abscisic acid
This term refers to a specific biochemical compound used in plant physiology. It is characterized by its role as a growth inhibitor, often acting as a chemical signal that tells the plant to conserve water or enter a dormant state to survive environmental stress.
As a chemical compound name, it is treated as an uncountable noun. It does not have a plural form in standard scientific usage, as it refers to the substance itself rather than individual units of the acid.
