny, specialized cells on the surface of a leaf or stem are connected to veins and sap channels of the plant. This cluster of cells works as a nozzle. This process where excess pressure is released from inside the plant is called guttation. To understand why plants developed guttation as they evolved, it helps to brush up the following:. Hydathode nozzles are one of the biological tools plants use to regulate pressure inside them.

Hydathodes form natural openings but, unlike stomata, are open permanently and offer little resistance to the flow of fluid out of leaves. The cells of epithem are soft and made of loosely arranged thin-walled parenchyma cells and without chloroplast, and are involved in absorption and secretion. Internally, they are connected by tracheary endings to a large chamber with masses of thin-walled parenchymatous tissue surrounded by a sheath layer.

Suggest changes. Guttation becomes more important during the night when the plant continues to absorb water from the soil.

Guttation is the process of liquid exudation from hydathodes situated on the tip, along the margins and adaxial and abaxial surfaces of leaves. Hydathodes, also known as water stomata or water pores, unlike stomata, are always open representing the path of least resistance to the liquid outflow from them.
