Plants are considered rootless, with leaves that can be photosynthetic and in whorls along the stem, finely dissected, and/or linear. Much like roots, bladders (traps or utricles) may exude carbon and absorb other nutrients. These bladders may be culturing a mutualistic community and/or carnivorous. The bladders trap and contain much from the environment, such as algae, microinverterbrates, protists, bacteria, fungi, and detritus (Adamec 2006; Gordon & Pacheco 2007; Meis Chormanski 2007; Peroutka et al. 2008; Richards 2001; Sirová et al. 2010). Terrestrial species might rely more heavily on protists for nutrients instead of photosynthesis (Porembski et al. 2006).
