What is elaters

Open in App
Solution

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 plantspores. 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.

"Elaters" is also used as a common name for the Elateridae (click beetles). For the click beetle genus, see Elater (beetle).

Hope this helps :)
