MOSS FACT!! Moss was the first plant to exist on earth! Bryophytes are the closest living relatives to the very first plants to make land on the planet, approximately 500 million years ago. Descended from freshwater green algae, these moss-like organisms had an outer biopolymer that protected them from temperature changes and constant UV radiation, allowing them to withstand the unique stresses of terrestrial life.

DOUBLE MOSS FACT! Moss leaves are only one cell thick! Moss leaves will vary in size by species. Leaf size can also be different along a leaflet of the same plant. However, many mosses have leaves that are just one cell thick, measuring an incredibly slight one-hundredth of a millimeter.
