* Trees require vascular tissue: Trees, by definition, are tall, woody plants with a single, dominant stem. This structure relies on vascular tissue (xylem and phloem) to transport water and nutrients throughout the plant.
* What we call "non-vascular trees" are actually:
* Mosses: These are non-vascular plants that can grow in clumps and resemble a "tree" shape. However, they lack the internal plumbing system (xylem and phloem) that defines vascular plants.
* Liverworts and Hornworts: Similar to mosses, these are also non-vascular plants that can have a more intricate structure than mosses but still lack the defining features of trees.
In essence, there are no true "non-vascular trees." Any plant that exhibits the characteristics of a tree (tall, woody, single stem) will necessarily have vascular tissue.
