Liverwort. Coloured scanning electron micrograph (SEM) of the stem of the a liverwort plant Frullania tamarisci. This species of liverwort has several small scale-like overlapping leaves (green). The white bottle-like structures are for water storage. F. tamarisci is an epiphytic species as it grows on other plants without harming them. It obtains its water from the air and rain. Liverworts are related to mosses. They grow in damp habitats and have no true vascular tissue, but are attached to the ground by means of root-like rhizoids which are also responsible for some absorption of water and nutrients.
