Hornwort sporocytes. Fluorescence light micrograph of a longitudinal section through a sporangium of a Phaeoceros carolinianus hornwort. The rounded trifold structures are sporocytes,part of the reproductive cycle of this plant. The sporocytes divide into spores (seen here as tetrads and elaters) that are dispersed on the wind to form new hornwort plants. Hornworts,liverworts and mosses are non-vascular plants collectively known as bryophytes. This sample has been stained with berberine,which fluoresces under ultraviolet (UV) light.
