Hydathodes

Example:Morning dew-like droplets on leaf tips are a sign of guttation.

Definition:The process of exuding water droplets from the leaf tips or edges of plants, particularly overnight, due to the roots' ability to absorb more water than the plant can photosynthesize.

Example:Microscopic hydathodes on plant leaves facilitate the hydathode discharge under high humidity and light conditions.

Definition:The release of water vapor from specialized structures in plants, such as hydathodes, through the process of guttation.

Example:Phyllolem discharge can be observed on the underside of leaves, often mistaken for hydathode discharge.

Definition:A special type of discharge that occurs when water vapor is expelled from the phyllolem, the innermost layer of the epidermis of a leaf, similar to hydathode discharge.

Example:Hydathodes play a crucial role in exudation, managing water release from plants.

Definition:The process of secreting or emitting substances from plant cells or organs, including water vapor through specialized structures like hydathodes.

Example:In plant physiology, researchers might use specialized tools to study the activity of hydathodes in response to changing environmental conditions.

Definition:The study of the functioning of plants, including how they use water, manage nutrients, and respond to environmental stimuli, which often involves the study of structures like hydathodes.
