HYDATHODE Meaning and
Definition
-
A hydathode is a specialized structure found in plants that is responsible for the secretion or excretion of water, usually in the form of droplets. It is commonly found in the leaf epidermis and functions as a water-translocating and water-excreting tissue. A hydathode consists of a small pore or opening, known as a water stomata, surrounded by specialized cells known as water cells. These water cells have the ability to actively transport water from the xylem vessels to the hydathode.
The main function of hydathodes is to remove excess water or to excrete water that cannot be reabsorbed by the plant. This process is known as guttation. Guttation occurs during periods of high humidity or when soil moisture levels are high, leading to an increase in root pressure. As a result, water is forced out of the plant through the hydathodes in the form of droplets or liquid. These droplets are often seen early in the morning on the tips or edges of leaves.
Hydathodes are vital for maintaining water balance within the plant and preventing the occurrence of water stress. They also play a role in the excretion of waste substances from the plant, such as excess salts or toxic compounds. Additionally, hydathodes aid in the elimination of gases from the plant, aiding in the process of gas exchange.
In conclusion, hydathodes are specialized structures in plants that enable the excretion of excess water, waste substances, and gases, thus helping to maintain water and metabolic balance within the plant.
