Elaters are specialized, elongated cells found in the sporangia of certain groups of bryophytes, particularly liverworts and some hornworts. These structures play a crucial role in the dispersal of spores by aiding in their release when environmental conditions are favorable. Elaters respond to humidity changes, coiling and uncoiling to help propel the spores into the air, which is vital for the reproductive success of these non-vascular plants.
