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. It occurs during the night when all the water is retained within the plant and gets excreted out due to high root pressure. It looks similar to transpiration, but the major difference lies in the fact that transpiration occurs during the daytime through stomata.

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. Ultrastructurally, the epithem cells have a dense cytoplasm, numerous mitochondria, an extensive endoplasmic reticulum system, many small Golgi-derived vesicles, numerous peroxisomes, and are interconnected by abundant plasmodesmata. Functionally, there are two types of hydathodes, namely, epidermal ones that actively exude fluid, and epithemal hydathodes that passively exude fluid. Natural guttation is often observed during early morning or late hours of the day. However, it can also be induced as desired in intact or excised plants under pneumatic pressure. Earlier notions regarding harmful effects on plants of guttation have now been addressed by botanical and physiological research discoveries regarding the basic and practical utility of guttation. This knowledge could lead to new health care applications on the one hand and ease global food-security concerns on the other.

Guttation diagram

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.

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. Guttation fluids contain a variety of living and non-living ingredients.
