[1]These plants are small and thalloid, i.e. not differentiated into root, stem and leaf.Depending on species, the thallus may be strap-shaped and about 0.5 to 4 mm wide with dichotomous branches or may form rosettes or hemirosettes up to 3 cm in diameter, that may be gregarious and form intricate mats.
Non-vascular plant. Appearance. Mosses are examples of non-vascular plants. Non-vascular plants are plants without a vascular system consisting of xylem and phloem. Instead, they may possess simpler tissues that have specialized functions for the internal transport of water. [citation needed] Non-vascular plants include two distantly related ...
