Bryophyte

 A bryophyte lacks vascular tissue, and is mainly only capable of growing/living in moist environments. The majority of bryophytes are mosses, which is why there is a photo of moss in the following picture. This moss was found at the bottom of a tree near a pond, which is why it can survive (because the evironment is usually moist).
