elater mechanism for seed dispersal is exhibited by
Elater An elater is a cell (or structure attached to a cell) that is hygroscopic, and therefore will change shape in response to changes in moisture in the environment. Elaters come in a variety of forms, but are always associated with plant spores. In many plants that do not have seeds, they function in dispersing the spores to a new location. Mosses do not have elaters, but peristome which also change shape with changes in humidity or moisture to allow for a gradual release of spores.
